ADAFRUIT GEMMA M0 development board is a tiny 28mm × 7mm microcontroller board with alligator-clip sew pads for solderless wearable applications. Product adds power on top of the original Gemma board’s ease of use, replacing the ATtiny85 microcontroller with a more powerful Microchip ATSAMD21E18 Arm Cortex-M0+ microcontroller, 32 kBytes of RAM, and 256 kBytes of flash. The microcontroller features native USB supported by every operating system, which removes the need to download additional software for use. The board ships with Adafruit’s CircuitPython programming language, so makers and engineers of all skill levels can use the GEMMA M0 out of the box without downloading software. Product supports the Arduino integrated development environment (IDE) and features an on/off switch, reset switch, JST battery connector, plus a built-in Adafruit DotStar RGB LED.
