UART (Universal Asynchronous Receiver/Transmitter) is the most important connection on a flight controller. It’s a hardware serial port used to connect external components such as radio receivers, video transmitters, GPS, etc. Each UART has two pins: one for transmitting data (TX pin) and one...
This is a commercial solution similar to the DIY “wireless sim box” I made. It works the same way but is put together neatly as a more polished product. It’s essentially an ExpressLRS receiver with a processor that converts the signal and sends it to your computer via USB. If you d...
(expresslrs), and assigned all the controls and switches to the appropriate channels in mixes. all that's left to do now is to bind the receiver in the drone to the radio. this guide explains how to bind expresslrs receiver to a transmitter: https://oscarliang.com/bind-expresslrs-...
If you are getting bad range or unexplained failsafe from your Jumper T16 or Radiomaster TX16S when flying with the multi-protocol module, the problem could be fixed by frequency fine tuning. Here I will show you how to fine tune frequency setting in the radio. Some of the links on this ...

Some people prefer to create a new profile for every single drone they have. But if you have a dozen of models like I do, it becomes a lot of work, and it’s hard to manage. So what I personally do is only create a model profile for each RF protocol, and I bind all my quads...
SmartAudio is a protocol between the flight controller and video transmitter. It’s required to support VTX control. The other protocol is called tramp which is used in ImmersionRC VTX. Being able to change VTX settings remotely is so easy. It might not sound like a great deal, but once I...
