NEW GUIDE: Adafruit Feather M4 Express #Feather @MicrochipMakes #SAMD51
The newest member of the Adafruit Feather Microcontroller ecosystem is here!
It’s what you’ve been waiting for, the Feather M4 Express featuring the Microchip Technology ATSAMD51. This Feather is fast like a swift, smart like an owl, strong like a ox-bird (it’s half ox, half bird, OK?) This feather is powered by our new favorite chip, the ATSAMD51J19 – with its 120MHz Cortex M4 with floating point support and 512KB Flash and 192KB RAM. Your code will zig and zag and zoom, and with a bunch of extra peripherals for support, this will for sure be your favorite new chipset.
Here are some of the updates you can find when using the Feather M4:
Measures 2.0″ x 0.9″ x 0.28″ (51mm x 23mm x 8mm) without headers soldered in
Light as a (large?) feather – 5 grams
ATSAMD51 32-bit Cortex M4 core running at 120 MHz, 32-bit, 3.3V logic and power
Hardware DSP and floating point support
512 KB flash, 192 KB RAM
2 MB SPI FLASH chip for storing files and CircuitPython code storage.
32.768 KHz crystal for clock generation & RTC
3.3V regulator with 500mA peak current output
USB native support, comes with USB bootloader and serial port debugging
Built in crypto engines with AES (256 bit), true RNG, Pubkey controller
Tons of GPIO! 21 x GPIO pins with following capabilities:
Dual 1 MSPS 12 bit true analog DAC (A0 and A1) – can be used to play 12-bit stereo audio clips
Dual 1 MSPS 12 bit ADC (6 analog pins some on ADC1 and some on ADC2)
6 x hardware SERCOM – Native hardware SPI, I2C and Serial all available

Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know – adafruit.com/vote
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
