Perfect for compact projects
This board is incredibly small yet powerful. The native USB support makes it easy to emulate keyboards and mice. Great for custom macro pads.

Arduino compatible and fast
Flashed immediately with the Arduino IDE. The 16MHz speed is perfect for my sensor logging project. Highly recommend for students.

Good value but pins are tight
Works exactly as described. The only downside is the pin spacing is very tight, so soldering headers requires a steady hand. Otherwise, excellent performance.

Best Pro Micro clone I've used
I have bought several of these for various drones and controllers. Consistent quality and the bootloader works every time without issues.

Confusing at first
The board works well once you figure out the driver installation on Windows. Documentation could be better for beginners, but it's a great learning tool.
Q: Is this compatible with the Arduino IDE?
A: Yes, it is fully compatible. You just need to select 'Arduino Leonardo' or the specific Pro Micro board definition in the board manager.
Q: What is the maximum current draw from the VCC pin?
A: The onboard regulator can typically supply up to 150mA. For higher current requirements, please power your peripherals externally.
Q: How do I enter the bootloader if the code crashes?
A: You can enter the bootloader by connecting the RST pin to GND twice quickly within 500ms, or by holding the reset button while plugging in the USB cable.
Q: Does this board come with headers pre-soldered?
A: No, this board typically comes without headers soldered to allow for flexible mounting options. You will need to solder them yourself.
Q: Can I power this board with 3.3V?
A: This specific model is the 5V/16MHz version. While the ATmega32U4 can run at 3.3V, this board's regulator and components are optimized for 5V input. We recommend using the 3.3V variant if your project requires it.
