Over the last few weeks, I've done a lot of work on the firmware and digit design. I spent time refactoring the codebase and fixing minor bugs and adding features.
I've also just launched beautiful, brand new digit blocks. These solve every problem with the old digit slides -- they are more clear, stand completely vertically, and more importantly, don't wobble around at all.
I also have taken the sad step to remove BLE support from the firmware for a couple of reasons: First, the app has never worked correctly on Android, and second, I am not going to be using the Redboard Nano for much longer.
Thanks for reading!
