We are having trouble figuring out how to send PWM signals and differentiating motor inputs without the need of an Arduino or more microcontrollers or ESCs using the H bridge we have. Any advice/ input would be appreciated. We soldered pins to the H bridge to use with breadboard. Also soldered cables to each brushed motor.

Module we're using:

Radio controller we're using: (planning on using mixed control)

Any advice/input will be greatly appreciated. Thank you.

You could also simulate a PWM signal using a 555 timer. See ...

Experience is what you get when you don't get what you want.
