ESC Telemetry

info

The purpose of ESC telemetry is to provide a method of reading the values provided by the ESC. These are things such as RPM, Temperature, Voltage, Current and mAh consumed. This is accomplished by connecting the ESC telemetry wire to the flight controller with a spare UART.

ESC Telemetry currently supported are :

• BLHELI32: BLheli and KISS
• HOBBYWING V4: Platinum PRO V4, V4.1,& FLYFUN V5
• HOBBYWING V5: Platinum V5
• SCORPION: Unsc Telem
• KONTRONIK: Kosmik & Kolibri
• OMPHOBBY
• ZTW: Skyhawk
• APD: HV Pro UART telemetry
• FlyRotor:
• Graupner:
• YGE: OpenYGE - Note - The ESC must have firmware V1.03547 or above. At the moment this is in beta and has not been released. Please use the contact form to request the updated firmware. YGE: Contact Us

Select Serial Port

The ESC telemetry pin TX needs to be connected to a spare UART RX.

Select the UART from the Configuration page.

Select the Protocol

Select the correct ESC telemetry protocol based on the one you are using.

Power Config

Enable the Voltage and Current from the Power Tab.

For Hobbywing V4 Additional parameters are provided for the voltage and current gains, and zero offsets. These parameters are set to zero by default to enable the Auto-Calculation within the firmware.

• set esc_sensor_hw4_voltage_gain = 0
• set esc_sensor_hw4_current_gain = 0
• set esc_sensor_hw4_current_offset = 0

note

Only change these values if Auto-calculation is inaccurate and you wish to fine tune the voltage and current.
You can use the below values as a starting point.

Model	Voltage gain	Current gain	Current offset
Platinum LV 60A	109	0	0
Platinum LV 80A	109	146	409
Platinum LV 120A	109	110	377
Platinum HV 130A	210	157	0
Platinum HV 200A	210	157	477
FlyFun HV 160A	210	66	381
