Product description

Description Product Description 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! The 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 & simple projects the GEMMA will be your go-to wearable electronics platform. Even 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! GEMMA 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. Simply use a USB v2 port or a USB hub in between We do not have full Windows 8 driver compatibility tested. At this time we only have it working with Mac, Linux or Windows 7/XP Box Contains 1 x Adafruit Gemma V2 microcontroller

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days โ€” so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
