High Power DC Motor Speed Control PCB patterns (PDF download) [11112161/2]
PDF with the PCB designs for Our biggest-ever DC speed controller: 12 to 60V at up to 40A (double-sided).
Both layers of both PCBs are in a single PDF. This include the main PCB, coded 11112161 and the Mosfet PCB, coded 11112162.
Note that due to the number of vias, this would be difficult to etch at home so it is mainly provided as a reference.
