CH32V003-Board
This is a small CH32V003-Board for any use.
When you have a project where you need a really cheap MCU there aren't that many options or not many options that are perfect.
The CH32V003 costs in bulk only 10ct. This is really cheap. It not only has a 48mhz core but also many features like I2C, UART...
To built it you'll need:
-the PCB
-a CH32V003(QFN-20)
-male Pin Headers
-0805 100nf capacitor
These only when you want to add a reset Button:
-0805 10k Ohm resistor
-3*4*2 2P SMD button
For programming you'll need a WCH-LinkE (not the WCH-Link or a clone) and 3 jumper cables. Connect the second pin to SWDIO, the third to 3.3V and the last to GND (the first pin is reset (not necessary)).
You can programm it with Arduino IDE: https://youtu.be/9tLTioG5xQE?si=rrI4-0cSZLzKuIEm
