✅ This small module is made for your microelectronics projects with the Arduino IDE. It is equipped with 4 ADC channels 10-bit, 5 PWM pins, 12 DIOS and serial hardware connections RX and TX.
✅ It runs with a clock frequency of 16 MHz and 5 V and has a fixed voltage regulator on board.
✅ On this board all pins are labeled correctly. In addition, the circuit is provided with a PTC fuse and a protective diode.
✅ Please note that an unregulated voltage of over 5V can be created on the connection marked with RAW on the board. Regular 5V voltages can be created directly to VCC.

The AZ-ProMicro-Board is similar to the AZ-ProMini-Board, but has a Atmega32U4 on board. The USB transceiver in 32U4 enables us to add USB connectivity on the board and to do without the bulky external USB interface.


  • The ATMEGA32U4 5V 16MHz Development Board contains a PTC fuse and a diode to protect the circuit circuit circuit. The AZ-ProMicro-Board Development Board is durable, robust and stable. There is also a voltage controller on board so that it can accept up to 12VDC.

Technical details:
