A custom ATmega328P controller board for WS2812B addressable LED strips, designed in KiCad and built for a light box. Three buttons and a brightness knob drive three lighting modes, from adjustable warm/cool white to six animated "party" effects, all running on a standalone Arduino-compatible board with no dev board required.

- Standalone ATmega328P (DIP-28) running at 16 MHz, fully Arduino-compatible - Three lighting modes selectable with a dedicated MODE button - Analog brightness control via an on-board potentiometer, with smoothing to avoid flicker - Six animated effects in Party mode…

LED-PCB-Controller: common questions

What microcontroller does the LED-PCB-Controller use?

The LED-PCB-Controller is built around the ATmega328P-P, from the AVR/Arduino family.

How big is the LED-PCB-Controller?

The LED-PCB-Controller measures 44.5 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the LED-PCB-Controller?

21 components, from 14 distinct parts. The full bill of materials is listed on this page.

Where can I download the LED-PCB-Controller design files?

From the audy910/LED-PCB-Controller repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the LED-PCB-Controller design in my own project?

The repository has no license, so all rights stay with audy910. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the LED-PCB-Controller without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
