The current PCB layout has footprints for the three XLR sockets on one end and volume on the other, I have decided that switches for 'CALL' and 'TALK' can be panel mounted so any builder can choose their own style. I found some illuminated pushbuttons, one latching, one non-latching. If my idea has any footing in reality I just have to drill three round holes in each end of the case. I remember somewhere in the original BlueClone thread some difficulty in finding the specified button so this will allow a bit of leeway.
The PCB is designed to fit in the same aluminium case as the BlueClone.
