## Description

Compact board for Arduino projects with Atmega328P at 16MHz, ideal for prototyping and automation where space matters. It is programmed by external programmer via TTL-USB, powered on the RAW pin at 5-12VDC with integrated regulator, offers 14 digital pins, 8 analog and 6 PWM outputs for sensors, controls and actuators.
PRO MINI 5V development board, compatible with Arduino IDE. The board requires a programmer to be programmed. Power is supplied to the RAW pin with approximately 12VDC voltage.
If the board cannot be rewritten, follow these steps:
- Disconnect the programmer with the Pro Mini board from the PC.
- Press and hold the RESET button.
- While holding the button, connect the board to the PC.
- Keep the button pressed and upload the code.
- When "Uploading" appears in the Arduino IDE, release the RESET button.
