I’m building an rc plane using some solar panels and a 4s mppt charge controller.
Yesterday i connected my Mppt charge controller to the pm07 board and then connected the 4s battery. In order to know how much power the solar cells produce, a current and voltage sensor is used between the battery and the mppt. However, upon connecting, this resulted in a current spike and the output of the current sensor rose so high, the input caps of the px4 smoked up.
I used the usb cable to check if everything is still working and it’s fine. Now I’m just wondering what i should put in place of the old caps. Here’s a pic of the current state of the board
