- Do not file the mounting holes as this may cause damage
Recommended steps for installation of the FETtec AIO 35A
- Connect to FETtec Configurator and update to the latest firmware (see firmware update and settings)
- Install the AIO in your copter (see Connection diagrams for correct wiring and installation)
- Make sure everything is connected properly and check without propellers
- Connect to KISS GUI to proceed with final configuration of the FETtec AIO 35A (FC configuration)
Connection Diagram
Connection Layout top
Receiver connector:
- GND
- 5V
- TLM: Telemetry signal to receiver
- SIG.: Receiver signal to FC
Acronym explanation:
- Motor 1 – 4: pads for motor connection
- GND: Reference Signal Ground
- 3-6S – / +: Battery input voltage (12V-27V)
- Reset: Reset button to force the FC in bootloader mode, not needed for normal operation
- RGB_LED: pad for LED connection
- 5V/GND/RX4/TX4: If onboard OSD is deactivated these pads are the connection for another free serial (e.g. GPS)
Connection Layout bottom
The 8 pin connector combines all necessary connections for analog or digital VTX and camera. It includes:
- VCC (Lipo+)
- GND for cam and VTX
- Video in: Analog video signal from cam
- Video out: Analog video to VTX
- BEC 5V/16V: power supply for cam and/or VTX, switchable voltage, real Pit capable
- VCS/TX3: for smart audio / tramp configuration or TX for digital FPV systems
- RX3: for digital FPV systems
4 pin connector:
- GND
- 5V
- TX1: function configurable in GUI
- RX1: function configurable in GUI
Onboard OSD Jumper: bridge to deactivate onboard OSD and to activate RX4 and TX4
Firmware update and settings
The FETtec AIO 35A works with KISS/FETtec FC firmware version 1.3RC47i or
later ! The FC, ESC and OSD of the FETtec AIO 35A Board are flashable over
the FETtec Configurator. Download the FETtec Configurator here:
https://github.com/FETtec/Firmware/releases
FC Firmware update
- choose USB and select the correct COM Port and press connect.
- You should see the FETtec FC G4 as shown.
- Click “Remote Firmware” button and select the latest available firmware.
- Press “Flash selected!”
- FC is flashed now!
- Settings can be made in the KISS GUI.
- Download:
Reconnect USB after this step!
We recommend to always use the latest available firmware to get the best user
experience If you like to try new features and firmware developments you can
join our Discord channel and download the latest beta firmware to try on your
own risk (https://discord.gg/pfHAbahzRp)
ESC Firmware update
- Choose KISS FC Passthrough and press connect.
- all devices should show up now. The Overview page allows to flash individual ESCs.
- The Setting page allows to adjust all available ESC parameter.
- Reverse rotation direction
- Slow start
- 3D mode
- PWM min & max signal
- ESC Beep enabled
- Current calibration
- Individual ESC ID (for use on onewire protocol)
- In the Telemetry page you can spin th motors, view and debug the motor telemetry.
OSD Firmware update
To update the OSD connect to FETtec Configurator and flash via FC passthrough
latest firmware.
OSD Settings
All settings are to set directly in the OSD To get in the menu move the sticks
in the shown direction at the start: Throttle 50%, then move Yaw left, Pitch
up
OSD menu:
OSD settings:
Issues with the OSD
- OSD SYNC → AUTO SYNC
- in case of blurry lines play with LEFT/WITH values try to avoid WITH values above 400
- make a PAL/NTSC layout reset
Move elements in the OSD menu
Choose LAYOUT → SET POSITIONS in SETTINGS. Now the elements are movable along the grid. Skip between the elements and select them to set new positions. To exit the ´move menu´ hold stick Yaw left for a few seconds
