Sorry about that! These are definitely not cancelled, just delayed a short bit. We got swamped around Nov - Dec so we decided to push this off a little bit. But we are very close to releasing these very soon, likely via a Kickstarter early next month.
There will be a new processor board released (basically the TinyScreen+ without the screen), which will have a 32-bit SAMD ARM processor (essentially the Arduino Zero, but smaller), along with a whole new line of tiny boards (30+), which connect to the system via small 5-pin cables, allowing for a lot more flexibility with making miniature projects. These will be lower cost, and also work with other boards, like a standard Arduino, Raspberry Pi, and most other standard microcontroller systems.
Looking forward to getting these out soon, so keep watching. We should be promoting this more over the next month as we lead up to the release.
Thanks,
Ken
