Teyleten Robot 3pcs Pro Micro Atmega32U4 5V 16MHz Bootloadered IDE Micro USB Pro Micro Development Board Microcontroller Compatible to Arduino Pro Micro Serial Connection with Pin Header

Yes, this is a Leonardo, which IS a Pro-Micro, but with more pins. The fact that we can't downvote the reviews that are complaining about his is ridiculous. Board works great, flashes very fast. Only downside is the lack of documentation and pinouts, but if you search enough you can find them. Besides the screenprint on the board here is more pin info. Note that the pinouts on the board are NOT in order, so take notice. I'll go down the left side of the board. I'll list the board description along with features. When you see just a number, that's a digital IO TX0 - 1 (this is "digital pin 1") TX1 - 0 GND GND 2 - SDA - A4 3 - SCL - A5 - PWM 4 - A6 5 - PWM 6 - A7 - PWM 7 8 - A8 9 - A9 - PWM on the right side of the board, going down RAW GND RST VCC 21 - A3 20 - A2 19 - A1 18 - A0 15 - SCLK 14 - MISO 16 - MOSI 10 - A10 - PWM

These worked just fine after some cable trial and error. Not all USB cables are created equally so if your new card doesn't respond when plugged it, try a different cable (preferably one that came with a phone). Once recognized by my PC everything worked as it should!

It is my go to for most things I need. It compiles and loads fast. I use it to automate mouse and keyboard tasks. It is the first thing I grab to test peripherals because it seems faster to use. I bought this after trying the USB-C version (because I'm used to the micro USB and expect the USB-C to replace it eventually). ADC behaves differently but did not spend time to understand the difference; it was a problem for something I was trying. The USB-C is harder to insert and remove. So I bought three orders of this in case the micro USB is no longer available.

Bought this for my weekend projects. Lowest price on Amazon for this kind of arduino. Received package as shown on pictures. This is 5V board. So far tested in project as a HID Keyboard and as an I2C controller. I had some issues setting this up on mac. Restart, reinstall of Arduino studio solved the issue. No issues on Linux.

This is a good cheap Arduino clone. It worked well for my use case (daemonbite controller adapter), but unfortunately the micro usb plug ripped off with very little pressure applied to it. I knew this was a possible issue when purchasing and was trying to be very gentle with it, but it still came off. Still a good product for the price but something to watch out for.
