Airbot F4

Want a cheap F4 board with lots of potential? This Revolution clone in its "acro" form does offer F4 performance for ~$20. Unfortunately it does require quite a bit of trial and errors.

Available through My Airbot. Banggood and readytoflyquads do also sell a similar board.

Another wiring diagram can be found in https://quadmeup.com/flip32-f4-airbot-f4-pinout/ More informations in https://www.rcgroups.com/forums/showthread.php?2731917-Airbot-F4-Flip32-F4-Thread

If you need PPM, then remove R19 resistor and use "ReicvrPort" in the hardware configuration tab If you need SBUS, then remove r20 resistor and use "ReicvrPort" in the hardware configuration tab If you need spektrum satellite, on the hardware configuration tab change the port to "MainPort"

The board comes with betaflight, in order to upgrade it to dRonin, please follow the (Naze 32)[https://dronin.readme.io/docs/using-naze32] instructions. with the following differences:

• No boot-pads: there is a boot-button on the left of the satellite plug.
• The card is not likely to be recognized by windows. In order to enable the appropriate drivers, just connect the baord while pressing the boot-button, release the button once the leds are blinking and run Impulse RCDriver Fixer. this small utility will load the necessary windows driver.
• In cleanflight, the firmware to be used is ef_revolution.hex . It is located in dRonin Firmware subfolder

Please note:

• that only the acro-version is compatible with dRonin, the Omnibus version with OSD, baro and mag sensors is not compatible. For that sort of price and features a genuine seppuku is a better choice.
• With dRonin Artifice, one cannot to connect to the FC through USB, when the FC is powered by battery
• Avoid rotating the flight-controller. The usb plug should be at the back of the quad, unlike other boards that can be rotated so that the USB is facing the left side, this board is confused by such positioning.
