IoT clock based on Essence ESP32-C3-12F module

Project Description

IoT clock based on Essence ESP32-C3-12F module

Project function introduction

1. Developed using Essence ESP32-C3-12F. 2. Use micro-usb 5V power supply and AMS1117 voltage stabilization. 3. As a digital tube driver, MAX7219 uses a 4-bit common cathode digital tube. 4. Function: Press and hold the back button to enter the download mode, RST is the reset button, press and hold KEY1 for two seconds to enter the time modification page, press and hold for 5 seconds to enter the automatic calibration mode, press and hold for 10 seconds to enter the Anxin WeChat networking mode, and modify the time mode, press KEY1 to adjust the modification position; press KEY2 in the time modification mode to decrease the time, and press KEY3 in the time modification mode to increase the time.

Precautions

1. The LED package is LED-TH BD3.0 "color". The actual welding uses 0805 packaged LED lamp beads, which is not a big problem. 2. In order to make the front appearance beautiful during design, the positions of the crystal oscillator and the buttons are overlapped. Pay attention to the welding. 3. Micro-USB is really difficult to solder, and there are no suitable tools. Even if it is finally successful, there will still be some minor problems with the clock due to contact problems. 4.
