Provides brake signal or enables cruise control in E-surf mode.
Selects speed signal source from Motor Wire, Hall Sensor, or VESC for RPM/Speed display.
Distance calculation is only supported in Esk8 mode for electric skateboards.
Distance is accumulated speed x time based on Motor Wire or Hall Sensor input.
Distance is calculated from VESC ABS data via UART port when VESC is selected as speed source.
Main battery voltage display functions in both Esk8 and Esurf modes.
Voltage obtained from VESC via UART or BAT port on receiver PCB.
Ensures correct main battery voltage display by maintaining common ground between receiver and battery.
Remote displays voltage in bars based on type/number, flashing when low.
Displays voltage, current, and temperature from VESC via UART port after proper connection.
Motor temperature measured via a built-in 10K NTC thermistor connected to the hall sensor connector.
VESC_TOOL requires setting the Beta Value for Motor Thermistor to 3950K.
Covers states, operation, current limits (3A), and usage recommendations for the relay switch.
Details transistor switch operation, voltage limits (5-12V), wiring cautions, and LED control.
VESC identifies remote throttle settings and offers two modes: Current and Duty Cycle.
Motor current is control target; free slide upon release, recommended for skateboards/surfboards.
Motor RPM is control target; instant stop upon release, suitable for differential control.
Details signal strength, battery voltage, control mode, throttle percentage, and switch status.
Shows motor RPM in ESurf mode, with display text varying based on speed source selection.
Explains navigation to speed/distance, unit settings, and speed source variations in Esk8 mode.
Esurf mode only displays motor RPM, not speed or distance.
Displays min/max voltage/current from VESC via UART, requiring VESC as speed source.
Displays VESC and motor temperature from VESC via UART, requiring VESC as speed source.
Enter main menu by holding the brake trigger to the end and pressing the function button.
Exit sub-menus to main menu, and main menu to interface, using brake trigger and function button.
