Open FETtec Toolset https://gui.fettec.net and choose ALPHA Configurator. 2. Connect the FETtec FC via USB. 3. Open the ALPHA Configurator and select open port. Choose the serial port on which the FC shows up and press connect. 4. If you have KISS FC firmware running on your FC, you will get a warning if you want to flash FETtec Alpha FC firmware. Press "OK" Select serial port again Page 14 5. "Select new firmware to flash". We always recommend flashing the latest available firmware. 6. Confirm to flash FETtec ALPHA firmware by pressing "OK" Page 15 7. FC firmware update is done! The FC needs a restart after that, therefore the com port is requested to be selected and connected again Now you can customize everything in the GUI according to your wishes. Please connect everything like described in the manual of the FC. The receiver signal will get auto detected (supported systems are Frsky Sbus+S-Port, CRSFv2 and CRSFv3 and Ghost). Page 16 Get back to KISS If the FETtec Alpha FC firmware is flashed on your FC and you want to get back to KISS firmware, follow these steps: 1. Open FETtec Toolset https://gui.fettec.net/ 2. Connect the FETtec FC via USB. 3. Press the reset button once 4. Open the FETtec ESC Configurator and select "USB" and connect. 5. Choose the serial port on which the FC shows up and press connect. 6. Now the FC shows up and you can select KISS Firmware (FETtec FC G4 1.3-RC47m) in "Remote Firmware" and press "Flash selected!" Page 17 7. Flashing to KISS FC firmware done. Page 18 Firmware updates For firmware updates it is the same procedure as flashing the FETtec Alpha FC firmware. Connect FC via open port and choose "Firmware". Now you can flash the latest firmware update via "Select new firmware to flash" or choose "Flash local file". We always recommend to 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 to be always up to date (https://discord.gg/pfHAbahzRp). Page 19 Settings You can set up the FC according to your wishes in the ALPHA Configurator. . All functions are explained in the respective category. For more information and help use the FETtec Alpha FC firmware manual available at www.fettec.net/download Page 20 Display connection I2C O-LED to FETtec FC G4-N v1.7 I2C O-LED display can be used to show the OSD menu and telemetry in order to be able to set up settings without computer or FPV goggles (FPV OSD). The I2C connection will block serial 3 which is mostly used for digital OSD or analog VTX control (VCS). The O-LED must be connected on power up to initialize but can be unplugged after set up is done. Supported display types: Required resolution 128 x 64px We recommend the 1,3" (SSH1106) version as the text size will be very small on the 0,96" (SSD1306) display.
