A-Star 328PB Micro 3.3V 8MHZ - Compatible with Arduino®
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 pre-loaded 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 an 8 MHz resonator and a 3.3 V regulator that can be powered from 3.8 V to 15 V supplies.
Quick Spec
- Processor: ATmega328PB @ 8MHz
- RAM size: 2048 bytes
- Program memory size: 32 Kbytes (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.)
- Motor channels: 0
- User I/O lines: 24 (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.)
- Minimum operating voltage: 3.8 V
- Maximum operating voltage: 15 V
- Logic voltage: 3.3 V
- Reverse voltage protection?: Yes, On BAT+
- External programmer required?: No
- Version: 3.3 V logic, 8 MHz resonator
