Blue pill schematic pdf
There's a reset button on the top-right corner for obvious reasons. They don't look too nice but serve the purpose. There are eight vias on the top layer that I could not avoid. On the flip side, the board hosts two voltage regulators, satisfying the 3. I was happy with the ADC sampling rate and resolution but I was using it in its original breadboard setup as I kept postponing a proper build of this rather inexpensive oscilloscope.Īlso on the front side, I placed three buttons and four other header connectors. This was first prototyped about one and a half years ago. Furthermore, it can export both the wave shape and its spectrum in a file on the SD card. Like soldering small inductor in Vbus line?The device was constructed on single-side PCB that features 3 general purpose buttons and various extension connectors. Does is require any work on board side? Infj crush If it is correct or should be any extra connections? If USB type C is connected properly? Thank you. Is it correct or should be any extra wiring? I also want to have SWO pin on that connector. This topic was automatically closed 90 days after the last reply.

You can also think a bit about stuff that comes for free on a PCB. As with any uC controller project connected to a cable that sucks up EMI. Also, have you considered the thermal performance of U1 if you are planning to draw up to 1A from it?
Looking at the original, my pet peeve is the ground symbol being placed horizontal. Everyone should know what it is and clutters up the schematic. I would also hide the reference for gndref. I would call it gnd or gndd but not gndref. Your ground symbol is not actually ground but earthing or sometimes instrument ground. Looks well organized though i would prefer some of the typical circuitry such as the crystal in the typical location next to the mpu. However, the image itself was svg-file, thus can be opened in new tab and scale without problem.

PDF The image of the current schematic is way too small to read. The schematics of the original BluePill are: schematics. The power supply is still under consideration if I need the battery power or rechargeable power or just left as is.
