honestly sir I watched hundreds of videos and tens of webpages but this was THE BEST piece of knowledge in the best understandable form I saw on the internet THANK YOU VERY VERY MUCH, love from India, keep it up.
great thanks for your video. i just go a flywoo with f405 pro chip, and I am confusing where should I put my elrs receiver. in manual book tell me need 5v and UART 4, but 4 only have 4.5v another story is, I go information from another video said, the elrs receiver will power on when I plug in USB to my computer. so combine the information, you mention 4.5 and 3.3v are low amp and power on... now I have more confidence to continue my semi-first drone..
I had no idea you can get these boards. Do you use rc receiver outputs for inputs to these boards? I'm using rPi's for different things, this sounds like a fun project!
Hi thanks for the comment and questions. Raspberry Pi are great little boards to work with, but they are much more general in purpose. The boards in this video are designed for one primary purpose - remote flight control. These boards are most commonly used on quadcopters and slightly different variations are used on rc airplanes (mostly it is pin layout). They have standard UART control, so it is possible to connect components to them (GPS, RC receivers, video transmitters, etc.) As you saw in the video, there are other connector types as well (I2C being one) as well as multiple voltages available for external components. The most commonly used opensource flight software for quadcopters is Betaflight. It is designed more for free flight and racing. If you are interested in more programmable flight (return to home, position hold, waypoint missions...) then INav is the firmware you'd be looking at. They are close cousins; they just focus on different flight styles. Betaflight is only designed for "XXcopters" (tri, quad, hexa, octo); however, INav is designed for both copters and fixed wing aircraft.
