General question here - I have a National Instruments DAQ setup to measure the current draw from the LiPo battery on an Electron. I’ve set it up this way because I don’t have a current scope probe. I am able to see a time-based graph of the current draw and am curious on where these 90 mA current spikes are coming from while in SLEEP_NETWORK_STANDBY mode. They occur every 110 ms.
Is is the STM32F205 micro, U-Blox cellular module, BQ24195, regulator, MAX17043 fuel gauge?
If you average the y-values in this time graph out, you get an approximate constant DC current: 10 mA
Obviously, this measurement method is not the best because of the resolution, but still curious on what circuit these spikes come from.
