Color silkscreen PCB heated mouse pad

       This self-designed heated mousepad uses a PCB-based heating unit and JLCPCB's color silkscreen printing technology. Powered by a mobile phone charger, it's both aesthetically pleasing and practical. The heating pad designed for this project has a power output of approximately 6W. I embedded it in a solid wood board, flush with the board surface. A Type-C female connector is then installed on the side for power with a 2A or higher charger. Alternatively, you can place it under a regular mousepad, with the power supply either led out via a wire or soldered directly onto the board. This mousepad, made with solid wood and a PCB, is much more environmentally friendly than those artificial leather heated mousepads sold online, making it especially suitable for long-term indoor use.
       Placing a regular mousepad on top of the PCB provides a better feel and better heat retention, with the surface temperature remaining around 35-40 degrees Celsius, which is very comfortable. To prevent the risk of overheating from prolonged power-on, it's best to fix a normally closed 55-degree temperature control switch on the back of the PCB using silicone. The product model from JLCPCB's online store is provided in the schematic diagram for reference.
