[Verified]CH32V003F4P6 core board V1.1

The TYPE-C interface has been connected to TX and RX, but the normal new chip does not support serial port download. You need to use Qinheng’s official WCH_LinkE to download the
 
drawn package library CH32V003 core board_Wen Gong resources- Jialichuang EDA (lceda.cn)
 
can Use 3.3 or 5V power supply. You can choose freely through the jumper.
There is AMS1117 on the back.
If you solder AMS1117, it will be a 3.3v power supply. The VCC interface will
input 3.3V. If you do not solder AMS117, but short the 5|3 jumper, it will be a 5V power supply. The VCC interface can also input 5V. If the output is 5V
and neither is soldered, it will be powered by 3.3V (at this time, the USB port does not supply power but is connected to ground and RX and TX, that is, serial communication can still be carried out normally). The 5V pin is left floating
 
on the back and you can only short-circuit part of the jumper and not solder the components. In theory, it can be attached to the board, but it is best to use pin headers to connect
 
most components. It does not support buying one or two components. I bought 20 components without CH32V003 for a total of 59.66 yuan. The BOM of the attachment is 25.03 yuan for one copy.
