Display: common questions

What microcontroller does the Display use?

The Display is built around the LPC1785FBD208_551QFP50, from the NXP family.

How big is the Display PCB?

The Display measures 87.3 × 60.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Display?

58 components, from 27 distinct parts. The full bill of materials is listed on this page.

Where can I download the Display design files?

From the usevolt/display repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Display design in my own project?

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

Can I test firmware for the Display 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.
