LAMPED
About the LAMPED PCB
LAMPED is an open source PCB design by Gabouin, published on GitHub under the MIT license. It is a 2-layer board measuring 50.9 × 65.7 mm, with 16 components from 7 distinct parts.
By type, the board carries 10 diodes, 3 resistors and 1 connector.
From the project
A simple, desk-friendly LED “lamp” built around the LM3914 LED driver: a 10‑LED circular array that lights up progressively based on a potentiometer input. Powered from 5V USB, designed in KiCad, and ready for fabrication (Gerbers + BOM + pick&place included).

Key points: - 10 LEDs in a circular pattern - LM3914 handles the LED level display logic - USB 5V power (USB-A connector footprint on the board) - Designed in KiCad - Includes production outputs for fabrication & assembly
