Feature:
- Plug and play ecosystem: dedicated ports for VTX GPS camera RGB LED and buzzer reduce solder points to as few as 14 for faster cleaner builds and fewer wiring errors.

- Built in ELRS 2.4G receiver: no separate RX needed preinstalled antenna port saves space speeds assembly and delivers low latency long range control.

- Direct RGB LED support: onboard 5V 4A BEC powers LED strips without extra BEC switch lighting from radio or SpeedyBee App for standout builds.

- Bluetooth tuning anywhere: wirelessly adjust Betaflight parameters flash firmware and set LED effects from your phone no laptop needed.

- 32 bit OX32 ESC firmware: smoother throttle response cleaner transitions and precise control versus traditional 8 bit ESCs.

- 45A class AIO power stage: 8 layer 2oz copper PCB improved thermal headroom dual negative battery pads and optimized solder pads for cleaner routing and easier joints.
