Well, I broke my second connector. The first was because I used it as leverage taking it off the breadboard. Doh! The second was a spectacular backflip when the USB cable wrapped around my leg to get up. Not a design problem. BUT, I now have two bricked Pro Micros. Is there a way to rescue these guys? I can’t see any traces left (all plastic) to be able to solder to. I’ve seen how to program the Pro Mini’s via another Arduino, but I can’t seem to get this work on the Pro Micro. Is there a different trick with these guys?
If you post pictures, I might get a better idea of how to help.
You can program them using an AVR programmer, but you will never again be able to program them over USB Check out the tutorial below for instructions on how to install an Arduino bootloader or other code to another Arduino (see top comment for instructions on using a Pro Micro, the SPI pins are in a different location).
Hmm. I knew the USB wouldn’t work. I was so hoping that was going to work. I knew that the Micro was somehow different. Still have an issue. One ProMicro shows no yellow LED when burning bootloader or sketch, so I guess that guy is toast… The other one shows all sorts of activity, but will not run the sketch. I was able to burn a bootloader and sketch, but it won’t run. Either it’s me or these things are toast in different ways. Since I was able to burn a loader and upload a sketch, I am assuming that because I can upload, I have it hooked up correctly? I am definitely running the arduino as an ISP sketch on the UNO and have the correct board and speed selected. Here’s the connections:
D14 (MISO) → UNO D12
D16 (MOSI) → UNO D11
D15 (SCK) → UNO D13
VCC → UNO 5V
GND → UNO GND
RST → UNO D10
BASIC, BASIC sketch, it was from the ProMicro Blink, then I also just did a D5 on and off with a 1000ms delay. Nothing. But it will light the red (power) and the yellow (near D7) when booting / uploading…
Tell me I’m doing something dumb…
