🔧 FTCBlock Pro Micro ATmega32U4 Module Board for Arduino Leonardo: 5V/16MHz, PIN Header, ATmega328 Pro Mini Replacement - Pack of 3 Review

Used for mechanical keyboards. All 3 worked fine. I reinforced the ports but they didn't seem to be weakened or anything. I think the colors of the LEDs are different than the "real" Pro Micros, but that was fine. The edges are a bit sharp, be careful. Would buy again.

I (and others, read the reviews) had issues with the micro USB connector detaching and popping out of the circuit board. I've bought these micro-like Arduinos from several different vendors on Revain, and in my experience all boards should be made in the same factory and share the same potential fault. It seems there was a large batch where the USB connector was badly soldered. Plugging and unplugging the USB cable multiple times can cause the connection to fail or actually push the connector…

Removed 2 stars as J1 is bypassed by the factory soldered bypass. The board and OLED screen were killed by trying to put 7V on the RAW pin. I installed a board from another seller that has J1 unsoldered and it works fine.

Nice clone of Arduino Pro Micro by FTCblock. The board comes in an electrostatic bag along with two rows of pins that you can solder or not. . The Arduino Pro Micro requires a micro USB cable to power/program the board, which is not included here. Any Micro USB cable that can transfer data will work (e.g. an Android OTG cable). The micro USB socket on the board provides a strong, reliable and secure wired connection unlike many other cheap Arduino clones. additional drivers or special…

My mistake. I asked an electrical engineer to look at my work and I made some serious mistakes that resulted in the chip being bricked. I will buy it again and take care!

This worked twice when running the Blink sketch, after which the COM ports were not detected on the Raspberry Pi or the Windows computer. Right now it's a $6 briquette.
