Two small green circuit boards with gold 50-pin connectors and micro USB ports

Ruth's sister 2pcs Mini drive control board 50PIN 800*480 LCD internal power cable

SKU CH-2S8M-RBDSY

Two mini drive control boards with 50-pin gold-plated connectors power 800×480 LCD panels from a 5 V micro-USB supply

  • Powers LCD panels via Micro USB 5V 1.5A supply
  • Drives LED backlight up to 10V with 180mA max current
  • Accepts HDMI 1.2 input through gold-plated Mini connector
  • Compatible with 50-pin 800×480 screens from 6.5 to 10.1 inches
  • Two boards included for dual-panel or spare-part flexibility

Compatible LCD Panels

This drive control board kit suits 50PIN panels including AT065TN14 AT070TN90 AT070TN92 AT070TN94 AT080TN64 and AT090TN10. It targets repair technicians and hobbyists who need to power 800 by 480 screens from a 5V USB source. The boards accept HDMI input and switch to that channel automatically when a signal is detected.

Replacing Damaged Controller Boards

The pair replaces failed or missing driver boards on 6.5 to 10.1 inch TTL panels that use the same 50PIN gold plated FPC connector. The upgrade is worthwhile when the original board no longer drives the LED backlight or the HDMI input has stopped switching automatically.

Straightforward FPC Connection

Each board measures 5.2 by 4.6 centimetres and plugs directly into the panel FPC socket without extra cabling. A micro USB port supplies 5V at greater than 1.5A while the on board circuit drives backlight voltages up to 10V at 180mA. Incorrect FPC orientation or an underpowered USB source are the most common issues.

Questions about this item

What are the board dimensions and the 50-pin connector pitch for fitting inside my device?

The drive board measures 5.2 cm by 4.6 cm by 6 mm and uses a 50-pin gold-plated FPC seat designed for compatible LCD panels.

How do I connect power and video, and which step do builders often miss?

Supply 5 V at over 1.5 A through the micro-USB port, plug HDMI into the HD-I input for automatic signal switching, and insert the panel FPC into the 50-pin gold-plated connector with the correct orientation.

What backlight current limit should I watch for when the panel ages?

The on-board driver is rated for a maximum of 180 mA LED backlight current at up to 10 V; ensure your replacement panel stays within that limit.
