This is an adapter board for breaking out the GPIO or LCD pins on the A10-OLinuXino-LIME, A10-OLinuXino-LIME-4GB, A20-OLinuXino-LIME or A20-OLinuXino-LIME-4GB board. You'll also need the CABLE-40-40-10CM 2×20-pin 0.05"-pitch ribbon cable to connect this adapter to the LIME.

NOTE: This is only for the original LIME boards mentioned above. It will not work on LIME2 boards. A new adapter is expected to be available soon for the LIME2 models.

When connected to GPIO1 of the LIME, it provides a UEXT port so you can connect a UEXT module to add functionality to the LIME. It also breaks out the GPIO port pins to a 0.1"-pitch IDC connector and to 0.1"-pitch pin header pads. Pins are included that you can solder to the pads.

When connected to GPIO2 or GPIO3 of the LIME, the GPIO pins are broken out as explained above (but UEXT is not available).

When connected to the LCD port of the LIME, the LCD signals are broken out, and you can connect any of the A13-LCD modules to the adapter's 2×20-pin IDC port via a CABLE-IDC40-15cm 2×20-pin 0.1"-pitch ribbon cable.

Thus, to connect an LCD to the LIME, you would connect a CABLE-40-40-10CM between the LIME's LCD port and this adapter, then connect a CABLE-IDC40-15cm between this adapter and the LCD module. (Note that the A10 LIME has been tested to work with the 4.3-inch, 7-inch and 10.1-inch A13-LCD modules; it does not work reliably with the 15.6-inch A20-LCD module.)

However, if all you want to do is connect an LCD, there are newer LCD-OLinuXino displays available that have a direct compatible interface; you can just use one 0.05"-pitch CABLE-40-40-10CM to connect to those displays without needing this adapter.
