Pinout

UCF File: gecko_visual.ucf

The mechanical position of the system bus 1 connector on GECKO3main and GECKO4main is similar. Therefor only 1 connector is needed.

GECKO system bus 2 (IO-Bus 2)

The mechanical position of the system bus 2 connector on GECKO3main and GECKO4main is not identical. To make the GECKOvisual compatible with both versions of GECKO-main, two different connectors are used (refer to image on top). The assignment of the pins on both connectors is similar.
