The BMT Pro Micro 5V/16MHz is an advanced, compact, and versatile Arduino-compatible development board that uses the ATmega32U4 microcontroller. Unlike lower-cost alternatives that use the ATmega328P, this board integrates a built-in USB peripheral, eliminating the need for bulky external USB interfaces. It's ideal for hobbyists, makers, and electronics developers who need a small, powerful, and fully USB-capable microcontroller board for their projects.
Overview
This tiny board packs impressive functionality in a small form factor. It offers:
- 16 MHz clock speed and 5V operating voltage for consistent Arduino performance.
- 4 channels of 10-bit ADC, 5 PWM pins, and 12 digital I/O pins for versatile project integration.
- Hardware serial connections (Rx/Tx) to easily communicate with other microcontrollers or modules.
- Onboard USB connectivity thanks to the ATmega32U4, making it perfect for direct USB communication without additional adapters.
Power and Voltage
The BMT Pro Micro comes with an onboard voltage regulator. The RAW pin can safely accept voltages up to 12V (absolute maximum), though 9V is recommended for long-term stability. The VCC pin provides regulated 5V output, and must never be supplied with 12V, as this may damage the board.
Key Features
- Fully Arduino-compatible and programmable using the Arduino IDE.
- Small footprint, perfect for compact, wearable, and portable projects.
- Integrated USB for programming and communication.
- Multiple analog, PWM, and digital I/O pins for versatile hardware interfacing.
- Suitable for robotics, IoT, sensors, LED controllers, and general prototyping.
