Some good news for those who are looking for a cheap micro brushed FC, and only want to run Frsky TX. I managed to connect a PPM receiver to the Micro Scisky board (aka Quanum Pico).
Our FB Group had a massive argument over this question the other day: is PPM signal analog or digital?
There have been a lot of discussion on using SBUS over PPM for radio receiver. Here we will have a look at the differences and the advantages of SBUS over PPM.
For radio receiver, there are a few output signal formats. The traditional and also most common type of RX signal is the PWM and basically PWM requires 1 cable per channel. PPM is now getting more and more popular, because it can handle all 8 channels in 1 signal wire.
