HiLetgo ST-Link V2 Emulator Downloader Programmer STM32F103C8T6 STM8 STM32 with Cable (Random Color)

Q: I got one of these and updated the firmware. After that, it worked for 2 days and now it won't return a device descriptor. Is that common?

I updated both units I have with no issues.

Q: How do you get the pcb out of the case? i want to check pinouts on the silkscreen vs. the case. thank you...

Based on others who have opened the case...the silkscreen is accurate for Hiletgo . This was the case for mine even those it was reversed from the picture. So I chose not to open the case and trusted the markings with good results. HiLetgo has several manufacturing batches ...but the markings match the hardware it seems.

Q: Can someone tell me what exactly these are for? Can i reprogram an electric scooter?

Used mine to reprogram my frsky R9 module
