1. The USB interface adopts PH1.25 definition and 5V, D-, D+, GND standard definition.
The definition of 4P is as follows (the front side of the PCB has silk screen printing 1-6, and the back side has definitions)
1 5V touch screen signal
2 D-Touch screen signal
3 D+ touch screen signal
4 GND touch screen signal
================================================== ==========
2. The input is a double-sided FPC socket with a pitch of 6P-0.5. You need to confirm the ordering before use. Illegal operations such as reverse connection may cause burn-in and the loss may be irreparable.
The definition of 6P is as follows, (there are silkscreens 1-6 on the front of the PCB and definitions on the back)
1 RES touch screen signal
2 3.3V touch screen signal
3 GND touch screen signal
4 INT touch screen signal
5 SDA touch screen signal
6 SCL touch screen signal

Recommended usage of this product:
Because this product has a very small operating current and basically no heat, it can be directly pasted to a suitable area with 3M glue, but you need to pay attention to the insulation problem on the back.

1: This product also supports Bluetooth transmission. The Bluetooth standard needs to support BLE5.0 or above. Version 4.2 of some devices can also be used, but if it is lower than version 5.0, you need to actually test it yourself. This function is a customized function and is not a default function. Relevant technical parameters need to be confirmed in advance
2: 3.3V GND is marked on the back, which is an alternative power input when using the Bluetooth BLE function and not using USB power supply. No matter what the situation, please do not use it as an output.
