stm32f401 expansion board

Overview

The ws2815 light strip driver board
supports the host computer to control the special effect mode, speed, step, color, and
supports the mobile app to control the color.
It supports the voice control of Xiao Ai.
It supports the ws2815 light strip with 3-channel 12v power supply. The maximum
power supply for a single lamp bead is 350. Provide 12v4a or above, otherwise all white will cause abnormal output, but may make the board hot.
The espwifi module can be debugged by setting the jump cap. The onboard typec port communicates through the usb virtual serial port. The universal c port charging cable can be used.
The miniusb on the side uses the ch340usb driver. Both communications can be controlled.
Most of the io leads. It’s also great as a development board
