Much progress has been made since the my last post to this thread!
Stage 2 is now more or less complete, All the hardware has been reverse engineered and new boards have been drawn up and sent off for manufacture.
A quick overview of the current status of the hardware:
Logicboard:
Port "Pack":
Keypad / Power board:
These are really "development" versions of the PCB's and will likely be altered a little for the final version but we at a point where we just need to get one of these built and make sure it works!
In particular the keypad PCB needs some attention as that massive 18650 holder will get in the way but I just wanted to PCB mount it so it isn't flapping around while I'm testing. (and I just noticed I have two 8's on the keypad, oops
)
If I have all my measurements correct these boards should all be able to be stacked and screwed together leaving enough space between the keypad and port pack PCB for the LCD module (Which will sit on a 3D printed bracket) which should make for a rather neat compact solution for testing before we have a case
