In the first, I’m sorry for not recording anything for 3 days, truthfully I have no arguments because it was my laziness, i mad some remakes in the PCB because I knew that i was using the wrong footprints for the diodes, and also I mad differences in the place of the XIAO, and if any of you have any advice for me I will appreciate it, specially an advice in the CAD please because I’m very bad in it.
