The "Final Beta" Revision of K1 has been pushed up to GitHub.
List of Changes:
1. Added Dual NOR gate and Inverters from testing on K16 to improve result capture.
2. Changed PIC to use QFN version.
3. Added 2mm holes for fastening heat sink.
4. Made both LEDs flashable under software control for better blinkies.
5. Added thermistor for sensing temperature.
6. Fixed issues with buck regulator traces.
7. I2C chain conn. now non-thru hole pads - fits 3 pin header.
8. Added ferrite beads to ASIC power and USB signals.
9. Added another PIC decoupling capacitor.
This design should be checked over carefully before ordering boards based on it. Due to the many changes it should be treated as a new board.
I am initially only going to order a short run of these boards to supply current web store DIY orders and my own initial testing. This "Final Beta" board will be WHITE.
PIC QFN parts are in short supply right now. I have a limited batch coming to me already and have sold about 1/3 of those via web store pre-orders for the pre-programmed PICs.
Here's a render of what the Beta White board could look like:
And the back side - for those who want to know where the LEDs are. Actually I think the back side will be white too.
