ATmega328PB is a low-power CMOS 8-bit microcontroller based on AVR@ enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATmega328PB achieves throughput of nearly 1MIPS per MHz. This enables system designers to optimize the device's power consumption and processing speed. In this solution, USB is used to take power and convert it to 3.3V to supply power to the microcontroller, and all IO ports are drawn out to facilitate testing.
