Tips
- CLI “defaults” after reflashing
- Rubber anti-vibration standoffs are necessary to avoid the vibration woes.
- Put a piece of sponge on the barometer to reduce the impact of airflow.
- If you are using 5V VTX or HD camera, Pls power the VTX/HD camera via the 5V pad on FCHUB. The ribbon cable can’t bear heavy current.
- SBUS, DSM, IBUS, SUMD can be connected to any unused UART_RX.
- PPM share RX2 pad
- Frsky SmartPort, Tramp & smartaudio protocol can be connected to any unused UART_TX
- S6 pad (PA8) can be resourced to Camera Control
- pwm pad (PB8) can be resourced to Camera Control, LED_STRIP, or Motor
- SD Card, FAT32 C10, 1~32G, But max.4G space can be used in Blackbox.
