      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 or UART6 Could be 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
      save

      Great shelves!
      Size: 24x5.8, Color: Black, Size: 24x5.8, Color: Black
      I love these shelves (I purchased 6 shelves total). The size I got was perfect, looks phenomenal, & quality is great too! Only negative thing I’d say is that it could be difficult for some people to set up as it needs to be leveled, & can be hard to align with other things since the part that attaches to the wall is separate from the shelf (due to its floating design) but once it’s up, it looks great. Definitely good value for money with its quality. I have them to hold up decorations/toys, & you think some of my shelves have about 5lbs of stuff on it & I’ve had no issues, so functionality is good.

      Very nice. I am extremely happy with them. I used painters tape to hold the bracket in place while I screwed it in, worked like a charm 😁 holds a lot of items

      Good enough
      Size: 15x6.8, Color: Black
      As cheap as the day is long but functional. These are basically made out of highly compressed paper and finished to feel like wood. The first one I put up was good with a little tilt to the back which is fine. The second one has a more severe tilt and I had to bend the bracket down to decently level it out. They are sturdy enough to hold quite a bit of weight and look good for what they are. I'm not impressed but I'm also not disappointed, the price is a bit steep for what they are but they serve their purpose.

      Great, but bring your own inserts.
      Size: 24x7.9, Color: Black
      These work great, easy to install. Happy with them. Only problem was the instructions say don’t use the include inserts on wallboard, which meant I had to go out and purchase my own. That’s OK, because I like to use inserts I trust.
