Description
A-star 328PB Micro is based on AVR ATmega 328PB microcontroller which, due to backward compatibility, can be a substitute for such modules as the Arduino Uno or Pro Mini equipped with old versions of this microcontroller so the programs written for these boards needs to work on it. It is equipped with 24 digital pins of input / output, 9 of which can be used as PWM outputs and 8 as analog inputs. The system works with voltages of 5 V, works with a clock signal with a frequency of 20 MHz.

The module has no soldered goldpin connectors (included) so the user decides which leads will be needed so the board can maintain its small size.
Insights
Power
The module can be powered with the voltage from 5.5 V to 15 V by connecting it to the VIN lead which is connected with stabilizer.
In our offer, you will find compatible power supplies.
Inputs / Outputs
A-Star has 24 digital outputs input/output (I/O). In addition to standard I/O, some of the leads also have special functions. It may be supported by using interfaces: IPS, USART, TWI
Programming
Creating and downloading software, is allowed by the free environment of the Arduino IDE. Implemented bootloader allows you to send the program through the USB-UART converter, via the ISP pins using the AVR programmer.
