Interface function description
| HD-MI | HD-MI input | HD-MI standard is 1.2 |
| USB1 | power input | 5V |
| J4 | power input | 5V |
| CON8 | Touch output port | Screen corner direct access |
| CON6 | TTL-50PIN signal output | Definition reference AT070TN92 |
Features
1. Mirco USB power supply interface, 5V standard power supply, needs to be greater than 1.5A.
2. No buttons and no remote control. It will automatically switch to HD-MI channel after plugging in HD-MI.
3. 1 channel HD-MI signal input, and this IC supports HD-MI 1.2
4. HD-MI is a high-quality MINI gold-plated base.
5. The screen interface adopts high-quality gold-plated connector-50PIN-AT070tn92 definition.
6. USB --DM+DP signal can be externally expanded.
7. The driver board adopts a special circuit design that can drive LED backlights within 10V and supports a maximum current output of 180MA.
9. Support TTL signal output.
It can support common 50PIN 6.5” 7” 8” 9” 10.1 inch LCD screens such as AT070TN92.
This driver board adopts full SMD technology. The relevant parameters are designed according to industrial standards, and the shipping standards are according to civilian standards.
10. This driver board uses a double-sided gold-plated special FPC seat. The FPC does not distinguish between upper and lower connections and can be used directly.
Transportation, storage, usage requirements
1. Do not apply heavy pressure or bend deformation.
2. Anti-static and water resistant
3. Relative humidity <80%
4. Operation Temperature: -1~60℃
5. Operation humidity: 0~40℃
