Request for Recommendations on ESP32-C3-MINI-1-N4 Schematic and PCB with LiPo Ch

(1/1)

Hello everyone,

I’m working on a project  using an ESP32-C3-MINI-1-N4 module. Here is the first version of my schematic and PCB for this project. The design includes:
- An ESP32-C3-MINI-1-N4 for WiFi/Bluetooth connectivity,
- A charging circuit based on the TP4056 for a LiPo battery,
- A 5V to 3.3V power conversion using an MIC5205-3.3 regulator to power the ESP32.

I would appreciate your feedback and recommendations on the following points:
1. The layout of the components and trace widths, especially for power lines.
2. The management of LiPo battery charging and discharging to prevent any risk of overcharging or over-discharging.
3. Any suggestions to improve the efficiency and stability of WiFi/Bluetooth connectivity, considering the use of the onboard antenna.

Thanks in advance for your insights and advice!
