IS31FL3736 Development Board

This project is to develop a prototype for reviewing the IS31FL3736 12×8 DOTS MATRIX LED DRIVER WITH INDIVIDUAL AUTO BREATH FUNCTION from Integrated Silicon Solution, Inc The basic goals of this project is to create a simple board with an array of RGB leds to see what is involved to control the LEDs as per the writeup in the datasheet. Things of interest will be

Simplicity of use (firmware)
Simplicity of the layout
The effective power consumption
The footprint size.

Questions

How big is the Is31fl3736 dev PCB?

It measures 67.7 × 67.6 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Is31fl3736 dev use?

63 parts, built around the AAA3528LSEEZGKQBKS. 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 Is31fl3736 dev KiCad files?

From the SteveMayze/is31fl3736_dev repository on GitHub, at the commit this page was made from: the board is kicad/IS31FL3736_Dev.kicad_pcb and its schematic kicad/IS31FL3736_Dev.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Is31fl3736 dev design in my own project?

Its repository states no licence, so its author keeps all rights: ask SteveMayze before reusing the design.
