SBUS + S.Port Receiver wiring:
The XILO FC supports these Receivers:
• SBUS
• SBUS+S.port
• F.port
• DSM2 Receiver
•  Crossre
Thesereceiversarenotsupportedanymore,ifyouneed,withpatchedrmware,itcouldbeused:
• Stand PWM receiver
• PPM receiver

Wiring - ESC
4in1 ESC
Single ESC
• The XILO 4in1 designed to support TLM(RPM/Voltage) and Current ADC, the Current Scale should be setted to 118
• If the ESC supports TLM function, please connect all 4 ESC TLM wires together, solder on the TLM pads
• If you are using PDB with current sensor(analog ADC), connect to the Curr pad

VTX Power Switch Setup
• The XILO Stax flight controller features a power pad for your video transmitter that can be remotely controlled via a
switch setup in Betaflight. This allows you to remotely turn your VTX on or off from your radio! Simply solder your
VTXtothecorrespondingpadsontheStaxFC,(VTX,S/A,PWR,GND),thePWRpadwillprovideyourVTXwithltered
VBATT power. By default, the pad will be powered on. Go into Beta to set up a switch if you want to control power on/
offremotely.Youwillnditunderthe"Modes"taband"USER1"switch.AssignthistotheAUXswitchofyourchoiceto
turn the power on/off for that PWR pad. Easy!
