STM32F051R8T6 Voltage Problem

HChen.23 · ‎2020-01-20

Recently, I had a strange problem when I used the stm32fo51r8t6 board from the previous class. I tested the 5V and 3V pins in it, but there was a module that can supply me normally (3V normal, 5V) Not long), I would like to say if the students who have attended the class have encountered similar problems before, can they do related exchanges, or can the teacher have relevant experience to share.

Pin at 3V

Pin at 5V

What class? What exactly is the problem? What is on that small black board, and which color wire is connected where?

Dear waclawek.jan,

small black board is a component. The orange line is Clock Control, black line is Data Control & grown line is ground. Two Picture connect same just 3V & 5V on green broad different place.
