Frsky XM+ Micro D16 SBUS Full Range Receiver Up to 16CH for RC FPV Racing Drone
This insanely tiny 2.4GHz diversity receiver is the next big thing in miniaturization of racing craft. Weighing in at under 2g, this receiver is perfect for those racers who are looking to lower their AUW. These are rated to "full range", so identical to your X4R and D4R setups.
Dimension: 21.5*12*3.5mm(L x W x H)
Number of Channels: Up to 16CH from SBUS (1-15ch for PWM,16ch RSSI for FC)
Operating Voltage Range: 3.7~10V
Operating Current: 30mA @5V
Operating Range: Full range
With RSSI output on board: Analog 0~3.3V
Compatibility: FrSky D16 mode
1. It is a full range receiver, similar range to X4R-SB and XSR, Much smaller size and lighter weight
2. It's possible to direct solder RX to FC with header pins without wires (if FC supports it)
3. XM+ is even smaller than the LR1000 by FuriousFPV, great RX option for their micro quads (such as the Moskito70)
4. Only downside of XM+ RX is the lack of S.Port full telemetry (Smart Port), there is only RSSI telemetry. RSSI has a dedicated solder pad and it¡¯s also available on the 16th channel.
5. RSSI pin outputs PWM signal (0-3.3V). Please be aware that this signal should not be connected to MinimOSD directly, as it will give you 0% or 100% only. You will need a digital to analogue converter (low pass filter) to convert PWM to analogue voltage level.
However the XM+ can output RSSI through Channel 16, so in Betaflight/Cleanflight should be set to use CH16 for telemetry signal and limit aux channels to 12
Frequent asked Question and answer:
RX is bound, but not getting signal in FC
One common problem getting SBUS to work: RX is bound to TX (solid LED on RX) but not getting signal to FC (no activity in receiver tab).
Make sure TX is in D16 mode
Some FC has built-in SBUS inversion, some don¡¯t. Try setting SBUS inversion on or off, it normally fix it.
set sbus_inversion = on, and save.
