Hi @electroAJ, thanks for the detailed writeup and follow-up SKU info.
From a hardware standpoint, the 200mV droop you are observing on VDC_5V_LOCAL and VDC_5V_LOCAL_USB1 during ToF activity is not a concern at the rail level. That kind of transient is most likely localized contact/pin loss at the connector interface rather than a bulk supply issue. On a 5V rail, 200mV is well within normal operating margin. The eFuse on that rail does not assert until approximately 4.4V, so a 200mV droop from 5V puts you nowhere near that threshold. Downstream logic is regulated from a 3.8V VBAT rail that has demonstrated margin well above the minimum needed, and that rail is permitted to droop past 3.3V before any real issue occurs. The ToF-induced droop is not your RC dropout culprit.
Additionally, the M0129 VOXL Mini ESC power stage has been proven to the same load capability and test rigor as our standalone M0041 power module, using the same parts, so the supply itself is not a suspect to me. Would hate to see you chase a red herring.
The I2C errors and UART dropout sequencing are worth looking at together as they may share a common upstream cause. Beyond that, this one is likely better handled by our software team who can dig into the dmesg and service state in more detail. I will flag this thread for them.
