FLORA by Adafruit industries

Posted by on Jan 20, 2012 in Open design | No Comments

Adafruit industries is adding some competition in the field of wearable technologies hardware. For a while now, e-textiles experimentation has become synonymous with Leah Buechley’s LilyPad Arduino, which came out in 2007, but FLORA is soon to add some much-needed diversity. Personally, I can’t wait to get my hands on FLORA! More options can only result in more creativity!

Like LilyPad, FLORA is designed for e-textile uses and is an open-source wearable electronics platform, which comes with a series of accessories, projects and tutorials. Adafruit has for some time now been leading the pack in online electronics community building – so I can only imagine some pretty positive knowledge being shared in the coming months.  Although not yet officially launched, you can put yourself on a list to be notified when they do ship! Here is a promo video, and the facts about FLORA:

- The FLORA is small (1.75″ diameter).
- The FLORA has built-in USB support. Built in USB means you plug it in to program it, it just shows up. 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. Either will work great.
- The FLORA has USB HID support, so it can act like a mouse, keyboard, MIDI, etc. to attach directly to cellphones. Our iPhone/iPad/Android app coming soon.
- The FLORA’s modules include: Bluetooth, GPS, 3-axis accelerometer, compass module, flex sensor, piezo, IR LED, push button, embroidered + capacitive keypad, OLED and more.
- The FLORA has a small but easy to use onboard reset button to reboot the system.
- 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 has an onboard 3.3v 100mA regulator with protection schottky diode and USB fuse so that power is consistent and can power common 3.3v modules and sensors.
- The FLORA has 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.
- 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 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 extremely beginner-friendly – it is difficult to destroy the FLORA by connecting a battery backwards due to polarized connector and protection diodes. The onboard 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.
- The FLORA has an ICSP connector for easy reprograming for advanced users.
- The FLORA has 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 bootloader (not released) and will work with any future released Leonardo-compatible bootloader. FLORA is currently using our Adafruit 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 2012 and has staff 100% dedicated to creating tutorials and projects for use with the FLORA.

- 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.
