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

Really good pillow!
Size: King (Pack of 1)
This is the first pillow that I have owned in the last 10 years in which I have not experienced any neck pain. It's the right density, comfort level, and is a high-quality item. I am a side and stomach sleeper. Try this pillow and I think you'll be happy.

Excellent pillow, firm but more flexible than others of its type
Size: Queen Size: 27.6"L x 15.7"W soft, Color: White
I previously bought a similar pair of pillows from Sleep Innovations, but they are now either out of stock or unavailable. This new brand is a bit softer and more comfortable than the original pair. It's good for sleeping on my side or my back. The pillow cradles and supports the head and neck in a more contoured way than some harder pillows. The price is reasonable. The only difference from Sleep Innovations is that this pillow does not have a zip cover. So there is no way to wash the exterior. I suppose that one could buy a zip cover for it at extra cost.

Side sleepers rejoice!
Size: Queen Size: 27.6"L x 15.7"W soft, Color: White
I have spent hundreds of dollars on pillows. I am primarily a side sleeper and every few years I find myself waking up with a "crick" in my neck accompanied by pain and tension. I have had this pillow for only two nights and I am leaving a positive review. It is firmer than one would expect based on first appearance and the "press" test. The surface stays cool and I can sleep any which way and I am still comfortable. Definitely recommend!

Too Soft for Him, Just Right for Me
Size: Queen Size: 27.6"L x 15.7"W soft, Color: White
My husband purchased this for himself but found it to be too soft for his preference. I decided to try it, and it worked well for me. While I agree it’s not as firm as either of us typically like, it still provided adequate support, and the shape retention held up nicely. Overall, it wasn’t a match for him, but it worked just fine for my needs.

Great for a side sleeper. Firm enough that it doesn’t collapse but soft and cool
