Once the process is done, a message similar to the screenshot below is shown: While the process is burning the bootloader is taking place, you should see the Arduino Led, the TX Led and the RX Led blinking. Wait for a minute, until the process is done: The last step is to burn the bootloader, by going to Tools and clicking Burn Bootloader. Then we select Arduino As ISP from Tools > Programmer: Now that the Arduino Uno is programmed to be an ISP (ISP stand for Is-System Programmer), we are now ready to burn the bootloader to the Arduino Pro Micro.From Tools > Board, choose Arduino Leonardo: Screenshot below shows that the selected board is Arduino/Genuino Uno and the port (yours could be different): Now, plug the Arduino Uno to the computer, select the port where the Arduino Uno is connected to, and upload the sketch. Then go to File > Examples > ArduinoISP > ArduinoISP. LOADING THE ArduinoISP SKETCH TO ARDUINO UNO

ARDUINO UNO – ARDUINO PRO MICRO CONNECTIONSĬonnect the Arduino Uno 5V pin to Arduino Pro Micro VCC pin (red wire)Ĭonnect the Arduino Uno GND pin to Arduino Pro Micro GND pin (black wire)Ĭonnect the Arduino Uno Pin 13 to Arduino Pro Micro Pin 15 (blue wire)Ĭonnect the Arduino Uno Pin 12 to Arduino Pro Micro Pin 14 (green wire)Ĭonnect the Arduino Uno Pin 11 to Arduino Pro Micro Pin 16 (yellow wire)Ĭonnect the Arduino Uno Pin 10 to Arduino Pro Micro Pin RST (white wire)Image below shows how I connected the two boards based from the connections above:.

The following demonstrates how the bootloader is burned to the Arduino Pro Micro (clone) via an Arduino Uno (clone). It suggested of burning a bootloader to the Arduino Pro Micro via an ISP (a spare Arduino Uno clone in my case). I did a lot of researching, and stumbled down with a thread in the Arduino forum. However, the board wasn’t detected at all, as I could not see the port where the Arduino Pro Micro was connected to.

I wanted to check if the board was still functioning, by trying to upload a Blink sketch into it.

The microcontroller is “ featuring a built-in USB which makes the Micro recognisable as a mouse or keyboard.” Recently, I was revisiting my electronics components and found my old Arduino Pro Micro clone, which has a similar board with Arduino Leonardo as both boards are based on Atmel Mega32u4 microcontroller.
