Introduction
This project is a I2C device to control up to three High Power LED drivers using three PIR13 motion controllers.
The LED drivers in question are already provided on my site and are the SLV 464110 10W 3-36V (EAN: 4024163087155) constant current High Power LED drivers - as are the motion detectors PIR13 modules from ELV.
The device will be designed around the ATTINY20-SSU micro-controller. The requirements being SPI for In System Programming, I2C to connect to the master device and GPIO for the three High Power LED drivers and the three PIR13 sensors.

Questions
How big is the Tl2c PCB?
It measures 120.7 × 127 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Tl2c use?
95 parts, built around the ATTINY20-XU, LF120ABDT-TR, TPS70933DBV and IRLML2502. 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 Tl2c KiCad files?
From the SteveMayze/TL2C repository on GitHub, at the commit this page was made from: the board is kicad/Controller/tl2c.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tl2c design in my own project?
Its repository states no licence, so its author keeps all rights: ask SteveMayze before reusing the design.
