Colibri Evaluation Board
From ToradexWiki
This board is ideal for developing purpose. It provide a lot of interfaces and has a flexible jumper area. It is also equipped with an extension connector which allows to connect your own Hardware.
The schematic of this board is free available, so it is also the perfect for a reference design.
Additional to the Evaluation with a Colibri, you need:
- A power supply providing anything from 7-24V DC. In the basic configuration the Board consumes about 2Watts, but the on-board supply provides up to 5Amps on each of the 3V and 5V voltage rails.
- A USB cable (A to B)
And optionally
- A 9-pin Null-modem cable for emergency recovery (connecting to a PC running a terminal program)
- keyboard / mouse
- PC monitor

Write to LEDs read from switches
You first have to choose a free GPIO and wire up the connection from the GPIO to the connector X22 on the EvalBoard. You should remove the jumper, that the alternative function on the hardware is disconnected. A software example how to write to a GPIO can be found in SourceCode examples.
Compatibility to Colibri
The Evalboard works with all available Colibris. But some jumper have to be removed for PXA3XX or placed for PXA270. For more information see the Migration Guide.
PXA270
Make sure, that
- jumper X11-JP41 is placed and
- jumper X8-JP44 is placed.
PXA3XX
Make sure, that
- jumper X11-JP41 is removed and
- jumper X8-JP44 is removed.
