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
• The XILO 4in1 designed to Control the VTX power via IO PB1(B01)
