I soldered up an iSpindel using a Lolin D1 Mini V4. One of the steps for iSpindel assembly is removing a diode that results in 5V going to VCC (e.g., iSpindel Assembly - Open Source Distilling). However, I'd read online that V4 removed the diode from 5V to VBUS, and had assumed that diode was the same one as was removed in V3. Weeeeeeell, after charging it after use in a beer, the Mini won't fire up, so it appears my assumption was incorrect.
Going to replace the D1 mini, but want to make sure I remove the diode properly this time. Attached is a photo of the V4 board. Is the part in red the proper one to remove? I know next to nothing about electronics, so reading the circuit diagram didn't help a whole lot.
