README
README.mdSunshine DMX512 Controller Board
Controller board for DMX512 compatible lighting fixtures, built around the ARM Cortex-M4 processor (STM32F411RET).
On the hardware side, there are of four PCB:s, a main board containing the microcontroller as well as DMX512, USB USART and power circuitry. Other boards contain buttons, LCD, potentiometer sliders and similar. See the Kicad project files for details.
The software is built using the STM32 hardware abstraction layer (HAL). Aside from hardware drivers for the various input devices, it contains DMX512 generation and a simple menu system for the LCD.

Questions
How big is the Lab1 PCB?
It measures 104.7 × 55.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Lab1 use?
96 parts, built around the MAX481CSA, FT232RL, 24C16 and UA78M05IDCY. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Lab1 KiCad files?
From the jsjolund/dmx512-controller-board repository on GitHub, at the commit this page was made from: the board is PCB_Designs/MainBoard_PCB/Lab1.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lab1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask jsjolund before reusing the design.
