15dot4tools Hardware: RavenUSB

The RavenUSB is the USB Stick present in Atmel’s RAVEN Kit. This also gives you two end-nodes to experiment with. The kit is available at a cost of $99 USD, search part number ATAVRRZRAVEN .

You can also buy just the USB stick, ATAVRRZUSBSTICK . This does NOT include the JTAG adapator I think (the RavenUSB uses 50-mil connectors), but you should be able to bootload the USB stick without it.

Programming Tools

The default firmware includes a simple bootloader. However you may find it useful having an external programming, in case something goes wrong.

Two official Atmel tools can be used for programming, which are available from the above distributors:

• The Atmel JTAG MK-II can be used for programming AND debugging. Order code ATJTAGICE2, costs $300 USD.
• The Atmel Dragon can be used for programming only. On AVR devices with less than 32KB of flash it can also be used as a debugger. Order code ATAVRDRAGON, costs $50 USD.

Other tools can be used for programming or debugging:

• JTAG MK-II Clones, which are cheaper but may cause trouble (see:http://ww2.kludgeguru.com:8080/blogs/eeblog/?p=570])

Be careful of simple Atmel JTAG programmers, and a very wide range of clones available. These devices do not typically support newer devices such as the AT90USB1287, so they will not work.
