New! Version 3 comes with the latest module which has external antenna support and Pulse-Per-Second output We carry a few different GPS modules here in the Adafruit shop, but none that satisfied our every desire - that's why we designed this little GPS breakout board. We believe this is the Ultimate GPS module, so we named it that. It's got everything you want and more -165 dBm sensitivity, 10 Hz updates, 66 channels 5V friendly design and only 20mA current draw Breadboard friendly + two mounting holes RTC battery-compatible Built-in datalogging PPS output on fix 25Km altitude Internal patch antenna + u.FL connector for external active antenna Fix status LED ...all for under 40! The breakout is built around the MTK3339 chipset, a no-nonsense, high-quality GPS module that can track up to 22 satellites on 66 channels, has an excellent high-sensitivity receiver (-165 dB tracking!), and a built in antenna. It can do up to 10 location updates a second for high speed, high sensitivity logging or tracking. Power usage is incredibly low, only 20 mA during navigation. Best of all, we added all the extra goodies you could ever want a ultra-low dropout 3.3V regulator so you can power it with 3.3-5VDC in, 5V level safe inputs, ENABLE pin so you can turn off the module using any microcontroller pin or switch, a footprint for optional CR1220 coin cell to keep the RTC running and allow warm starts and a tiny bright red LED. The LED blinks at about 1Hz while it's searching for satellites and blinks once every 15 seconds when a fix is found to conserve power. If you want to have an LED on all the time, we also provide the FIX signal out on a pin so you can put an external LED on. Two features that really stand out about version 3 MTK3339-based module is the external antenna functionality and the the built in data-logging capability. The module has a standard ceramic patch antenna that gives it -165 dB sensitivity, but when you want to have a bigger antenna, you can snap on any 3V active GPS antenna via the uFL connector. The module will automatically detect the active antenna and switch over! Most GPS antennas use SMA connectors so you may want to pick up one of our uFL to SMA adapters. The other cool feature of the new MTK3339-based module (which we have tested with great success) is the built in datalogging ability. Since there is a microcontroller inside the module, with some empty FLASH memory, the newest firmware now allows sending commands to do internal logging to that FLASH. The only thing is that you do need to have a microcontroller send the Start Logging command. However, after that message is sent, the microcontroller can go to sleep and does not need to wake up to talk to the GPS anymore to reduce power consumption. The time, date, longitude, latitude, and height is logged every 15 seconds and only when there is a fix. The internal FLASH can store about 16 hours of data, it will automatically append data so you don't have to worry about accidentally losing data if power is lost. It is not possible to change what is logged and how often, as its hardcoded into the module but we found that this arrangement covers many of the most common GPS datalogging requirements. We've tested this version of the Ultimate GPS in a high-altitude balloon, and it kept fix up to 27km! Comes with one fully assembled and tested module, a piece of header you can solder to it for breadboarding, and a CR1220 coin cell holder. A CR1220 coin cell is not included, but we have them in the shop if you'd like to use the GPS's RTC We have a nice fancy library for GPS usage, with background parsing and can set and query the built in GPS logging capability (called LOCUS). A full tutorial is also available, which has tons of information about the module, how to use the data logger and more

FLORA - Wearable electronic platform Arduino-compatible - For the last few years Ladyada has been thinking about everything she wanted in a wearable electronics platform for Adafruit's community of makers, hackers, crafters, artists, designers and engineers. After months of planning, designing and working with partners around the world for the best materials and accessories, we can share what we're up to. The hardware is now shipping! We call it the FLORA. Adafruit created the FLORA from scratch after many months of research and we really think we came up with something that will empower some amazing wearable projects. The FLORA is small (1.75 diameter, weighing 4.4 grams). We wanted the smallest possible board for our wearable platform. In the FLORA family we also have the best stainless steel threads, sensors, GPS modules and chainable LED pixels, perfect accessories for the FLORA mainboard The FLORA has built-in USB support. Built in USB means you plug it in to program it, it just shows up - all you need is a USB cable, no additional purchases are needed! Works with Mac, Windows, Linux, any USB cable works great. Currently the PCB comes with a mini B connector but future versions may change to microUSB. The FLORA has USB HID support, so it can act like a mouse, keyboard, MIDI, etc. to attach directly to cellphones. The FLORA has a small but easy to use onboard reset button to reboot the system. The power supply is deigned to be flexible and easy to use. There is an onboard polarized 2 JST battery connector with protection schottky diode for use with external battery packs from 3.5v to 16v DC in. Can be used with LiIon/LiPoly, LiFe, alkaline or rechargeable NiMh/NiCad batteries of any size. The FLORA does not have a LiPo charger included by design, this allows safe use with multiple battery types and reduces risk of fire as it is not recommended to charge these batteries on fabric. We suggest a micro LiPo charger if you want to use LiPo batteries with FLORA The FLORA has onboard power switch connected to 2A power FET for safe and efficient battery on/off control. Often FETs are not included in other designs that leads to switch failure as small SMT switches are rated for only 20mA current use. The FLORA has an onboard 3.3v 100mA regulator with protection diode and USB fuse so that power is consistent and can power common 3.3v modules and sensors. We spent a lot of time on the power supply because the FLORA power system is specifically designed to allow easy control and power of a large quantity of digital RGB LED pixels such as the FLORA pixel series of accessories. The FLORA is fabric friendly. The FLORA does not use FTDI headers (built in USB support) headers of any kind sticking out can grab and tear fabric. The FLORA is extremely beginner-friendly - it is difficult to destroy the FLORA by connecting a battery backwards due to polarized connector and protection diodes. The on-board regulator means that even connecting a 9V battery will not result in damage or tears. The FLORA has 4 indicator LEDs power good, digital signal LED for bootloader feedback, data rx/tx. Also onboard is an ICSP connector for easy reprograming for advanced users. There are 14 sewing tap pads for attachment and electrical connections. Data buses are interleaved with power and ground pads for easy module and sensor attachments without worrying about overlapping traces which are not possible with conductive thread. The FLORA works with the Adafruit-fixed Leonardo-like bootloader and will work with any future released Leonardo-compatible bootloader. FLORA is currently using our bootloader and Adafruit USB vendor ID. The FLORA comes with Adafruit's support, tutorials and projects. Adafruit has dozens of projects that will be released with the FLORA in 2013 and has staff 100 dedicated to creating tutorials and projects for use with the FLORA. The FLORA is not the first wearable Arduino / Arduino-compatible. Leah Buechleys Lilypad was developed in 2007 we wanted to also make something thats wearable, but it needed to be a completely new platform for our accessories/modules and goals for the project. The FLORA is made in NYC at Adafruit, it was designed by Limor Fried (Ladyada) she is an Electrical Engineer with a proven track record of providing over 26 high-quality libraries for Arduino/Arduino IDE, over 100 tutorials, open-source code and contributions to the Arduino project. She was a member of the MIT wearables group and likes to sew.

