The Frsky R-XSR receiver is the smallest RX that can do 16 channel SBUS and SmartPort telemetry. It’s the go-to option now and replaces the XSR or X4R-SB for Frsky TX users who own a Frsky transmitters such as the X9D and QX7.
I will show you how to flash Frsky receiver firmware on your R-XSR, R9 Mini, XSR, D4R-II, X4R-SB, XM+ and some other RX. Updating RX firmware is useful when you have the wrong firmware that prevents you from binding, and getting the improvements and bug fixes in the latest firmware.
FrSky XSR-M is a smallest SBUS/CPPM Radio Receiver offering full range and Smart Port telemetry recently released.
The XM+ radio receiver is a tiny SBUS diversity RX from Frsky. It’s insanely light weight making it a great alternative to X4R-SB and XSR RX for micro quad builds. In this post we will show you the features of XM+ and how to use it.
A new Frsky receiver option for light weight and tiny mini/micro quad builds – the Furious Mini RX! It’s even smaller than XSR!
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.
