      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.

      Love the look but runs narrow
      Size: 7 Toddler, Color: Navy, Size: 7 Toddler, Color: Navy
      Obsessed with the navy, it literally goes with everything. Quality is great too, really happy with how they’re made. Super cute too. Only thing is my son has wide feet and they ran a little tight on him. If your toddler is on the wider side, might be worth sizing up. Overall still happy with them!

      Snug fit with ease of putting on
      Size: 7 Toddler, Color: Navy, Size: 7 Toddler, Color: Navy
      These Amazon Essentials hook-and-loop athletic sneakers have been a fantastic everyday shoe for toddlers and little kids. The fit and comfort really stand out. The padded collar and cushioned insole make them comfortable enough for all-day wear, whether that’s running around at school, playing at the park, or just being on the move at home. One of the biggest wins is how easy they are for kids to put on themselves. The hook-and-loop closure combined with the faux elastic laces strikes a great balance between a secure fit and independence, which is a huge plus for busy mornings. They stay snug without being tight and don’t slip off during active play. The materials feel well made for a kid’s sneaker. The faux leather and mesh upper looks sporty and holds up well to daily wear, while the mesh lining helps with breathability. The TPR sole provides good traction and stability, giving a solid, supportive feel without being stiff or heavy. Style-wise, these shoes are versatile and cute. The athletic look with subtle vintage-inspired details works with everything from play clothes to more put-together casual outfits. Overall, these sneakers deliver comfort, durability, and kid-friendly design at a great value. A reliable, no-fuss choice for active little feet.

      Slim toes and runs small.
      Size: 11 Little Kid, Color: Metallic Gold
      These sneakers ran small and are very slim down the foot. Definintely not wide friendly or even toe box friendly for those who want more friendly 'barefoot' shoes. The colors are cute. Easy to put on and off, especially for toddlers with the lack of laces. Just not a great sneaker for those who want something that will last longer and not pinch toes or create ingrowns.
