XK-1A Hardware Manual REV 1.1.0 2012/11/28 XMOS 2012, All Rights Reserved.XK-1A Hardware Manual 2/15 1 Introduction The XK-1A is a low cost development board intended for exploring and designing multicore microcontroller designs. It comprises a single XS1-L1 device, 128KBytes SPI FLASH memory, four LEDs and two press-button switches. Two xCONNECT Links allow you to link multiple XK-1A boards together in a chain, two I/O expansion areas are provided for connecting additional components to the XK-1A, and an XTAG-2 debug adapter can be connected to debug the XK-1A board with a PC. The diagram below shows the layout of these components on the card.

Additional boards that have been chained together may be able to be powered by the XTAG-2 (depending on the length of the chain) or from an external 5V power supply. The rest of this document provide a detailed description of these components. REV 1.1.0
