Review on 🔧 HiLetgo PRO Mini Atmega328P-AU 5V/16MHz Development Board with Bootloadered Microcontroller and Pin Headers – Pack of 3 by Chris Lentz

Just received this order. Programming connector soldered on and was able to load the program into the Mini. As soon as I had soldered the other connectors (and I've been soldering for almost 60 years), the board fell into disrepair. The downloaded program doesn't run and I can't program the board. LED "Pin 13" does not light up after adding headers. I was getting a little nervous about the electronic boards I bought from Revain, I had some that just didn't come out of the box.
