Are you ready? Really ready? Cause here comes the Adafruit Grand Central featuring the Microchip ATSAMD51. This dev board is so big, it's not named after a Metro train, it's a whole freakin' station!
This board is like a freight train, with its 120MHz Cortex M4 with floating point support. 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.
The Grand Central is the first SAMD board that has enough pins to make it in the form of the Arduino Mega - with a massive number of pins, tons of analog inputs, dual DAC output, 8 MBytes of QSPI flash, SD card socket, and a NeoPixel.
This version is lower cost and lower profile, we didn't solder any of the through-hole components in. Perfect if you want to solder directly to the board, or jam it into a small spot in your build. We include only the assembled and tested board, a loose 2.1mm DC jack and bumpers. If you need a classic header-full Grand Central, visit this page.
To start off our ATSAMD51 journey we are going large with the Mega shape and pinout you know and love. The front half has the same shape and pinout as our Metro's, so it is compatible with all our 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 ATSAMD51P20:
Pretty good start right? So we put this chip on a PCB with all these nice extras:
We have a working Arduino board support package, with lots of stuff working, but our primary target for this board is CircuitPython - with 120 MHz, and 256KB of RAM CircuitPython runs really well on this chip!
