Arduino Pro Mini 328 3.3V/8MHz Development Board | ATmega328

The Arduino Pro Mini 328 (3.3V, 8MHz) is a compact and efficient microcontroller development board based on the ATmega328 chip. It is designed for projects where small size and low power consumption are essential.

This version operates at 3.3V with an 8MHz clock speed, making it ideal for battery-powered and low-voltage projects. It offers the full power of an Arduino Uno in a much smaller form factor.

The board does not include a USB interface, so you’ll need an FTDI or USB-to-Serial adapter to upload code. Despite its size, it supports all the standard Arduino features and libraries — perfect for embedded systems, IoT projects, wearables, and compact robots.

Features:

1. Based on ATmega328 microcontroller
2. Operating Voltage: 3.3V
3. Clock Speed: 8MHz
4. 14 digital I/O pins (6 PWM outputs)
5. 8 analog input pins
6. Supports UART, SPI, and I²C communication
7. Compact size for space-limited projects
8. Low power consumption for battery operation
9. Compatible with Arduino IDE
