Brain -- aka ATSAME54P20A_AU\n - 120Mhz Core Clock\n - 32khz External Clock (for startup)\n - 12(?)Mhz Alt Clock (probably unused, but adding it just in case)\n - 3 Sercoms\n    - 1 I2C\n    - 1 SPI\n    - 1 U(S)ART\n - Interfaces with IO Extender for parallel bus control without sacrificing pins\n - The E54 has a shitty pin set for parallel control (not bc of no. of pins, but \nbecause of positions and default pin functions)
