Spectrum one: common questions

What microcontroller does the Spectrum one use?

The Spectrum one is built around the Copper Keepout Zone, from the ESP32 family.

How big is the Spectrum one PCB?

The Spectrum one measures 170 × 57.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Spectrum one?

15 components, from 6 distinct parts. The full bill of materials is listed on this page.

Where can I download the Spectrum one design files?

From the currenari-lab/spectrum-one repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Spectrum one design in my own project?

Yes, under the terms of its CC-BY-4.0 license, which currenari-lab chose for the repository.

Can I test firmware for the Spectrum one without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
