 | | Re: Increasing current output to motors on HandyBoard
|
| Howdy, My original suggestion was to use *solid state* relays. They don't have any contacts. I use them plugged right into my Rug Warrior board at the motor output ports (would work the same on my Handy Board, but I have it on a smaller base, and (...)

| Haven't actually tried it, but I was thinking of the same sort of thing. Use a FET for PWM and a DPDT relay for direction. practically speaking, if you only switched the relay when the FET was off, no power transition, etc.... If your 'bot moves (...)
