An USB isolator allows eradicate floor loops and minimizes electromagnetic interference (EMI) concerning the computer plus the connected system.
1x GND 3V3 (P2 with two pins two.54mm) connector can be utilized to electric power externally the WCH CH569 MCU (it is recommended to get rid of the P4/SHUNT in that scenario it is not necessary as being the 3V3 LDO IC1 is protected in opposition to reverse latest)
This function is actually a Beta Model and may be rewritten utilizing lower amount mode SDM TX/DM1 RX as a way to be challenging actual-time & ISO compliant, which will also resolve the emulation when employing a Cellular phone...
By isolating the USB relationship, you secure your Laptop from opportunity voltage spikes, ground loops, or noise generated through the linked components.
