Useq1: common questions

What microcontroller does the Useq1 use?

The Useq1 is built around the RP2040, from the RP2040/RP2350 family.

How big is the Useq1 PCB?

The Useq1 measures 40.6 × 108 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Useq1?

163 components, from 73 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 Useq1 design files?

From the Emute-Lab-Instruments/uSEQ 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 Useq1 design in my own project?

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

Can I test firmware for the Useq1 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
