CH32V003F4U6 development board

Overview

I have nothing to do recently, so I designed a CH32V003F4U6 development board with the "as narrow as possible" width requirement.
After soldering, this board can also be directly plugged into a breadboard. It has a CH340N USB to serial port, reset circuit, and WS2812 on board, which has been verified to meet the minimum system requirements.
Note: MCU uses 5V power supply, and IO is also 5V level.
WS2812 can select the connected pin (PD2/PC6) through a resistor, which can be controlled in PWM mode through its respective connected timer.

The finished product picture is as follows, and the test firmware obtained by splicing ADC_DMA (official routine) and ws2812 (self-written) is attached.
After the test firmware is powered on, the original value of each ADC channel should be reported on the serial port at a baud rate of 115200 for one round, and then ws2812 starts to flash in 8 colors (including one off/black/colorless) cycle.

Ask: Who knows the inner workings of a singing Christmas card? Thanks
I took apart the singing Christmas card and found that the components inside were very small. I was very curious and found that there was something that looked like a speaker connected to the circuit
