LightFusion: common questions

What microcontroller does the LightFusion use?

The LightFusion is built around the MDBT42-512KV2, from the Nordic nRF family.

How big is the LightFusion PCB?

The LightFusion measures 61 × 42 mm, has 4 copper layers and is 0.96 mm thick.

How many components are on the LightFusion?

106 components, from 51 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 LightFusion design files?

From the drleavsy/LightFusion repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the LightFusion design in my own project?

The repository has no license, so all rights stay with drleavsy. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the LightFusion without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Nordic nRF firmware against it before you order a PCB.
