Gillywings Posted November 23, 2018 Share Posted November 23, 2018 Hello, I'm new to the world of PIN2DMD. I set up my Stm32f4 card and everything is OK. I put my license on an SD card. When I plug my stm32f4 into USB on the PC it's OK. If I plug the card into an external USB power supply it is KO. If I plug the card into an external 5v power supply It is also KO. Do you have any idea? Oh yes, I use a PCB from germangaming Link to comment Share on other sites More sharing options...
Rappelbox Posted November 23, 2018 Share Posted November 23, 2018 What do you exactly mean with KO? why didn’t you contact me directly? The pcb I sell is nothing different from the pcb Design provided from github. Kind regards, Dom Link to comment Share on other sites More sharing options...
