Radio Control Circuit Design
How can I build a simple 2 channel radio controlled circuit?
I am wanting to build a small radio frequency circuit, much like the type you would find in a ‘micro’ rc toy car. It is for this project I’m wanting to do, but I’m having trouble getting started with it. These toys use an RX chip that controlls the speed of the motor and the direction of the car. I have a lot of experience designing and fabricating circuits, but not so much rc circuits. The size of the remote control does not matter, but I need the receiver to be as small as possible. The only thing I was thinking of doing was gutting the RX chip from a toy car and designing a pcb that only includes two channels and the antenna. If you have any schematics, that would really help me out.
all this was available freely years ago.20+yrs, hard to find now.
Good luck ,sorry.
Look up old circuits ,if you want it from scratch.
Else you have a edge on me of new chips ,(likely as done this for 30+ yrs).
Need to contact manufacture engineers to simplify design that they already worked out.
No need to “reinvent wheel” you understand.
look it up.
