iCE40HX1K USB Molecule

Lattice iCE40HX1K-VQ100 FPGA (1280 LUTs) with USB-C power + data on an Adom molecule. Open-toolchain target — yosys + nextpnr + icepack. 30 GPIO machine-pin contacts to the workcell.

How it works

This molecule is authored in tscircuit (TSX) and rendered through
adom-tsci for the interactive 3D viewer + Components / Nets HUDs +
Walkthrough Demo. The board source — lib/index.tsx,
package.json, walkthrough — ships as a downloadable source bundle
on this page. Untar it and run bun install && bunx tsci build to
recreate the GLB / PCB / schematic from source.

Live 3D viewer

Open the interactive viewer above to orbit the board, click any
chip for refdes + footprint, run the Walkthrough Demo, or open the
Nets HUD for the auto-glow x-ray view.
