-------------- 1.3 C5/C4/C4L interface description --------------

USB-C male: USB-C 24P input male
USB-C Female: USB-C 24P Output Female
USB-HID: USB-C 16P connection and upgrade female socket / C port temperature probe can be connected
Note: The USB-C interface temperature probe is under development
24P pass-through, support PD3.1, USB4, lightning charging and data transmission
(Note that C4L can withstand up to 36V, C4 can be connected to 50V Thunderbolt and USB4 peripherals)
Please note: In the pass-through mode, the screen will not light up when the PD charging head is directly inserted~
When decoy testing 5A, EPR's PD charging head
A 5A data line or PD3.1 EPR data line needs to be connected behind (otherwise only 3A and no 28V)
