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.
It can easily be achieved by utilizing display modules that have a capacitive touch with Cover Lens Bezel (CLB) which can provide sufficient protection given that the perimeter is sealed.
For applications that use resistive or non-touch display module, the best practice is to add a thin transparent membrane that can be effectively fused to the enclosure and then place the display in front of it.
The membrane must be clear and flexible enough for use with the display. Likewise, just using sealants around the edges is not a good way as it can affect touch capability.
The 30-way Flexible Flat Cable has the following specifications:
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.
A module with its part number starting with SK means it’s a Starter Kit.
A Starter Kit is a display module with a set of accessory parts, which are designed to aid the starting out of development with the 4D Systems product in question.
For example, a SK-GEN4-43DCT is a Starter Kit for the gen4-uLCD-43DCT display module and includes extra parts such as a 4D-UPA Programmer and a microSD Card.
All of our Goldelox-based display modules have onboard protection diodes and 3.3V regulators, they have forward voltage drops. Therefore you ‘need’ to provide 5 volts to the display modules.
That being said, it is possible to power Goldelox modules down to around 4V, sometimes a little lower. By powering the 5V pin as normal there is a diode in series for protection, but by powering the 5V_OUT pin, this is after the diode, so a slightly lower input voltage can be tolerated. Refer to the Schematic in the module Datasheet to see what is actually happening. It will get to a point where the 3.3V regulator will no longer be regulating, and will simply pass the input voltage, however, the module may still run correctly. You may have success at 3.3V using the 5V_OUT pin as the input, however, you will need to test this yourself. This is not endorsed by 4D Systems, but you are welcome to try at your own risk.
You can usually find 3D Models in the downloads section of each product page.
If you cannot find any, please contact the support team to check if it is available.
Yes. The display breaks out the available pins from the display module.
However, keep in mind that these products are primarily meant to program the displays, and breaking out the extra pins is an additional feature.
On that note, the 5-way interface included in both programming adaptors is labeled:
is meant to program uLCD and uOLED products, not to breakout the display’s 5-way interface.
Therefore, if you need to breakout the Serial UART pins that are also used for programming, it is recommended to use a gen4-Breakout board or integrate the display directly into your application board.
-AR and -PI are suffixed to part numbers which indicate the display module in question is in a Kit for Arduino (-AR) or the Raspberry Pi (-PI).
In the kit will be the display module in question, plus (but not limited to) the Arduino Adaptor Shield (for -AR) or the Serial Pi Adaptor (for -PI).
For example, uLCD-43DT-AR is a uLCD-43DT display module in Kit form to includes parts to interface easily with an Arduino.
The display module used is identical whether you buy the display module by itself, or you buy it in the -AR or -PI kit forms, the kits just include some extra parts for easy interface, while the display module by itself does not.
