RP2040 Zero has to be powered with 5v or less. For higher voltage, a voltage regulator is needed.

It can be powered from the telemetry port or from BEC. Some receivers deliver 5v or less at the telemetry port, even if BEC voltage is higher than 5v. Check that voltage supplied to RP2040 is not higer than 5v.
