This is the motherboard that you will design for your own purposes; the BubbleBoard will connect to it.
The photos show an example of how an Aux board would look with and without the BubbleBoard. This is a mock-up, we used a board designed for another purpose.
The components under the BubbleBoard must be low.
The inter-board spacing is dictated by the part-number of the mating-connector:
- 4mm: FX10A-140P/14-SV (Farnell 1798396).
- 5mm: FX10A-140P/14-SV1 (Farnell 1798397).
The manufacturer (Hirose) say that they are developing the following, and you may be able to source them:
- 6mm: FX10A-140P/14-SV2
- 7mm: FX10A-140P/14-SV3
- 8mm: FX10A-140P/14-SV4
