Pro Mini ATmega328P 3.3V/8MHz Development Board – Compatible with Arduino Pro Mini
The Pro Mini ATmega328P 3.3V/8MHz Board is a compact, low-power development board designed for space-constrained projects. It uses the ATmega328 microcontroller and runs at 8MHz, making it ideal for battery-powered applications and projects that require 3.3V logic.
This board is fully Arduino IDE compatible and is functionally similar to the Arduino Uno and Nano, but in a smaller form factor. Since it does not include an onboard USB-to-serial converter, you’ll need an external USB-to-Serial adapter (e.g., FTDI or CH340) to upload code.
Its 3.3V operation makes it perfect for interfacing with low-voltage devices such as LoRa modules, nRF24L01, and various 3.3V sensors without requiring level shifters.
