Is there anyone who knows about the CH341T chip?
When I was learning about drawing boards, I designed a small learning board for STC5410AD. But later, the teacher wanted to make this board. When the manufacturer made it, a problem occurred during th
Please advise, how to connect the positive terminal of the voltage regulator tube?
Hello everyone, the output end of the transformer in the figure, after rectification by V5, the voltage is about 26VDC. Among them, E5 and G5 are the g and e ends of an IGBT BSM200GA120DN2C. V502 is a
