Got a Raspberry PI B+ and need a downverter? Drop me a note.
Adafruit will be shipping their version 'soon', but if you're in the UK and can't wait, I've got enough connectors and cable to put together a few.
For the next few days I will make one up and post it to you first class within the UK for £4.50 including postage and packing. (I'm not VAT registered so there is no VAT to pay). Drop me an email at firstname.lastname@example.org.
