I am trying to create a custom keyboard, and I was trying to flash my board with stm32f070c6t6 MCU in DFU mode using cube programmer, but I keep getting "no DFU detected" (of course while pulling BOOT0 pin high).Also, every time I plug my device into...

I encountered this error when I was trying to flash my custom board with fresh stm32F070C6T6. I used st link v2 for debugging. I updated the firmware of st link v2 right before debugging. NRST floating, BOOT0 connected to 3V3 -> failed (in any mode)N...

Yeah, I see. I think that's really good advice, and I have made such mistakes before. So I agree that I should ensure everything is actually ok.It might take some time because I have no experience doing it, but I will try.

I removed U5, but it did not work, no dfu detected + USB error not recognized error.I checked the connection between the receptacle pin and MCU pin directly using multimeter, and made sure that they are properly connected. So I think it is safe to sa...

Thank you. So I calculated using the website you suggested, and got 140.4440... This means that I need to probably redesign my board, right?I figured out that by decreasing the height, we can decrease impedance dramatically, but I also found that 0.8...

I searched a little about this and tried to calculate using the KiCad calculator tool. Then I got Zeven: 189.26 and Zodd: 67.822.This is mostly because I designed the board with only 2 layers, meaning that the distance between the ground plane and D+...

Thank you for the info.I used KiCad's differential routing tool, assuming those traces are almost the same length and maintaining close distance, and I also tried to minimize sharp corners and vias.I also tried not to allow any other traces to cross ...
