Kanga / m0xpd DDS Shield

I'm pleased to be able to report that the m0xpd DDS shield has been made ready for sale and will soon be available from Kanga-UK...

The schematic is very much similar to that previously reported on this blog - retaining the on-board generation of quadrature square-wave outputs, which allow operation with Software Defined Radios.

In addition to the 0.1 inch header carrying all the oscillator signals, the board also has a BNC output socket making a handy hook-up option for those who want to use it in e.g. a signal generator. 

Here, in the open-source spirit fundamental to the Arduino platform, is the schematic...

To show what it can do, I've put together a VFO system which is rather more fully-featured than the previous version, offering multi-band, multi-mode support, Receive Incremental Tuning, IF offsets, memory, etc...

The new VFO is described over on the "Kanga Resources" page.

I'll let you know when Dennis gets the new DDS shield up on the Kanga website, so you can send in your order HI HI.
