Phased: common questions

What microcontroller does the Phased use?

The Phased is built around the RaspberryPi_Pico_W, from the Raspberry Pi family.

How big is the Phased PCB?

The Phased measures 75 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Phased?

71 components, from 20 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 Phased design files?

From the kskwon02/open_echo repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Phased design in my own project?

The repository has no license, so all rights stay with kskwon02. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Phased 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.
