Adafruit Metro M4 Express

Here comes the fastest, most powerful Metro ever. The Adafruit Metro M4 featuring the Microchip ATSAMD51. This Metro is like a bullet train, with it's 120MHz Cortex M4 with floating point support. METRO has 25 GPIO pins, 8 of which are analog in, and two of which is a true analog out. There's a hardware SPI port, hardware I2C port and hardware UART. Logic level is 3.3V.

This Metro is the same size as the others, and is compatible with all Adafruit shields. It's got analog pins where you expect, and SPI/UART/I2C hardware support in the same spot as the Metro 328 and M0. But! It's powered with an ATSAMD51J19:
- Cortex M4 core running at 120 MHz
- Hardware DSP and floating point support
- 512 KB flash, 192 KB RAM
- 32-bit, 3.3V logic and power
- Dual 1 MSPS DAC (A0 and A1)
- Dual 1 MSPS ADC (8 analog pins)
- 6 x hardware SERCOM (I2C, SPI or UART)
- 16 x PWM outputs
- Stereo I2S input/output with MCK pin
- 10-bit Parallel capture controller (for camera/video in)
- Built in crypto engines with AES (256 bit), true RNG, Pubkey controller

There's a working Arduino board support package, with lots of stuff working, but the primary target for this board is CircuitPython - with 120 MHz, and 192KB of RAM CircuitPython runs really well on this chip! 2 MB QSPI Flash storage chip is included on board. You can use the SPI Flash storage like a very tiny hard drive. When used in Circuit Python, the 2 MB flash acts as storage for all your scripts, libraries and files. When used in Arduino, you can read/write files to it, like a little datalogger or SD card, and then with our helper program, access the files over USB.
