[3DMakerWorld] Adafruit Grand Central M4 Express feat. SAMD51 without Headers

Description

Key Features:
Same shape and pinout as our Metro's, so it is compatible with all Adafruit's shields
2.1mm DC jack has an on/off switch next to it so you can turn off your setup easily
No need for a hardware USB to Serial converter as the Metro M4 has built in USB support
Pre-loaded with the UF2 bootloader, which looks like a USB storage key
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.
