Adafruit Feather M0 Express - CircuitPython & Arduino IDE Compatible
The Adafruit Feather M0, also known as the Adafruit Biblo M0, may be small in size, but don't let that deceive you! It's a microcontroller board built around the Atmel ATSAMD21 chip, packing a lot of power into a tiny package. We designed it to be small enough to fit into any project and cost-effective enough for you to use without hesitation. It's perfect for those times when you don't want to part with your expensive development board or break apart a project you've worked hard on. This is our most budget-friendly CircuitPython programmable board!
The Trinket M0 has replaced the lightweight ATtiny85 with an ATSAMD21E18 powerhouse. It's just as small but easier to use, allowing you to do more.
One of the most exciting features of the Trinket M0 is that while you can use it with the Arduino IDE, we ship it with CircuitPython on board. When you plug it in, it will appear as a very small disk drive with main.py on it. Use your favorite text editor to modify main.py and build your project using the most popular programming language, Python. No setup, IDE, or compiler needed, so you can use it on any computer, even Chromebooks or computers where you can't install software. When you're done, unplug the Biblo M0, and your code goes with you. Check out the Trinket M0 CircuitPython guide for a list of capabilities and quick-start code examples. - CircuitPython is easier to code but not as low-level or complete as Arduino.
Features
- Same size, form factor, and pinout as the classic Biblo
- Upgraded from the ATtiny85 8-bit AVR to the ATSAMD21E18 32-bit Cortex M0+
- 256 KB Flash, compared to 32x 8 KB on the ATtiny85
- 32 KB RAM, compared to 64x 512 bytes on the ATtiny85
- A 48 MHz 32-bit processor, six times faster than the ATtiny85 even without accounting for 32-bit speedups
- Native USB support compatible with all operating systems - can be used as a USB serial console, Keyboard/Mouse HID, or even a tiny USB drive for storing Python scripts (the ATtiny85 has no native USB)
- Usable with Arduino IDE or CircuitPython
- Built-in green ON LED
- Built-in red pin #13 LED
- Built-in RGB DotStar LED
- All 5 GPIO pins are available, not shared with USB so you can use them for what you like!
- Five GPIO pins with digital input/output with internal pull-up or pull-down available.
- All 5 GPIO pins support 12-bit analog input.
- One GPIO pin has true analog output for smooth audio playback with 10-bit quality (CircuitPython does not have audio playback support).
- We kept the M0 pads the same names as the original Trinket so all existing Arduino code will work exactly the same way as it did.
- Two high speed PWM outputs - for servos, LEDs, etc.
- Three pins can be used as hardware capacitive touch sensors with no additional components required
- Enough memory for 8000+ pixels with NeoPixels or DotStars on any pin, DMA-NeoPixel support on a pin so you can send pixel data without having to spend any processor time on it.
- Native hardware SPI, I2C and Serial available so you can use real hardware support and not bit-bang
- A single reset button for starting your project code over
- Can be powered via USB or external output (like a battery) - it'll automatically switch over
- Mounting holes! Yes!
- Really really small
Each order comes with one CircuitPython programmed and tested Trinket M0, with the full text editor Arduino IDE you can run most Arduino projects you already have.
