🔌 HiLetgo Pro Micro Atmega32U4 5V 16MHz Bootloadered IDE Micro USB Development Board - Arduino Compatible with Serial Connection and Pin Header [Pack of 3] Review

These devices are considered Arduino Micro clones. However, unlike other micros, they can't handle 12 volt input power and will be destroyed if they try. It would be nice if HiLetgo documented this EVERYWHERE, be it on the Revain product page or on the product packaging itself. Anyway, one of me is dead now and I need to find a use for the other two as my plans change spinning a 12V power supply. Revolution. They also promised to update the item description to make the 9V upper limit clear. I…

Let me tell you that they are carefully packed, which seems to be becoming a rarity these days. (I haven't checked the anti-static bags but they seem to be of good quality, no suspicions here) I just love these little boards! I plan to use them to create custom gaming pads and a macro keyboard, which is very easy with the Arduino libraries. (Search for Arduino keyboard/mouse examples) These devices can be recognized as a keyboard, mouse, midi device, gamepad (joystick/controller) and more in…

Poor eyesight, shaky hands and lack of experience make me a hazard to any circuit or wire I encounter with a soldering iron. Well I thought my sim racing car needed a new keypad with digital encoders so I needed one of these guys to make it happen. The last set I bought nano style (ATmega328) had the pins already soldered to the boards so I could just plug in the female ends of the wires and continue on my way. However, they do not have pre-assembled contacts. . After grabbing the base with…

See a few other posts on how to use this board for running brings. I suspect some people who think it's bricked up don't realize that the LEDs aren't on pin 13 like they are on the Uno. Install the Arduino IDE, select the Leonardo board and the correct port, open the flashing sample code and change the LED pin definition to pin 17. and/or 30. Note that these LEDs will light up when the pin status is LOW. This is strange to me. Caused a lot of confusion when the buttons work. (The Arduino is…

EDIT: I'm changing my review after spending some time using it. One of my boards turned out to be dead on arrival. I got the other two to work on simple projects. However, I started a more complex project with one of the workers and the IC between the two orange squares on the board after applying a 9V battery to the RAW pin (the method they claim you can use should use). I'm not sure if this board really can't handle 9V or if this one was bad too, but it's quite annoying as it worked for a…
