The FPB-RA4E1 board is designed with an architecture similar to other boards in the FPB series. Alongside
the MCU there is an on-board programmer, pin headers for access to all the pins on the MCU, a power
supply regulator, some LEDs and switches, and several ecosystem I/O connectors (Pmod and Arduino).
