Arduino Pro Mini Compatible Board — ATmega328P 3.3V 8MHz
A compact, bare-bones microcontroller board based on the ATmega328P, designed for projects where space and weight are a priority. Runs at 3.3V making it ideal for low-power applications and direct interfacing with 3.3V sensors and modules without the need for level shifting. Connects directly to an FTDI Basic Breakout board for programming and supports auto-reset.
Please Note: This board requires an external FTDI programmer (not included) for uploading sketches. No USB connection is onboard. Instructions and technical support are not provided — please ensure you are familiar with this product before purchasing.
