20230614 - Edusat subsystem prototype know errors

Known errors

I soldered some PCB’s and I discovered that there is something wrong, and I dont get why. The know errors are:

  • When the button is pressed there is a shortcircuit 😣. Try removing R3, then it should be solved but the button would not be possible to use. The schematic looks perfect,,,, is it shortcircuit pin 2 and 3 of the ESP32? It seems, it is the only way ground and Vcc are connected when the button is pressed.
  • The SB4 is not correctly placed.
