Hello,
Can anyone help identify the component circled in the picture?
I have two new Heltec V3.2 boards that have burned out this component. They were both fine on USB power flashing the Meshtastic firmware. I connected a battery with the board outside of the case, which worked both to power the unit and charge the battery. However, when I tried to install the unit into one of the MuziWorks H1 style cases that I had printed, it overheated and burned out the circled component when I tried to snap on the back. I thought that I was compressing things too much (the antenna and battery wires are too long), so I printed the ‘large’ version of the case which should have had more room for the extra wires. Unfortunately, the same thing happened to the second board even with the larger case back.
No other components appear heat damaged and the boards power up and function with USB power so I assume that it is something in the LiPo charging / power circuit, but the component is burned/cracked badly enough that I can’t read the markings.
I’m hoping to identify the issue so I can avoid repeating the problem with any future Heltec boards.
