Thank you for your quick replies! Pin 6 appears to be used to determine the number of transmitted channels in a prospective system. I found a few circuits, but I am a bit unsure about the usage of these ICs. 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 have no idea what the values of B1, B2 or B3 are, nor is it mentioned anywhere on the website the image came from.

The Arduino boards can also do that. May 04, I’ve been searching for many hours and have yet to come upon any feasible circuits. P Having clocks in the circuit would be fine though. I’m assuming this forum is the right place to ask these kinds of questions, but if it isn’t I apologize.

Return to Datashee Electronics. Bruce Abbott We want Images View all Images in thread. Files View all Files in thread. Something like thisand shop? Sorry if this is a newbie question, which it probably is. However for this receiver attached belowI have no idea what the values of B1, B2 or B3 are, dataasheet is it mentioned anywhere on the website the image came from. What do you use as HF transmission? Here is the companion data sheet for the LM transmitter chip.

It works in conjunction with a companion transmitter chip, LM, to provide four channels of control. May 06, Sign up now to remove ads between posts. Does it even matter what value they are?

Even using the IC, it should provide plenty to do.

Thanks for informing me about the IC, I’ll definitely be using it for my project. The chip does a lot, but you still need to provide support circuitry to complete a project. Some of those may have operated at 27mhz.

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.

Remember Me Forgot Password? These devices are well suited for use at 27, 49 or 72 mhz. Posting Quick Reply – Please Wait.

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. 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. Welcome to the forum. Looking for 3 channel circuit diagram.

If anyone could point me to any electronic schematics or any useful information in general, I would be extremely appreciative. Theory of operation and suggested circuits are provided in both data sheets. Last edited by whitecrest; May 04, at Yeah, forgot to state that I’m looking to be using 27mhz for the build.
