GECKO3basic

This is a module for fast prototyping of application specific circuits.

On the bottom side is a connector for the first system bus connector. On the top side you can decide if you prefer a bread board or a solder point array to build your circuit.

If you want to provide power to the GECKO4, you need to make some modifications. See below.

GECKO3basic with breadboard GECKO3basic with solder point array

If you want to provide power to the GECKO4 you have to connect the second block of power pins. Connect them as shown in the picture (black lines).

There is one connector on top of the board which is used to easily connect system bus signals with components on the bread board. If you use the solder point array there is a row of solder points connected to the same signals as on the top connector. The pinout for both is the same and on the PCB there are orientation marks to help you finding the right pin.
