A Star 328PB Micro

The 328PB microcontroller module offers a compact, programmable platform built around the ATmega328PB AVR core. It retains full compatibility with the widely used ATmega328P while adding extra general‑purpose I/O pins and a richer set of peripheral interfaces, such as additional timers, PWM channels and serial ports. Available in both 3.3 V and 5 V versions, the module can run at a range of clock speeds to match power or performance requirements. Its small footprint and straightforward pinout make it easy to integrate into breadboard prototypes, PCB designs or shielded systems, providing reliable operation for sensor acquisition, motor control and basic embedded logic.
