kason walnut shake toy PCB control board

Overview

I recently saw that my favorite up owner Kason open sourced a walnut rocking toy, and I really liked it, so I drew a pcb control board of the walnut rocking. There are LED lights under the board, which can be used as ambient lights, and there are designed PCB translucent lights on the side. The strips increase the beauty. This board uses commonly used lithium batteries for linear charging, and also takes advantage of the characteristics of mos tubes to adjust the motor's speed steplessly. The board also leaves space for installing a Bluetooth module, which can be installed with the HM-M38 Bluetooth module. Toys add music functionality.
