- Add pull-up on SS
- LP filter/ isolation on SPI line (noticable cross-talk)
ice40 chip used with 3.3V I/O pins and 1.2V core. Chip is not 5V tolerant.
The logic level shifter chips have both 5V and 3.3V. The TI 74LVC chips require that VCCA by power up before, or with, VCCB.
All level shifters VCCA==3.3, VCCB==5
Strictly speaking level shifters not needed for 3.3V -> 5V.

Questions
How big is the Icedaq PCB?
It measures 64 × 55 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Icedaq use?
74 parts, built around the ICE40HX1K-VQ100 and MCP6004-E/P. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Icedaq KiCad files?
From the mdavidsaver/pcb repository on GitHub, at the commit this page was made from: the board is icedaq/icedaq.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Icedaq design in my own project?
Its repository states no licence, so its author keeps all rights: ask mdavidsaver before reusing the design.
