So I have this interesting build I’m working on. A custom Eachine Cvatar. I’m trying to configure a FlightOne MillivoltOSD flight controller with a BLHeli32 35a Eachine esc.

I want to double check my harness, but I’m almost certain it is all correct. When I plug in a LiPo, it beeps like normal. However, for some reason when on the bench A) I noticed I don’t have any voltage reading in BetaFlight for my LiPo which is full, and B) when I go to the motors tab to test and or configure the motors, I try to simply spin them individually with the sliders, and I have no movement in the motor, not even a stutter at all.

Now here’s a bit of info:
I have I actually double checked the harness and the one not thing I did mistakenly was wire my motors in a backwards order, so I might need to remap my motors when and if I get this working. Anyway, as for the MillivoltOSD flight controller, I have the esc protocol bridged for BLHeli_S with Current Sensor. I did wire my receiver to UART6, and maybe I should have chose a different one? I’m running Crossfire, but notice the F1 fc I think is using uart6 for esc telemetry? Would that cause an issue?

TIA everyone!? I’ve been wrestling with this for over a week now! I was able to flash the fc with BetaFlight 4.3 and everything up until now seems to be working fine!?

Sorry but you are all over the place: "BLHeli32 35a Eachine esc" and then " I have the esc protocol bridged for BLHeli_S with Current Sensor".

"I did wire my receiver to UART6, and maybe I should have chose a different one? I’m running Crossfire, but notice the F1 fc I think is using uart6 for esc telemetry?"

If you have an ESC telemetry pin on your ESC then its probably a BLHeli_32 ESC and you can connect that to any available UART on the FC and set ESC telemetry on that UART in the Betaflight ports tab.

For the voltage readout, ensure the voltage readout in Betaflight is set to ADC or use the following cli command:
