PiUPS: common questions

What microcontroller does the PiUPS use?

The PiUPS is built around the ATTINY1634-S, from the AVR/Arduino family.

How big is the PiUPS PCB?

The PiUPS measures 65 × 56.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PiUPS?

82 components, from 28 distinct parts. The full bill of materials is listed on this page.

Where can I download the PiUPS design files?

From the Blake-Robotics/PiUPS repository on GitHub, which has the KiCad layout; 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 GPL-2.0 license, which Blake-Robotics 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 AVR/Arduino firmware against it before you order a PCB.
