We have seen a lot of radio controllers on this channel till now. We’ve seen one using the NRF24 module and making the entire board, weeks back we had the controller made with the HC 12 radio module and a gyro control, but today I have a one of the simplest radio-controller.

This board use a 433Mhz radio connection and an ATTINY 85 chip, so everything is very simple. It has only 4 “digital” channels so we can’t really use it with drones for example. But we could connect anything to these 4 digital outputs. The design is simple and very cheap, just a few dollars.”
