Adafruit GEMMA M0 - Miniature wearable electronic platform

Same size, form-factor, and pinout as classic Gemma. Three big-hole sew-pads can be used for conductive thread or alligator-clips for fast prototyping. Each I/O pad can be used for 12-bit analog input, or digital input/output with internally connected pullups or pulldowns 256KB Flash - 8x as much as 8 KB on ATtiny85, 32 KB RAM - 64x as much as 512 bytes on ATtiny85 48 MHz 32 bit processor - 6x as fast as ATtiny85 (not even taking into account 32-bit speedups) Native USB supported by every OS - can be used in Arduino or CircuitPython as USB serial console, Keyboard/Mouse HID, even a little disk drive for storing Python scripts. (ATtiny85 does not have native USB) Can be used with Arduino IDE or CircuitPython. Built in RGB DotStar LED, Manufacturer: Adafruit
