Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.
What each says it does
jitx-skills
JITX workflow skills for PCB design. Use jitx-component-modeler for component creation from datasheets. Use jitx-circuit-builder for wiring circuits, passives, and application circuits. Use jitx-substrate-modeler for capturing information about the fabrication substrate. Use jitx-physical-layout for authoring physical layout geometry from code — shapely custom shapes, copper and overlappable copper (antennas, filters, net-ties), pad features, code-placed vias and routes, and layout-intent tags. Use jitx-interconnect-constraints for signal integrity constraints, topology, differential pairs, and protocol-level constraint patterns. Use jitx-pin-assignment for pin assignment patterns including provide/require, pin muxing, DiffPair P/N swapping, PCIe lane ordering, DDR byte/bit swapping, and topology+constraint composition on pin-assigned ports. Use jitx-code-review for same-model self-critique of JITX Python code against the anti-string-hacking architectural rules — mandatory for complete-board tier at task acce
EasyEDA Copilot
AI tools for EasyEDA Pro schematics, PCB placement and routing, SPICE simulation, and DRC.
