Some of those may have operated at 27mhz. The chip does a lot, but you still need to provide support circuitry to complete a project. Sign up now to remove ads between posts. If anyone could point me to any electronic schematics or any useful information in general, I would be extremely appreciative.

Even though it makes my job much easier, I would also prefer to be making the eatasheet circuit without using an IC that does everything for me: May 04, Images View all Images in thread.

Here is the companion data sheet for the LM transmitter chip. Welcome to the forum. Return to DIY Electronics. It works in conjunction with a companion transmitter chip, LM, lj provide four channels of control. The Arduino boards can also do that. So, there is not real schematics, but only programming examples. Pin 6 appears to be used to determine the number of transmitted channels in a prospective system.

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.

Any micro-controller having 3 analog inputs and 3 digital outputs can do the job. These devices are well suited for use at 27, 49 or 72 mhz. Does it even matter what value they are?

Mogrel So, there is not real schematics, but only programming datashest. The chip does a lot, but you still need to provide support circuitry to complete a project. I found a few circuits, but I am a bit unsure about datasheeet usage of these ICs. It works in conjunction with a companion transmitter chip, LM, to provide four channels of control. Does it even matter what value they are? Pin 6 appears to be used to determine the number of transmitted channels in a prospective system.
