PWM Control

Uses 3 Radio Channels to drive 2 motors and 2 switches.


Description

New : There is a simpler and cheaper relay version that doesn't uses the H-bridge IC.

New : It is possible to use it with the Discrete H-Bridge that doesn't uses the H-bridge IC.

Simpler relay version

This is a "simpler" version that does not uses an H-Bridge to invert the engine rotation wise. The software and the PIC circuit are the same.
If you need to reduce the ON resistance, the circuit shows an option with parallel Mosfets. In the parallel option, you should use proper clamped Mosfet.

Discrete components H_Bridge

Circuit

This is a (never tested) discrete components version of the H Bridge that can be used with the Twin Controller to drive two brashed engines.
