AITRIP 5 PCS Pro Micro ATmega32U4 5V/16MHz Module Board with 2 Row pin Header Compatible with arduino Leonardo Replace ATmega328 Pro Mini (5PCS)

Got this to batch enroll chromebooks for my school. The work perfectly for that. I did see other reviews mention the usb breaking off, and when I got them I noticed very minimal solder on the two points that are used for grounding and structure. I added some solder and it was no problem. Frankly most people using a device like this will have some skill with soldering, but I'm knocking a star for that

I purchased these as an alternative to some other older micros i had that did not have the micro usb connector on them; thinking this would speed ip my assembly process. I was incorrect on this idea. I bought a pack of 5. Tested and started building with a few of them. Attached a reset button to one I was going to flash and after plugging in the cable, the connector broke clean off the board. Being careful that these are tiny bits, this shouldn't happen the first few times the cable is connected. I could understand this happening with rough use or many connect/disconnects but in this case we are talking 3 times a cable was plugged in to this board, and on the third time it was a clean break.Solder on the pads isnt there for all 4 legs off the connector and only one ground pad was soldered.I cannot recommend these to anyone else for that alone.To top it off, 2 of the 5 boards i ordered came DOA; one corrupted and not able to be flashed at all, and the other with an internal short to a ground pin.Seriously dont order these; theyre not what they appear to be and are of very very poor quality.

No schematic available for the board - and it does not match any other Arduino MicrosAnd it is dead - alive just enough to report that the Device ID is wrong.Completely unusable.

The USB connector breaks off easilyIt may not work the first time!THIS IS JUNK!! DON'T BUYDon't buy if the USB connector isn't solder to the underside of the boardIf you don't see the USB solder post on bottom of the board. DON'T BUY!!Check underside pictures, if there is not bottom pictures ,DON'T BUY!!JUNK<JUNK< JUNK!!!

Some work, some don't. These have cost me over 200 dollars just on return labels not including the costs of the board itself. Would not recommend. I've got about 10 broken boards out of the 40 I've bought
