XK-1A Development Kit
The XK-1A is a low cost development board for exploring event-driven processor designs based on the XS1-L1 device. Multiple XK-1A boards can be linked together in a chain and two I/O expansion areas are provided for connecting additional components to the XK-1A. Design files for example add-on boards are available, including an SD card reader, a Bluetooth adapter and a Control Card.
The XK-1A is available as a kit with an XTAG-2 debug adapter that can be connected to the XK-1A to provide a JTAG interface to the board from a PC, or as an individual board if you want to chain multiple XK-1As together (one XTAG-2 can be used for several boards):
| Contents | Part Number | Price | Buy |
| XK-1A + XTAG-2 | XK-1A | $59 | Digikey |
| XK-1A only | XK-1A-BRD | $49 | Digikey |
The XK-1A can be powered directly from the XTAG-2 connector or from an external 5V power supply.
XK-1 and XK-1A Boards
The XK-1A board replaces the XK-1 board which is no longer available. The boards provide the same functionality apart from minor changes that are detailed in the XK-1 Development Kit Update document.
The XK-1A Tutorial can be used with the XK-1 Tutorial code for either board. The XK-1 add-on designs can also be used with either board.
