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:
- The layout of the components and trace widths, especially for power lines.
- The management of LiPo battery charging and discharging to prevent any risk of overcharging or over-discharging.
- 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!
