Vendor's Description: 

The XK-1 will be released to users who make it through to the next round of the XMOS challenge. With the XK-1 users can actually implement their project proposals.  This board is currently not available to the general public for purchace just yet. If this board is of interest to you, and you were not involved in the XMOS challenge, please feel free to contact us to register your interest.



The joy of many XK1 devices

The XK-1 is a low cost development board intended for exploring and designing event-driven processor designs based on the XS1-L1 device. Multiple XK-1 boards can be linked together in a chain and two I/O expansion areas are provided for connecting additional components to the XK-1. An XTAG-2 debug adapter can be connected to the XK-1 to provide a JTAG interface to the board from a PC. The XK-1 can be powered directly from the XTAG-2 connector or from an external 5V power supply.

Each XK-1 Development Kit includes an XK-1 Development Board and XTAG-2 Debug Adapater.

Development Tools


UPDATE: The 9.9 version of the XMOS Development Tools is now available:


It is VITAL that XK-1 users use this release or above as the XK1 is not supported in previous versions.

 As for anyone else - you will probably appreciate some of the cool new features:



Still linear, but in the shape of a cube.

Please note - this is still a linear chain of XK1's - but in the shape of a cube. Potentially useful for using many XK1s in a tight space, and it looks cool, so I thought I would post it.

Excellent! I love the idea of being able to daisychain them together.

Do you know the physical dimensions of the board and the size of the barrel connector?

The green board part is 50mm x 50mm in size.
does it need a bootloader or whatever(dont fully understand bootloaders)
There is no bootloader, it will use the JTAG dongle to upload. You will need to download the free development tools from the website.
dude that is too cool...
I am glad you approve! More exclusive photos to be posted soon. Keep a look out! Please vote if you like this product!
