This is a DIY project to send sensors telemetry for a fraction of the weight and cost of the stock sensors. It adds support for several ESC telemetry protocols.

• Frsky Smartport
• FrSky D
• Spektrum XBUS
• Spektrum SRXL
• Spektrum SRXL2
• Flysky IBUS
• Futaba SBUS2
• Multiplex Sensor Bus (MSB)
• Jeti Ex Bus
• Hitec
• CRSF
• Sanwa
• Hott
• JR DMSS

• ESC
  • ESCs with serial telemetry: Hobbywing V3/V4/V5/FlyFun⁽¹⁾, Kontronik⁽²⁾, Kiss (APD F, blheli32, Summit X), APD HV/UHV, OMP M4, ZTW
  • ESC with PWM signal or phase sensor
  • ESC Castle Link
  • Specktrum Smart ESC & Battery
• GPS serial (NMEA)
• Vario (I2C sensors): BMP180, BMP280, MS5611
• Analog sensors: voltage, temperature, current, air speed (MPXV7002)
• Fuel meter (PWM pulses)
• Fuel tank pressure (I2C sensor): XGZP68XXD
• 6 switches (gpio high or low)
