When I first mentioned Snek a few months ago, Phillip Torrone from Adafruit pointed me at their Metro M0 board, which uses an Arduino-compatible layout but replaces the ATMega 328P with a SAMD21G18A. This chip is an ARM Cortex M0 part with 256kB of flash and 32kB of RAM. Such space!
Even though there is already a usable MicroPython port for this board, called CircuitPython, I figured it would be fun to get Snek running as well. The CircuitPython build nearly fills the chip, so the Circuit Python boards all include an off-chip flash part for storing applications. With Snek, there will be plenty of space inside the chip itself for source code, so one could build a cheaper/smaller version without the extra part.
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.