We've taken our popular Adafruit PN532 breakout board and turned it into a shield - the perfect tool for any 13.56MHz RFID or NFC application. The Adafruit NFC shield uses the PN532 chip-set (the most popular NFC chip on the market) and is what is embedded in pretty much every phone or device that does NFC. This chipset is very powerful, and can pretty much do it all, such as read and write to tags and cards, communicate with phones (say for payment processing), and 'act' like a NFC tag. While the controller has many capabilities, our Arduino library currently only supports reading/writing tags, and does not support phone-to-shield communication, tag emulation (which requires an external 'secure element' only available from NXP) or other more advanced features at this time. NFC (Near Field Communications) is a way for two devices very close to each other to communicate. Sort of like a very short range bluetooth that doesn't require authentication. It is an extension of RFID, so anything you can do with RFID you can do with NFC. Because it can read and write tags, you can always just use this for RFID-tag projects. We carry a few different tags that work great with this chip. It can also work with any other NFC/RFID Type 1 thru 4 tag (and of course all the other NXP MiFare type tags) The Adafruit shield was designed by RF engineers using the best test equipment to create a layout and antenna with 10cm (4 inch) range, the maximum range possible using the 13.56MHz technology. You can easily attach the shield behind a plastic plate with standoffs and still read cards through a (non-metal) barrier. This shield is designed to use I2C or SPI communication protocols. I2C is the default, as it uses fewer pins analog 4 and 5 are used for I2C (of course you can still connect other I2C devices to the bus). Digital 2 is used for interrupt notification. This means you don't have to sit there and 'poll' the chip to ask if a target tag has been found, the pin will pull low when a card, phone, etc is within range. You can adjust which pin is used if you need to keep digital 2 for something else. It is also easy to change the shield over to SPI where you can use any 4 digital pins by shorting two solder jumpers on the top of the PCB. Compatible with any classic Arduino - NG, Diecimilla, Duemilanove, UNO - as well as Mega R3 or later. For using the I2C interface with Mega R2 or earlier, two wires must be soldered as the I2C pins are in a different location on earlier Megas. Comes with the Adafruit NFC/RFID PN532 shield including a tuned 13.56MHz stripline antenna, 36-pin 0.1 header for attaching the shield to an Arduino. If you want to stack another shield on top or below, check out our stacking headers that allow pass-through stacking. We also toss in a Mifare Classic 1K card! (You can get more tags from us here) Check out our RFID/NFC project page for documentation, libraries, and other support Please note that there is a minor issue with the current version of the boards (v1.0). SEL0 and SEL1 are reversed on the silkscreen, so SEL0 is actually SEL1 and vice versa. This only affects users who wish to use UART or SPI to communicate with the PN532 instead of the default I2C, which is the communication bus supported by Adafruit's PN532/NFC library for Arduino. This will be update on the next version of the boards.

Because the Arduino (and Basic Stamp) are 5V devices, and most modern sensors, displays, flash cards and modes are 3.3V-only, many makers find that they need to perform level shifting/conversion to protect the 3.3V device from 5V. We do have some other handy level shifters in the shop, from the DIP 74LVC245 to the fancy bi-directional TXB0108. However, neither of these are happy to work with I2C, which uses a funky pull-up system to transfer data back and forth. This level shifter board combines the ease-of-use of the bi-directional TXB0108 with an I2C-compatible FET design following NXP's app note. This breakout has 4 BSS138 FETs with 10K pullups. It works down to 1.8V on the low side, and up to 10V on the high side. The 10K's do make the interface a little more sluggish than using a TXB0108 or 74LVC245 so we suggest checking those out if you need high-speed transfer. While we designed it for use with I2C, this works great for SPI, TTL Serial, and any other digital interface both uni-directional and bidirectional. Comes with a fully assembled, and tested PCB with 4 full bidirectional converter lines as well as 2 pieces of 6-pin header you can solder on to plug into a breadboard or perfboard.
