An Awesome New Open Source Long Range RC Transmitter
An Awesome New Open Source Long Range RC Transmitter
Arduino Team — January 30, 2023
DSM (Digital Spectrum Modulation) is a relatively new radio control technology ideal for long range applications. It uses two methods, FHSS (Frequency Hopping Spread Spectrum) and DSSS (Direct Sequence Spread Spectrum), to transmit data, the latter being particularly resistant to interference and therefore suitable for transmission over long distances. If you want to take advantage of DSM for your robotics projects, James Bruton has designed an open source transmitter that you can build.
Bruton makes a lot of remote-controlled robots, so he needed a good remote. His previous designs, while full of great features, didn't have the kind of range he wanted. He therefore created this new remote control which incorporates DSM transmission technology. It contains two DSM transmitters to operate 20 individual channels. It uses these channels for four joysticks (each with three axes), four toggle switches, and four momentary push buttons. Together they are enough to control even the most complicated robots.
Inside the remote's 3D printed enclosure is an Arduino Mega 2560 board. It monitors various commands and transmits data to a pair of OrangeRX 2.4GHz DSMX transmitters. It also displays battery voltage on a small three-digit, seven-segment display. Power comes from four 18650 lithium battery cells. This remote will work with any compatible DSM receiver, which is affordable and easy to integrate into a project, as it works like a standard RC receiver.
