      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:

      Great for dogs like to to chew and like squeakers!
      Color: Mixed, Size: Medium, Color: Mixed, Size: Medium
      Harder to hold up to his bites. He started to pounce on it to make it squeak like he was honking the horn. He likes it and carries it around the house. Its a must buy for medium to large dogs

      Dog & I Disagree/ Aggressive Chewers Short-Term Toy
      Color: Red, Size: Medium
      This is day two, and, My dog LOVED this toy! He loved the squeaking aspect, chewing the center squeaky area so he could squeak it himself (adorable!). He also loved playing fetch with it, but he loves fetch, but this was fun for him as it wasn't a ball. The chewing enjoyment is where it was at for him as he Loves to chew, and it was a nice weight that he could really carry around and have fun. I did love this toy, as it was cute, and he was having such a great time with it! Until his teeth kept getting stuck in the rubber around the center squeaker area when getting it to squeak by himself. That was almost it, but he LOVES this toy, so I gave it another chance. Then, one of his teeth got stuck in the center and his teeth became hooked on the top of the outer round and he couldn't get it out of his mouth. That was the End. Perhaps more size options, small, medium, and large, with safer spaces, at each size, between the squeaker area and the outer ring- so they can squeak it, yet avoid getting their teeth stuck and/or their mouths stuck open. I would say the durability is lacking, as, while similar, a Benebone it is not, though it gets sharp too-ouch! He had the outer rounds pretty tore up on the first day, and even more tore up today, so if you have a truly aggressive chewer, this is also a short term toy. This is a fun toy and many love it, though many more could love it with a few modifications. As it is, I did not find it a value for my money, even with as much fun as he had; at this time, the safety aspect and the ease with which he chewed it requires I look somewhere else. I hope this helps.

      Great for aggressive chewers
      Color: Mixed, Size: Medium
      This toy held up well. My dog is a very aggressive chewer and will shred apart any toy she can. She was not able to tear up this one. I have not found many toys that she doesn't destroy
