1537 MCU not Working!
« on: September 21, 2020, 08:14:13 AM »
I still having a problem with my MCU board.
The controller don't turn on with the MCU, in TP6 and TP10 I don't have the 3.3v, and the traces are ok.

TP6 and TP10 on the 1537 MCU board are on the data/control lines between the MCU and the RF module. Check R9 and R10 (both top side of MCU board) they should measure 33ohms. If those are good, then the MCU or RF module has the issue.

Screwing up is one of the best learning tools, so long as the only thing you're not learning is how to screw up.
