pcb design

  1. Technical Discussion
    Good day~ I currently have a project in a vehicle in which I want to replicate a small button PCB board with my own buttons using resistance values for the circuit so the car knows which function to activate. I have already learn some PCB design knowledge from website...
  2. Batteries and Charging
    Should I buy a 4S PCB? And would it have to be rated for 66A continuous discharge, if the most I'm ever using is 30A ?
