QC3.0 decoder discrete component version, through this decoder, the output voltage of the QC3.0 protocol charging head can be deceived and fine-tuned from 3.6-12V in 200mV steps. I have welded many first versions before and gave them away. People came up with some improvement plans, so the second version was modified and shared with everyone. Since the express delivery is now out of service, the second version of the drawings is not plated, but it is definitely usable. The actual photos can only be borrowed from the first version.
