A-Star 328PB Micro - 3.3V, 12MHz
The A-Star 328PB Micro is a tiny programmable module featuring the ATmega328PB AVR microcontroller, a backward-compatible replacement for the popular ATmega328P that features more general-purpose I/O and many additional peripherals. This module provides access to all 24 digital input/output pins (of which 9 can be used as PWM outputs and 8 as analog inputs), all on a board measuring only 1.3″ × 0.7″. It ships preloaded with an Arduino-compatible serial bootloader that enables programming through the Arduino IDE via a USB-to-serial adapter, and the ISP pins are accessible for programming with an AVR programmer. This version features a 12 MHz resonator and a 3.3 V regulator that can be powered from 3.8 V to 15 V supplies.

- Without included optional headers.
- Note that 512 bytes of the MCU's 32 KB of flash memory is used by the pre-installed serial bootloader. All 32 KB is available when programming via the ISP header rather than the bootloader.
- All 24 can be used as digital I/O and 8 can be used as analog inputs. 19 of the 24 are available along the sides for use in a breadboard; the remaining five are accessible along the bottom edge.
- On BAT+.
