PiUPS: common questions

What microcontroller does the PiUPS use?

The PiUPS is built around the Raspberry_Pi_2_3, from the Raspberry Pi family.

How big is the PiUPS PCB?

The PiUPS measures 87.4 × 56 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PiUPS?

110 components, from 47 distinct parts. The full bill of materials is listed on this page.

Where can I download the PiUPS design files?

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

Can I use the PiUPS design in my own project?

Yes, under the terms of its CERN-OHL-W-2.0 license, which diminDDL chose for the repository.

Can I test firmware for the PiUPS without the hardware?

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