The reader initializes the interaction. The RF field is activated, and a number of other small degree instructions are exchanged to detect a compatible card.
1x GND 3V3 (P2 with 2 pins two.54mm) connector can be used to electricity externally the WCH CH569 MCU (it is usually recommended to remove the P4/SHUNT in that scenario It is far from necessary as being the 3V3 LDO IC1 is shielded towards reverse recent)
This is especially essential for the duration of debugging, tests, or reverse engineering responsibilities, exactly where accidental electrical interference could injury your Computer system or maybe the HydraBus itself.
An USB isolator acts like a barrier, avoiding any immediate electrical relationship involving your Laptop or computer and the isolated device.
