About the Programmable light PCB

Programmable light is an open source AVR/Arduino PCB design by dilshan, published on GitHub under the MIT license. It is a 2-layer board measuring 52.2 × 79 mm, with 50 components from 31 distinct parts.

Its main chip is the ATmega8L, from the AVR/Arduino family. Other key parts include the DS1307Z+T&R, MC34063AD and SSD-COM-CAT. By type, the board carries 20 resistors, 8 capacitors, 6 transistors, 4 ICs, 3 connectors and 3 switches.

From the project

Simple time based programmable light controller

This light controller is based on ATmega8 microcontroller and DS1307 real time clock. It is designed to handle commonly available 24V - 7W LED modules.

This is certified open source hardware project. All the design files, documentation, firmware source code are available to download at the project source repository. All the content of this project are distributed under the terms of the following license:

Programmable light: common questions

What microcontroller does the Programmable light use?

The Programmable light is built around the ATmega8L, from the AVR/Arduino family.

How big is the Programmable light PCB?

The Programmable light measures 52.2 × 79 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Programmable light?

50 components, from 31 distinct parts. The full bill of materials is listed on this page.

Where can I download the Programmable light design files?

From the dilshan/programmable-light repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Programmable light design in my own project?

Yes, under the terms of its MIT license, which dilshan chose for the repository.

Can I test firmware for the Programmable light 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.
