Adafruit Gemma – Miniature Wearable Arduino-like Electronic Platform
Love the wearable electronic platform – FLORA but want a smaller version? Look no further, GEMMA is a tiny wearable platform board 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.
This microcontroller board is 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.
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
