A guide to wiring up TBS Crossfire Micro Receiver V2 to the Omnibus F4 Pro.
Board Connections¶. GPS is attached to UART6 (SERIAL3) Telem is available at UART 1 (SERIAL1) The shared USART3/I2C pins are,by default, enabled only for I2C operation to allow external compass or digital airspeed sensor attachment.If at least one device attached externally, does not have pull-up resistors, then 2K ohm pull-up resistors will need to be added externally. The green-circled white wire is IRC Tramp telemetry wire (connected to softserial 1, ledstrip port). Help Omnibus F4 Pro v3 + 4s battery: david9981: 8: 790.

As you can see on the diagram, I'm planning to tap the ground line between the Cam and VTX, and route it to one of the AGND pads on the FC. The Airbot Omnibus F4 Pro V3 FC takes flight controller functionality to the next level.
The latest iteration in this reliable and capable series of flight controllers, the Omnibus boasts an onboard Betaflight OSD with current sensor and VBatt, 5v 3A BEC output, video output filter, and the ability to /5(11).Betaflight OMNIBUS F4 Pro /V2 Flight Control wiring ?Omnibus F4 AIO - Page 25 - RC Groups

Serial Port Planning
The Omnibus F4 Pro V2 offers 3 UARTs.- UART1 - Used for SBUS
- UART6 - Available
- UART3 / I2C - Available if I2C is not needed
- UART1 - Used for SBUS
- UART6 - GPS
- UART3 / I2C - Compass
- Softserial - Smartport
Smartport
There's the resistor, temporarily sitting on top of the processor. I circled the two pads it's going to be crossing below.
In order to use the Softserial port, it needs to be enabled in the iNav Configurator.
I enabled Softserial, and while I was at it, also enabled telemetry.
After a reboot, I went into the ports page, found the Softserial port, and configured it for Smartport at 57,600 bps, as suggested.
The final step was to go into the CLI and apply two settings:
set smartport_uart_unidir=OFF
set telemetry_inversion=on
Omnibus F4 Pro Soft Serial Killer
Having done that, I was able to go onto my transmitter, do a 'discover', and telemetry values populated from the flight controller.One additional note. The GPS telemetry does not appear for a 'discover' on the radio until you have a GPS lock. This caused me quite a bit of frustration. Once the telemetry is discovered, it will be on the list on the radio, thereafter. You do not have to rediscover it after it is in the list.
RSSI
The Omnibus F4 V2 uses a tiny little pad in the middle of the board to receive RSSI data from the receiver. Many people are soldering a small wire to the pad, and just hanging it off the Flight Controller, with a bunch of glue and hope holding it in place. I didn't really like that solution. Instead, I opted to hijack the RAM pins to make the RSSI externally available.
Omnibus F4 Pro Manual
The RAM pins on the Omnibus F4 pro V2 are wired together, but otherwise isolated, if you do not solder a jumper elsewhere on the board, linking them either to VCC or the 5v rail. Since I left the jumper undone, the RAM pins are just tied to each other. Since I'm powering my Camera and VTX via an external wiring harness, the RAM pins are unused.I soldered a small jumper from the RSSI pad to one of the RAM pins. I will then solder a heavier gauge wire into the other RAM pin hole, and connect that to the wiring harness going off to the receiver. This should provide greater strain relieve for the RSSI jumper. I think this is a much more resilient solution. Here's the jumper wire going to one of the RAM pins. This picture does not illustrate the wire harness leading off the board.
