SEQ32: common questions
What microcontroller does the SEQ32 use?
The SEQ32 is built around the Arduino_1pin, from the AVR/Arduino family.
How big is the SEQ32 PCB?
The SEQ32 measures 101.6 × 53.3 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the SEQ32?
35 components, from 29 distinct parts. The full bill of materials is listed on this page.
Where can I download the SEQ32 design files?
From the conradv5379/SEQ32 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the SEQ32 design in my own project?
The repository has no license, so all rights stay with conradv5379. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the SEQ32 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.
