Binding procedure:

  1. Supply power to the flight controller by plug USB, wait until the red LED on the FC is off, immediately turn off the power, and then repeat again the above steps. When the FC is powered on for the third time, the red LED light will start to double-flash, which means that the Receiver enters the binding mode
  2. Please make sure your ExpressLRS tx module firmware is v3.x.x. And go to ExpressLRS.lua from “TOOLS” menu of your radio transmitter. Then hit [Bind] to binding with the onboard ExpressLRS receiver. The red LED should blinking slowly first then turn to solid, that means binding was successfully. If the red led keep tri-flash after binding ,please change Model Match tab value from “off” to “on” or from “on” to “off”

Receiver LED status meanings:

Red LED solid means bind successful or RC link established; Red LED double-flash means get into bind mode; Red LED flash slowly means no RC signal input from TX module; Red LED continuous flash fast means ExpressLRS wifi enabled; Red LED tri-flash means model mismatch need to change model match from “off” to “on”.

UART description:

ELRS receiver was connected to UART2 default out of factory.
Usually UART1 was used for MSP OSD with HD VTX.
UART6 could be used for GPS or other serial equipment.
IRX6 is an inverted serial RX6 for SBUS input.
IRX6 and TX6/RX6 couldn’t be used at the same time.

NOTES:

If upgrade firmware to betaflight 4.4.x , need to add custom Defines “GYRO_SPI_ICM42688P ACC_SPI_ICM42688P” from build configuration of betaflight configurator otherwise gyro will not working . 

If you want to enable Barometer , please connect to betaflight configurator and go to CLI command ,then type the following command:

resource I2C_SCL 2 B10
resource I2C_SDA 2 B11
set baro_bustype = I2C
set baro_i2c_device = 2

Great fit for a 2005 Honda Element
These fit my 2005 Honda Element perfectly. Solved a small leak issue. I’ve had these installed for about one season so far (winter into summer) and they are still holding up. The install is simple if you’re confident working on your power steering system. Overall happy. No complaints
