Hi All, I've just generated a PDF file containing the component overlays, connector positions and mechanical dimensions of the Balloon 3 PCB. It's intended to be of use to people who are building daughterboards and need to know where the connectors are. You can see it at http://www.solidlights.co.uk/balloon/Balloon_3_0V1_Overlay_Top_And_Bottom.pdf Chris -- Chris Jones - chris@martin-jones.com Martin-Jones Technology Ltd, makers of Solidlights http://www.solidlights.co.uk/
