The development board is a microcontroller board based on ATmega32P-AU chip design, it has 23 input/output pins, a 16 MHz crystal oscillator, a Micro USB interface, and a reset button. The biggest feature of this board is the shared pins on the board. Upload different programs to it, and follow the pinout to switch between the Nano development board and the Raspberry Pi development board.
