What is the specification of the provided 30-way FFC?

The 30-way Flexible Flat Cable has the following specifications:

  • No. of Pins: 30
  • Length: 150mm
  • Pitch: 0.5mm (0.02")
  • Cable Type: AWM 20624 80C 60V VW-1
  • Heat Resistance: 80 °C
  • Connections on the opposite side at each end: Type B

All 30-way FFC connectors provided for gen4 displays are ‘Top Contact’, meaning the FFC cable has the metal ‘fingers’ pointing upward in the connector, blue stiffener on the back of the FFC cable is down on the PCB side.

It is best to check with our sales team if we can provide compatible flex cables based on your length requirements.

I need a longer 30-way flex cable, where can I find some?

The standard length of FFC cable we include in our gen4 products is 150mm (4DFFC-150) which is usually just right for common applications.

We can also provide you with 200mm (4DFFC-200) for a longer alternative. If you are interested, you can add a note in your order that you would like this option.

The 4D-UPA/gen4-PA interferes with when I use COM0 of my display, what can I do?

When 3 devices are connected to each other through the same UART lines, the third device can interfere with the communication between the other two.

Ideally, only one set of UART pins is connected to another. That means you can either:

  • Use a gen4-IB which breaks out the 5 commonly used pins (5V, TX, RX, GND, RST)
  • Use a gen4 Breakout board which breaks out all 30-pins from the 30-way FFC
  • Connect the FFC directly to your application board
