The stand is divided into a front panel and a back panel. There is a TTP223 touch control circuit on the back panel, which is connected to the front panel through copper pillars to achieve electrical connection while allowing the stand to stand. Just touch the "Demon Slayer" logo under the front panel to switch it on and off. The backplane includes a USB interface, a 20-50pf, a 0805 capacitor, a ttp223 chip, and a pnp chip transistor.
