MultiNav Pro+ Power Kit - super-cap voltage sag under heavy BLE TX load?

Douglas YoungJune 12, 2026
Been running the Power/Program Kit with the BLE module and I'm noticing something weird when the BLE module fires up a long-range transmission burst. Voltage on the rail dips pretty noticeably - like enough that I can see it on my scope - and I'm wondering if the super-capacitance system is actually sized to handle the peak current draw of the RF front-end at full power, or if I need to add some external bulk capacitance myself. The BLE module's RF front-end is no joke when it's pushing for long-range, so I'd imagine the instantaneous current spikes are pretty significant.
