I have the two-part with XMEGA target and would like to get an additional compatible ARM target board. There doesn’t seem to be a ready-made one available. Can someone direct me to some instructions for buying/modifying/building one?
Your best option is to buy the CW308 UFO board. You can use that with your existing two-part CW1173. It comes with an ARM target (STM32F3) and provides a platform onto which you can add several low-cost targets (http://store.newae.com/cw308-ufo-targets/).
Thanks. A fairly pricey option compared the the cost of the CW1173 in the first place, but looks very flexibile. I’ll look into it.
