The bare boards just arrived, right on schedule! The first step was to bring-up the board to the demo state I had tested on the breadboard. It's all working as expected with the following functionality so far:

• Power switch selects battery or USB power
• Battery charge manager
• Battery voltage sensing
• OLED Display
• LED Matrix
• Reed switch
• Teensy LC

The form factor feels about right and the next steps are:

• Bring the driver matrix to life by populating some more components
• Weave the cores
• Mount the LED Array

So far, an exciting and fast start for me. I'm very pleased with the results so far.
