Solid-state motor drivers
You have received a new message from Spike Spencer.
See my recent addition to the forum. If you wish to adopt my PIC signal-conditioning board, I can let you have (at component cost) either a completed board with loaded PIC for experimentation, or just the circuit diagram, PCB mask and the code (Picaxe BASIC) listing.
For serious power, DE do a 65 Amp driver ! (but you will then need larger batteries)
