BateInquiry about battery for 7-inch HMI
Can you tell me which battery is suitable for a 7-inch Elecrow HMI Display with an integrated ESP32-S3? Once connected, does the battery charge through the USB port?

Hello,
A 3.7-4.2V lithium battery
Hi @luisalvarezi
Yes the battery will charge through the USB port from my testing and what I can tell from the schematics. It looks like the battery charger is a 4054A from Linear Technology set to charging at a max of 500mA.

I was wondering the same thing for one of my projects.
