Electronic supplier, developer and manufacturer Adafruit has announced the arrival of the new addition to their range of hardware in the form of the Adafruit METRO M0 Express which has been specifically designed for CircuitPython ATSAMD21G18.
To recap the Metro hardware is Adafruit’s series of microcontroller boards for use with the Arduino IDE and although the new Metro M0 Express board looks very much like the original Metro 328 the new board offers a huge upgrade in comparison.
Adafruit explains more:
Instead of the ATmega328, this Metro features a ATSAMD21G18 chip, an ARM Cortex M0+. It’s our first Metro that is 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. Not only can you use CircuitPython, but the Metro M0 is also usable in the Arduino IDE.
At the Metro M0’s heart is an ATSAMD21G18 ARM Cortex M0 processor, clocked at 48 MHz and at 3.3V logic, the same one used in the new Arduino Zero. This chip has a whopping 256K of FLASH (8x more than the Atmega328) and 32K of RAM (16x as much)! This chip comes with built in USB so it has USB-to-Serial program & debug capability built in with no need for an FTDI-like chip.
