1. receiver protocol Serial ELRS 2.4G RX uses the Crossfire serial protocol (CRSF protocol) to communicate between the receiver and the flight controller board. So the Serial ELRS 2.4G RX is available to support upgrading to ELRS Configurator with no need to flash Betaflight flight controller firmware.
2. Binding steps
● To enter the binding mode, unplug and plug the power/data cable three times;
● The RX LED will flash rapidly twice, indicating the receiver is in binding mode;
● Ensure the TX module or wireless transmitter enters binding mode;
● If the receiver's light stays on constantly, it means it's bound.
3. Upgrade steps
● The Serial ELRS 2.4G RX can be updated via Wi-Fi or Betaflight serial passthrough. Here is the way to update the Serial ELRS 2.4G RX firmware through passthrough.
● Insert the FC into the computer, but do not connect to the Betaflight configurator.
● Select the target "FLYWOO 2.4Ghz EL24P"
● Use the BetaflightPassthrough option in the ExpressLRS configurator for the upgrade
9V Electronic Switch:
By controlling the switch of USER2, it is possible to control all 9V power supply to the flight controller, temporarily shutting off the image transmission to avoid damage to the equipment due to prolonged high temperatures.
Connect the flight controller to the BF configurator and switch to the Modes interface.
Scroll down to find USER2, select "Add Range", then move the joystick switch on the remote controller you wish to configure. Afterward, save the motor settings. Activate USER2.

Setup was smoother than my older FC. Works great out of the box and binding with ELRS took only a few minutes. Good experience overall with Mepsking.

Really clean AIO board and the solder pads are actually easier to work with than I expected. Packaging was neat and everything arrived safely. Looks premium in hand.

I used this for a 2S HD whoop build, and it handles O3 without any issues. That 9V output really helps, no random power drops so far.

I’m still pretty new to building drones but this board was more beginner friendly than expected. Mepsking support helped me confirm the wiring before ordering. Really appreciated that.
