Adafruit Feather M0 Express - Designed for CircuitPython (ATSAMD21 Cortex M0) _ARD_SHIELD_LED Unlike other GSM/GPRS modules

Unlike other GSM/GPRS modules

2025 - We revised the backpack now to have Stemma QT connectors for easy plug-and-play of matrices once they are soldered together

These are the same integrated LEDs that are used in our new fancy DotStar strips just really small

It has a roomy 512KB of flash and 192KB of SRAM so it's great for CircuitPython

We suggest a TIP120 or N-Channel power FET with a 1N4001 kickback diode to drive this from a microcontroller pin

It's our first Feather that is specifically designed for use with CircuitPython! CircuitPython is our beginner oriented flavor of MicroPython and as the name hints at, its a small but full featured version of the popular Python programming language specifically for use with circuitry and electronics. Please note, CircuitPython does not come preloaded. See the full guide linked below
