Adafruit’s Tiny GEMMA M0 for Wearables Projects Now Shipping from Mouser Electronics

Mouser Electronics, Inc., the New Product Introduction (NPI) leader that empowers innovation, is now stocking the Adafruit GEMMA M0 development board. The latest generation of Adafruit’s GEMMA series of development boards, GEMMA M0 is a tiny 28mm × 7mm microcontroller board with alligator-clip sew pads for solderless wearable applications.

The Adafruit GEMMA M0, available from Mouser Electronics, 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. Additionally the board supports the Arduino integrated development environment (IDE). The board features an on/off switch, reset switch, JST battery connector, and a built-in Adafruit DotStar RGB LED.

GEMMA M0 boasts three general-purpose input/output (GPIO) pads, each offering 12-bit analog input or digital input/output and supporting capacitive touch. These GPIO pads use the exact same names as the original GEMMA development board, meaning that any existing Arduino code will continue to work without changes with the GEMMA M0. All three pads can be used as hardware capacitive touch sensors, and they can drive NeoPixels or DotStars on any pins.
