Frsky XSR - the best miniquad RX?

When it comes to RC gear, we realy like FRsky gear, feature packed, reliable and very affordable. So its great to see that there is a new mini reciever in town, the Frsky XSR mini receiver which has been designed to be small and lightweight (3.8g) to work well with your FPV racing quadcopter! As the same suggests the XSR is part of the X-series receivers (S.Port Telemetry) from Frsky.

FRsky XSR Receiver

To keep the receiver small, Frsky have done away with all of the pin headers to connect your servo cable to, and a tiny 5 pin connector is included. Despite this tiny size the XSR has a Smart port telemetry pin, CPPM out pin and also SBUS out pin.

FRsky XSR Pinout

You can think of the XSR receiver as a scaled down version of the X4R receiver which is currently very popular among miniquad pilots. However for any drone/quadcopter builds I am convinced that the XSR will become the new most popular RX on the market.

If you only need 8 channels you can hook it up via CPPM mode. If you need 16 channels you can hook it to your autopilot system via the SBUS pin.

EU LBT Firmware

If you order your XSR from Europe you will most likely get the LBT firmware version. This ensures that the device complies to EU regulations and you will need to also use the latest LBT firmware on your Taranis radio. When binding set your Taranis to D16-LBT mode.

Connecting XSR with your Naze32 / Flip32 / Spracing F3

Because of the limited number of UART ports available on the Naze32 (and related autopilots) we suggest you use CPPM mode. So all you will need to do is connect the 5V, GND to the

XSR-Naze32-connection

The green wire from the XSR is the CPPM wire, so it will need to be soldered onto R/C input 1 on your Naze32 board. Similarly the Ground and 5V pins go to the corresponding R/C input locations on your naze32 flight controller. For more information please check out the XSR Manual.

So there you have it, if you have any questions please ask below and if you want to buy one it would be great if you purchased from us over on Unmanned Tech Shop XSR.
