# Sixth Lichuang Electric Competition#Voice Assistant

* 1. Introduction to project functions

The expansion board of Qiyingtailun CI-BO3GS01S offline intelligent voice module uses a microphone and speaker. It can select functions including infrared reception, transmission, three-color RGB and so on through the jumper cap, and has serial port upgrade and other functions. Through this project, I mainly learned how to draw a schematic diagram, how to lay out and draw PCBs according to the schematic diagram, and also learned some basic circuit diagram principles, such as USB power supply module, CH340 communication module, etc., and benefited a lot.
