Description
Schematics & PCB for battery spot welder controller board.
- Provides simple user interface
- Accepts pedal input ( with smart unintended-weld protection )
- Outputs precisely timed pulses for [high current relay](https://www.banggood.com/custlink/KGDDEpKHCE)
- Very simple to solder, generous spacing and no SMD components
- Easy to remove DIP8 components ( MCU & DRIVER ) thanks to the space below and above sockets.
