DataDisplay: common questions

What microcontroller does the DataDisplay use?

The DataDisplay is built around the INA180A1, from the AVR/Arduino family.

How big is the DataDisplay PCB?

The DataDisplay measures 38.1 × 69.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the DataDisplay?

30 components, from 24 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 DataDisplay design files?

From the nunosousa/TelescopeMirrorTester 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 DataDisplay design in my own project?

Yes, under the terms of its MIT license, which nunosousa chose for the repository.

Can I test firmware for the DataDisplay without the hardware?

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