Backplane: common questions

What microcontroller does the Backplane use?

The Backplane is built around the ARDUINO_MICRO, from the AVR/Arduino family.

How big is the Backplane PCB?

The Backplane measures 121.9 × 88.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Backplane?

99 components, from 12 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 Backplane design files?

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

Can I use the Backplane design in my own project?

Yes, under the terms of its CERN-OHL-1.2 license, which greyltc chose for the repository.

Can I test firmware for the Backplane 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.
