OMNIBUS F4 Nano V5
Pinmap
The Omnibus F4 NANO V5 flight controller using MPU 6000 gyro and
STM32 F405 MCU, with upgraded BEC design, it works up to 6S. other
important features include BetaFlight conigurable OSD, barometer.
The redesigned 4in1 port supports ESC telemetry function now, there
is one jumper for setup the current source, for example, ADC or ESC
telemetry.
Firmware update
OMNIBUS has been supported by Betaflight v3.2, you can use Target "OMNIBUSF4SD" to update the irmware.
How to use the onboard USB port updated irmware in GUI on windows
To Flash the Firmware you have to enter the so called DFU mode. On Windows 10 I had to use a tool called Zadig (download and start it) to be able to switch
drivers for DFU mode to work. In order to switch drivers you have to take the following steps.

• Push BOOT button on the Flight controller.
• Plug-in the USB cable (the red LED should not be as bright as normally).
• Fire up Zadig and hit “Options” and then “List All Devices”.
• From the list choose “STM32 BOOTLOADER”.
• Under “Driver” choose “WinUSB” on the right and hit “Reinstall Driver”.
• Close Zadig, disconnect the Flight controller, close all Google Chrome instances.

Jumpers
Resources:
The Omnibus F4 NANO V5 includes a current source selection jumper (see below for setup details):
If you are using 4in1 ESC board, like ORI32 and it is connected using the 8 pin Sh1.0 Socket, you need to choose between RX3 (to receive ESC telemetry) or
CRNT (ESC current meter sensor) by jumping J2 middle pin (RX3/CRNT) with upper pin (RX3) or lower pin (CRNT) as indicated in red in the image below.
