Does the Gravity: GP8101S work with a rc car receiver that supplies 5v and a pwn signal?

Hey there, @Accounts289149, the [GP8101S module](https://core-electronics.com.au/catalog/product/view/sku/DFR1036) can run from the receiver’s 5 V supply, but it won’t interpret the signal as an RC servo command.

It just converts **PWM duty cycle** directly into voltage. You’d most likely need a small microcontroller between them to measure the RC pulse width and generate a new 0–100% duty-cycle PWM signal. All of them would need a common ground.
