[Original*] Color silkscreened STM32F407VET6 basic system version

Overview

Image source: Pixiv artist.

I have absolutely no experience with Photoshop. This is my
first open-source project, and I integrated it using Windows Paint. Please forgive
any shortcomings. The schematic was copied and slightly modified. It's
an STM32F407VET6 minimum system board (with USB serial port ). The

serial
port uses a CH340C
microcontroller with a built-in 1.5A self-resetting fuse for protection against sudden failure .
PE14 and PE15 are for programming control LEDs (ice blue) and a 5V LED (blue).

Please ensure the power supply voltage does not exceed 5V. I didn't consider the power supply issue when designing the CH340C serial port circuit.

I hope to provide more advice for beginners.
I don't have a hot plate or low-temperature soldering wire, so please don't ask me if my soldering is bad. This board floats as soon as I apply solder when connected to the network.

Multifunctional test pen

This multi-functional pen can be used to measure resistance and output PWM waveforms.

A portable multi-functional test pen with voltage measurement, continuity measurement, diode detection, and signal output functions was built based on the CW32F030.
This pen is a minor modification of the official design.
1. Main controller: CW32F030C8T6

; 2. Charging circuit:

This multi-functional pen uses a TP4056 power management chip to charge the battery (the official solution uses TP4057)
. Since there are many TP4056 power management chips available, the TP4057 was not used;
3. Power supply for the analog section;

4. Schematic diagram
