A-Star Programmer Controllers 비교표 보러가기
he 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 16 MHz resonator and a 5 V regulator that can be powered from 5.5 V to 15 V supplies.
Description :
The Pololu A-Star 328PB Micro is a general-purpose programmable module based on the ATmega328PB AVR microcontroller, which has 32 KB of flash program memory and 2 KB of RAM. The ATmega328PB is a backward-compatible, improved replacement for the popular ATmega328P found on other programmable modules like our Baby Orangutan B-328 and the Arduino Uno and Pro Mini, so programs written for those other boards will generally work on the A-Star 328PB Micro with appropriate adjustments for any differences in clock speed. On-board features of the A-Star (abbreviated A*) include a resonator, user and power LEDs, and a reset button. The board includes a low-dropout linear voltage regulator that allows it to be powered from external supplies up to 15 V, and reverse voltage protection on this main power input helps safeguard against accidental damage. The board can also be powered through its TTL serial header by a USB-to-serial adapter, and an integrated power switching circuit makes it safe to have both supplies connected at the same time.
The A-Star 328PB Micro breaks out 19 general-purpose I/O lines along two rows of pins, including seven usable as PWM outputs and eight usable as analog inputs; another five GPIO pins (including two usable as PWM outputs) can be accessed along the bottom edge of the board. It provides both an in-system programming (ISP) header and a connector for TTL serial programming along the top edge. The board fits all this into a 1.3″ × 0.7″ area (the same size as the Arduino Pro Mini), and its 0.1″ pin spacing makes the A* easy to use with solderless breadboards, perfboards, and 0.1″-pitch connectors.
The A-Star 328PB Micro is available in four logic voltage and resonator frequency combinations:
Each of the four versions uses a different power LED color as a way to differentiate them.
Our comprehensive user’s guide provides the basics you need to get started with the A-Star 328PB Micro as well as detailed technical information for advanced users.
Either a USB-to-serial adapter or an AVR in-system programmer (ISP) is required to program the A-Star 328PB Micro from a computer. We recommend our USB AVR Programmer v2, which can be used as both.
Features :
This version has a 5 V regulator that can be powered from 5.5 V to 15 V, and it features a 16 MHz resonator, which matches the voltage and clock speed of the Arduino Uno. It can be distinguished from other versions by its blue power LED:

A-Star 328PB Micro – 5V, 16MHz.
The A-Star 328PB ships with a preloaded Arduino-compatible TTL serial bootloader (which uses 0.5 KB of flash memory, leaving 31.5 KB available for the user program). We provide a software add-on that enables the board to be easily programmed from the Arduino environment.
Since the A-Star’s ATmega328PB microcontroller is backward-compatible with the ATmega328P commonly used on Arduino boards (like the Arduino Uno and Pro Mini), existing programs and libraries written for a standard Arduino can be used on the A-Star 328PB without any changes (except to account for clock speed differences when necessary). However, our add-on includes support for the new features on the ATmega328PB, making them easier to use from the Arduino environment and allowing the A-Star 328PB to be an upgrade from ATmega328P-based boards.
The A-Star 328PB is the same size as the Arduino Pro Mini. It can similarly be used as a compact, minimal alternative to a standard full-size Arduino, but since its pinout differs, this board is not a drop-in replacement for the Pro Mini.
Compared to the ATmega328P (and ATmega328), the ATmega328PB microcontroller offers a number of improvements, including:
The ATmega328PB is code-compatible with the ATmega328P, meaning code compiled for an ATmega328P will run as intended on an ATmega328PB. This application note (283k pdf) by Atmel (now part of Microchip) comprehensively describes the differences between the ATmega328PB and its predecessors.
Our Arduino software add-on makes it easy to use the additional GPIO functionality, PWM outputs, and TTL serial port. The other new features of the ATmega328PB can still be used from the Arduino environment through direct register access or custom libraries.
This diagram identifies the I/O and power pins on the A-Star 328PB Micro; it is also available as a printable PDF (579k pdf). For more information about the ATmega328PB microcontroller on this board, see Microchip’s ATmega328PB documentation.
Printed on the A* circuit board are indicators that you can use to quickly identify each pin’s capabilities: pins labeled with A0 through A7 can be used as an analog input, and a square wave symbol under the pin number means it can be used as a PWM output. All of the pins are labeled on the bottom silkscreen, and some of the pins are also labeled on the top silkscreen (as space allows).
The board can be powered either through a USB-to-serial adapter connected to its serial header or from a source up to 15 V on the BAT+ pin, which is reverse-voltage protected and reduced to 3.3 V or 5 V by a 100 mA low-dropout (LDO) regulator. The A-Star 328PB Micro includes a switching circuit that makes it safe to have both VCCIN and BAT+ power supplies connected at the same time. Reverse-protected power can be supplied to other devices by using the VIN pin as an output, and the logic voltage supply is available on the VCC output. Alternatively, the external supply can be connected directly between VIN and GND, bypassing the reverse-voltage protection.
