My main issue at the moment is how to do the microcontroller, I can either use a Teensy 2.0++ and try and figure out how to fit that in the case as I can't use the Teensy 2.0 without using pin PD6 which has an LED on it and that is known for causing issues, unless if I put scroll lock on there(which I don't know if that will be trouble free as it just needs to supply current to the scroll lock LED). These two solutions have an issue with how much space is available in the case and due to the plate, and I am not sure if the 2.0 can fit, let alone the 2.0++.
I can integrate the mc onto the PCB and have it assembled like that but the price goes up quite a bit compared to a separate mc. But total cost should go down from what I can see by maybe $5 per PCB, not including the shipping of the teensy. The downside is programming isn't nearly as easy as a teensy is, but I will leave that up to everyone.
Board will support the similar to my omnikey PCB, but will include support for different bottom rows: Top: Bottom: Tentative Pricing:(not including final shipping: $10 - $15 in US, more for international)
- 10 - $65
15 - $55
20 - $50
30 - $45
40 - $40
Only other questions I have is do the cases for the AT101, AT101W and SGI granite all have the same mounting? Would a PCB from one fit into the other two? Or is there slightly different mounting between them? I only have access to AT101W's at the moment.
