LED-Board 1x4 16bit high density

a LED Board that can be combined seamlessly to bigger lines with very high LED density (= small pixel-pitch).
It uses the TI TLC5971 Constant-Current LED-Driver Chip with 16bit dimming resolution (HTSSOP-20 housing).
The LED-Type used is Nichia NSSM124D - these are available as cut-tape from an distributor.

The thing is designed to be hand-soldered.

Project-Status

design phase

TODO

fix pads that are to small for hand-soldering
order updated PCB's
solder some more boards

Technical Information

every controller chip (TLC5971) has 12 ConstantCurrent outputs. so every LED is controllable individual.

Questions

How big is the LEDBoard 1x4 16bit highdensity PCB?

It measures 12.3 × 7 mm and has 2 copper layers, 1.6 mm thick.

What parts does the LEDBoard 1x4 16bit highdensity use?

10 parts, built around the TLC5971PWP. 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 LEDBoard 1x4 16bit highdensity KiCad files?

From the s-light/LEDBoard_1x4_16bit_highdensity repository on GitHub, at the commit this page was made from: the board is LEDBoard_1x4_16bit_highdensity.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the LEDBoard 1x4 16bit highdensity design in my own project?

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