Hello, I really like your challenge and I believe I've expertise to help you. Your software has been submitted.
1x GND 3V3 (P2 with 2 pins two.54mm) connector can be used to electrical power externally the WCH CH569 MCU (it is usually recommended to get rid of the P4/SHUNT in that scenario It is far from necessary as being the 3V3 LDO IC1 is protected towards reverse latest)
This characteristic can be a Beta Variation and will be rewritten employing very low level mode SDM TX/DM1 RX in an effort to be tricky genuine-time & ISO compliant, that can also deal with the emulation when using a Mobile phone...
By isolating the USB link, you defend your Computer system from opportunity voltage spikes, ground loops, or noise generated through the linked components.
