Description:
Features
- Betaflight serial passthrough. It is convenient for pilots to flash any version of ELRS RX firmware and especially can flash ExpressLRS V3.0 without updating flight controller firmware.
- The SPI Frsky version board reserves an SBUS port and a UART port, which is available for the SBUS protocol receiver or other external receivers.
- Built-in an 8MB flash memory chip dedicated to Blackbox logging. It's an extremely powerful tool for tuning and troubleshooting an FPV drone.
- Integrated motor pin connectors, it is easy to install motors without soldering work.
- Particular design with only 3.6g ultralight weight, reasonable layout, and easy to build. With a 26*26mm mounting hole size, it is fully compatible with the whoop frame in the current market.
