I think it is important to point out that the information on the Balloonboard web site is preliminary and has been derived form the first issue of the data sent for manufacturing the initial prototype. These boards are currently being built but have not been debugged. The next iteration of the board may look different, although we will endeavour to keep the connectors in the same places this can't be fully guaranteed at this stage. (For example one connector has been removed to make routing easier on the first proto). There are several outstanding design issues that need to be resolved and any one of these could impact on the placement of parts. However having said this the info on the web site gives a good idea about what L3 will look like. David Bisset iTechnic Ltd
