Electronics for a compact cultural lamp.

Two lighting channels

The design uses five common-anode dual-color LED placeholders with separate white and warm channels. Each LED color has its own current-limiting resistor. The final LED package and pin order remain to be confirmed.

Touch interaction

Planned sequence: white → warm → off, with a spring touch electrode. Firmware, touch-library integration and enclosure sensitivity tuning remain pending.

USB-C and battery power

The candidate combines USB input, a single-cell lithium charging circuit and a USB-priority power path. The engineering notes specify a nominal 3.7 V / 120 mAh protected battery and an initial charging target of about 30 mA, subject to cell and bench verification.

Editable design. Clearly identified views.

V0.5 contains 55 footprints, 412 track segments and 35 through vias. The supplied 3D views include placeholder LED, USB and touch-spring models. Board width, component fit and enclosure clearances require physical confirmation.

What the package checks establish.

The figures below are taken from the supplied engineering records, dated 23 October 2026. They were not rerun for this website publication.

PCB connectivity0 unconnected items in the supplied report
Design rule check0 errors; 1 USB footprint-library mismatch warning
Schematic checkNo violations reported; inspect the ERC JSON for configured checks
FirmwareNot implemented, compiled or programmed in these packages
Prototype validationV0.5 assembly, touch, charging, thermal and optical tests pending
Manufacturing filesNo production Gerber release included

Before a build: confirm the LED polarity and pad numbering, USB connector and touch-spring dimensions, battery protection and charging conditions, and the final enclosure fit.
