smol, a 0.35mm pitch WLCSP12 STM32C011D6 footprint. 1.7mm x 1.4mm package. C2&D3 are epoxy filled via-in-pad as they are unroutable w/o that. I have its physically bigger cousin running Ada in 16k of flash with only 6k ram. This one has 32k, woo hoo.

Worked! SWD connected. For soldering, a very thin layer of flux was added to the footprint. Then two hotplates, one at 150c for 90s another at 250c for 30s. All in all, quite straightforward.
