Backlight controller 6x3: common questions
What microcontroller does the Backlight controller 6x3 use?
The Backlight controller 6x3 is built around the DEV-14056, from the NXP family.
How big is the Backlight controller 6x3 PCB?
The Backlight controller 6x3 measures 140.3 × 67.3 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Backlight controller 6x3?
87 components, from 19 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Backlight controller 6x3 design files?
From the janelia-kicad/backlight_controller_6x3 repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Backlight controller 6x3 design in my own project?
It is published under Custom license, which limits how it may be reused; read the license before building on it.
Can I test firmware for the Backlight controller 6x3 without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug NXP firmware against it before you order a PCB.
