Pluto: common questions

What microcontroller does the Pluto use?

The Pluto is built around the 296-49839-1, from the TI MSP430/CC family.

How big is the Pluto PCB?

The Pluto measures 24.4 × 24.4 mm, has 2 copper layers and is 0.5 mm thick.

How many components are on the Pluto?

36 components, from 11 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 Pluto design files?

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

Can I use the Pluto design in my own project?

Yes, under the terms of its GPL-3.0 license, which carrotIndustries chose for the repository.

Can I test firmware for the Pluto without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug TI MSP430/CC firmware against it before you order a PCB.
