I found a few circuits, but I am a bit unsure about the usage of these ICs. Remember Me Forgot Password? Posting Quick Reply – Please Wait.

Datasheet «LM1872»

Theory of operation and suggested circuits are provided in both data sheets. What do you use as HF transmission? Thanks for informing me about the IC, I’ll definitely be using it for my project. Welcome to the forum. Something like this datashheet, and shop?

Thank you for your quick replies! Originally Posted by Magranon I have no idea what the values of B1, B2 or B3 are, nor is it mentioned anywhere daatsheet the website the image came from. Sorry if this is a newbie question, which it probably is. Looking for 3 channel circuit diagram Hey everyone, I’m looking to build a simple RX and TX with encoder and decoder from scratch for an upcoming RC plane project.


So, there is not real schematics, but only programming examples. Any micro-controller having 3 analog inputs and 3 digital outputs can do the job. Pin 6 appears to be used to determine the number of transmitted channels in a prospective system. P Having clocks in the circuit would be fine though.

Radio Control Receiver/Decoder

Looking for 3 channel circuit diagram. It works in conjunction with a companion transmitter chip, LM, to provide four channels of adtasheet. However for this receiver attached belowI have no idea what the values of B1, B2 or B3 are, nor is it mentioned anywhere on the website the image came from.

Does it even matter what value they are? Last edited by Magranon; May 04, at Here is the companion data sheet for the LM transmitter chip. Even though it makes my job much easier, I would also prefer to be making the whole circuit without using an IC that does everything for me: I’ve been searching for many hours and have yet to come upon any feasible circuits. These devices are well suited for use at 27, 49 or 72 mhz.

Bruce Abbott We want May 06, If you must use discrete components, look up some old Heathkit radio control circuits. Last edited by whitecrest; May 04, at I’m assuming this forum is the right place to ask these kinds of questions, but if it isn’t I apologize. The only criteria of the build are that it should preferably have 3 channels and that it must be able to control the rotation of two servos and the speed of the main motor.
