TLDR: Is a 5V/6A rail (ex: Power Module v3) able to power both the Flight Core V2 and VOXL2 without manual control dropouts? Or is there a specific setup required for this configuration to run reliably?
We are attempting to fly with the Flight Core V2 as the flight controller and VOXL2 as the companion computer. We are consistently experiencing manual control loss when connecting to and arming the craft. According to the logs, there are significant periods (hundreds of ms) where manual control drops out.
Our first setup was to power the Flight Core V2 via USB from the Microhard Modem Add-On's USB port. The Microhard Add-On is in turn mounted and powered by the VOXL2 which is in turn powered by the Power Module v3. Our theory was that the Flight Core V2 was struggling to be powered via USB, so we changed to a second setup: VOXL2 and Flight Core V2 powered by the same 5V/6A rail from a custom power board that has a very similar 5V rail to the Power Module v3. We still saw the manual control lost issue.
Notably, we are already suspicious of the Power Module v3 and its capabilities. We had a pre-flight check issue that claimed "Avionics power low" that was fixed by swapping out the Power Module v3 for another, suggesting that their power capability may be marginal for this use case or perhaps inconsistent for some other reason.
Alternatively, if there are other suggestions as to why we are losing manual control, please feel free to comment on that as well.
