Based on this circuit or related peripheral drivers, various applications can be extended.
3 Hardware specifications
Processor: ESP32C3 (WiFi, Bluetooth)
Screen: 0.96 TFT color display
Operation: Multi-directional reset button
Power supply: Charging and discharging includes lighting (flashlight), soft power on/off
Circuit: buzzer, voltage sampling
4 Instructions for Use
Burn the program, use it immediately upon power on, set it to save when powered off, and automatically load the last settings.
When the main control chip is QFN packaged and soldered, please use a heating table → DC low-voltage heating table
Pay attention to distinguishing components with positive and negative poles to avoid short circuits.
Before powering on, please do not necessarily check for a short circuit to avoid chip burnout!!!
