I want to get access to the output voltage from the back of the WZ6012 module. But the pcb is locked pretty tight in there…

Silly question: Is there a special trick to open this thing up?
I want to reach the output voltage preferably from the back or from the side.

Thanks, that’s the one 🙂

Guess it was the J-Link clone that was defect…

Okay, different plan…
I found a J-Link Plus laying around so I’m using that instead 🙂

Can you tell me which chip exactly is used in a WZ6012 (see attached screenshot)?
Also do I need any more information?

Thanks for your help!

Same as my config. I have a newer firmware and software version though.

>> Use external power for WZ device as usual. Do not connect power via the ST-link. Update your ST-link firmware.
I did all that – maybe the ST-Link is broken? But then it wouldn’t have been recognized by the STM32 programmer in the first place…

I bought this clone from china 🙂

I can’t manage to connect to the ST.
Is there a way to hold the device in reset while connecting?
