#8th LCSC Electronics Design Contest# Electronic Clock

 
 
* 1. Project Functionality:

A desktop clock displaying time, date, etc., powered by an external battery, utilizing hardware-based solutions whenever possible.
 
* 2. Project Attributes:

A 2023 Summer Training Camp project. This project is not yet publicly available, has not won any awards, and is an original work.
 
* 3. Open Source License:

*4. The hardware

uses the original schematic, but the lithium battery charging chip has been changed. An onboard CH340 programmer has been added, allowing for direct programming via USB without a traditional programmer. The programmer uses a separate self-locking switch for easy firmware updates.
The PCB is a four-layer board, using my casing. The PCB thickness is 1.2mm. The battery size and
touch buttons use my custom 6x6mm touch buttons. If you don't have a suitable alternative, you'll need to modify the touch point openings.
Regarding the casing: the openings on the DHT11 are too small, causing the buttons to protrude after installation; the front button openings are too large and need to be adjusted to fit your desired button size.
 
*5.

Regarding the software, I'm not very familiar with it, so I used the software programming files provided in the training camp. Some circuit structures may not be needed. If you want to replicate this, you can modify the files provided in the training camp or sacrifice some hardware performance to directly program the device.
