## Description

The Adafruit GEMMA M0 is a tiny, coin-sized microcontroller board designed for wearable electronics and small projects. Despite its quarter-sized footprint, it packs serious power with an ATSAMD21E18 32-bit Cortex M0+ processor, 256 KB of Flash, and 32 KB of RAM — a massive upgrade over the original ATtiny85-based Gemma. The GEMMA M0 ships with CircuitPython pre-loaded. Plug it in, edit the main.py file with any text editor, and your project is ready — no IDE or compiler installation required. It also works with the Arduino IDE for those who prefer C/C++. Key Features ATSAMD21E18 32-bit Cortex M0+ – 48 MHz processor with 256 KB Flash and 32 KB RAM Native USB – Works as a serial console, keyboard/mouse HID, or small disk drive on every OS CircuitPython and Arduino Support – Program with Python or C/C++, no special software installation needed Three Sew-Pads with Alligator-Clip Holes – Easy connections with conductive thread or clips for fast prototyping 12-bit Analog Input – On each I/O pad, with internal pullups/pulldowns True Analog Output – One pad supports 10-bit audio playback Two High-Speed PWM Outputs – Drive servos, LEDs, and more Hardware Capacitive Touch – All three pads work as touch sensors with no extra components NeoPixel and DotStar Support – Drive 8,000+ pixels on any pin, with DMA-NeoPixel support on one pin for zero processor overhead Hardware I²C and Serial – True hardware support on two pads (no bit-banging) Built-in RGB DotStar LED – For status indication or visual feedback On/Off Switch and Reset Button – Convenient power and restart controls JST Battery Connector – For AAA or LiPo batteries (no built-in LiPo charging, safe for NiMH/alkalines) Ideal For Wearable electronics and e-textile projects Small interactive LED installations Beginner-friendly CircuitPython learning Rapid prototyping with alligator clips Portable, battery-powered projects Package Contents 1× Adafruit GEMMA M0 – Fully assembled and tested, with CircuitPython and example code pre-loaded Note: The GEMMA M0 has the same pinout as the original Gemma, so existing Arduino code works without changes. USB cable not included. Resources Adafruit GEMMA M0 Learn Guide CircuitPython DMA-Driven NeoPixels Guide
