Hello everyone, I have an issue with my power supply/ battery management. As you can see in the schematics I attached, I have an SDS011 connected to an ESP32 and is taking power from a step up converter that has at his heart a ME2108 that can hold max 600mA load. Thing is that ESP32 has huge spikes in current draw when I activate WIFI. This issue is non existent if I disconnect the SDS011. So by activating WIFI + SDS011 the voltage drops in like 2-5 seconds from 5V to 0.60V. I did some debug
