The Pro Mini ATmega328P 5V 16MHz is a minimalistic, high-performance microcontroller board built for embedded projects where size, weight, and power efficiency are critical. Powered by the Microchip ATmega328P 8-bit AVR microcontroller running at 16 MHz, it delivers identical processing capability and code compatibility to the standard Arduino Uno, but in a fraction of the physical footprint.
To maintain its ultra-compact form factor and low cost, this board omits an onboard USB-to-UART bridge chip and power jack. Programming is accomplished using an external FTDI programmer, USB-to-TTL adapter (like FT232RL or CP2102), or an ICSP programmer. The board includes an onboard 5V voltage regulator accepting raw DC voltage (5V to 12V on the RAW pin), an 8 MHz / 16 MHz resonator, reset button, and onboard status LED on digital pin 13.
Supplied without pre-soldered header pins, this version gives developers total flexibility to solder custom wiring directly to the board, solder right-angle or straight male/female headers, or integrate the module directly onto PCB motherboards. Operating on a 5V logic supply, it seamlessly interfaces with standard 5V sensors, relays, display screens, and wireless modules, making it a staple for custom IoT nodes, robotics, and flight controllers.
