[Mr.Username]

Thank you!

OK: I don't know what I am doing.
This isn't working.
I seem to be making it worse.
Can some one perhaps AV500 please give me directions forward!
This is embarrassing I have built two working modules.
Thanks!

I have a non working V2 here that someone gave me to look at , it does not power on at all and IC6 (74HCT14) was visibly burnt so I replaced it and still not getting anything when i power it on. The test points for 5V and 3V3 are getting the correct voltage and IC7 (MCU) gets very hot. I was going to replace the MCU but I dont see a file available to flash it? and is there anything else that I should check? I assume it was reverse powered but we dont know the module was donated to an educational organization and that is how they received it.
Thanks

Hi.

I just found out that the required rotary encoders and knobs are also available from mouser, so you don't need to order them extra:

Maybe you could update these in you mouser cart / BOM, simplifies the project a bit



Thanks for the great module VPME and happy soldering to everyone!
