Look no further, GEMMA is a tiny wearable platform board with a lot of might in a 1\" diameter package. Powered by a Attiny85 and programmable with an Arduino IDE over USB, you'll be able to realize any wearable project.\u003c\/p\u003e\n\u003cp\u003eWe wanted to design a microcontroller board that was small enough to fit into any project, and low cost enough to use without hesitation. Perfect for when you don't want to give up your Flora and you aren't willing to take apart the project you worked so hard to design. It's our lowest-cost sewable controller.\u003c\/p\u003e\n\u003cp\u003eNEW In version 2. On March 4, 2015 we released Version 2, which is physically and code-wise identical but has changed the Mini-B connection for a Micro-B USB connector and adds a much-requested On-Off switch.\u003c\/p\u003e\n\u003cp\u003eThe Attiny85 is a fun processor because despite being so small, it has 8K of flash, and 5 I\/O pins, including analog inputs and PWM 'analog' outputs. We designed a USB bootloader so you can plug it into any computer and reprogram it over a USB port just like an Arduino (it uses 2 of the 5 I\/O pins, leaving you with 3). In fact we even made some simple modifications to the Arduino IDE so that it works like a mini-Flora. Perfect for small \u0026amp; simple projects the GEMMA will be your go-to wearable electronics platform.\u003c\/p\u003e\n\u003cp\u003eEven though you can program GEMMA using the Arduino IDE, it's not a fully 100% Arduino-compatible. There are some things you trade off for such a small and low cost microcontroller.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cdiv\u003e\n\u003cp\u003eGEMMA does not have a Serial port connection for debugging so the serial port monitor will not be able to send\/receive data Some computers' USB v3 ports don't recognize the GEMMAs bootloader.
