Enable SoftSerial_TX on S5 or S6 pad
1. Connect the inverted telemetry signal to S5 pad
2. Turn on “SOFTSERIAL” & “TELEMETRY” in Configuration tab
3. CLI commands as following
- resource motor 5 none
- resource serial_tx 11 B03
- save
4. Choose SOFTSERIAL1 for Smartport in Ports tab.
Enable Camera control on RSSI pad
1. Connect “OSD” pin of camera to RSSI pad
2. CLI command as following
- resource camera_control A00
- save
3. Stick commands for controlling the camera
- DISARM
- ENTER: Roll Center, Pitch Center, Throttle Center, Yaw Right
- LEFT: Throttle Center, Yaw Left
- RIGHT: Throttle Center, Yaw Right
- UP: Throttle Center, Pitch Up
- DOWN: Throttle Center, Pitch Down
- Adjust Value: Pitch,Throttle & Yaw Center, Roll Left or Right
Tips
- Enclosed brass grommets are used to converte M3 to M2.
- Enclosed silicon grommets are necessary to avoid the vibration woes.
- T2 can be used for Smartaudio VTX & Tramp VTX protocol.
- T1 can’t work with Tramp VTX protocol
- Non-inversion hacks must be required for Frsky Smartport on T2.
- DSM2, DSMX, IBUS, SUMD signal can be connected to R1 or R2
- PPM share UART2-RX(R2) pad
- S5(PB3) & S6(PB10) can be resourced to Softserial for Smartport
- Rssi pad, PA0 with TIM5_CH1, can be resourced to Softserial or Camera Control
- No Blackbox
