An updated version of the previous RC boat motor driver, this time with schematics and PCB design for Cmos output.
Slight changes made to software to improve performance, and to correct a smal bug that could stop the PWM working but in practice did not !
The software was written for Pic 16F684 but can easily be adapted for other pics with PWM. Osc. was configured for 4 Mhz.
A Targa PCB file is included, containing the circuit and PCB. The PCB is designed as a singlesided board with surface mount components (30 mm X 30 mm), One can of course change the design for throughhole boards.

Note: the board includes a LDO 5 Volt regulator as a BEC for the receiver.
The motor driver has a maximum current capability of 9 Ampere (with appropriate heatsinking).
If double sided PCB is used and the Cmos transistor heatsinked on the unused copper side, then the unit is quite capable for sourcing over 1 ampere which is adequate foe most 12 volt model boar motors. As stated a higher current can be achieved with extra heatsinking. As I have not carried out measurements with extended heat sinking, I would advise that if you require the extra capacity that you add a heatsink and then gradually increase the current to establish if the cmos reamins within reasonable temperatures. Do not fully load the circuit until you have made this test or you will surely destroy the Cmos.
Important addition in case you don't spot it: If you use double sided board, then make sure you use a drill etc. to clear around the component leg holes on the copper side where the resistor and cmos are mounted , or the legs might short out!

RC pulse driving DC motor for model boat etc.

The software checks the pulse length and then sets the PWM output to suit. The PWM output is then used to drive a DC motor via a transistor or FET of suitable power rating. A port read was used to detect the pulse width and this method is not very accurate, however it is sufficiently accurate for this application, and works very well for my models.
