ESP32S3 Schematic Design

0:12

General (prev)
I will add a TP4056-based LiPo charging module (with onboard protection) and an AP2112 3.3V LDO to the schematic. Reason: the TP4056 module provides USB-powered charging plus battery protection in a compact module ideal for the 45×12mm form factor; the AP2112 is a small, low-dropout 3.3V regulator (SOT-23/SOT-25 family) that gives better headroom and lower quiescent current than AMS1117 for battery operation. I will add them as U8 (TP4056 module) and U9 (AP2112 3.3V LDO).
