Kt sound: common questions

What microcontroller does the Kt sound use?

The Kt sound is built around the ATSAMD11D, from the Microchip SAM family.

How big is the Kt sound PCB?

The Kt sound measures 89 × 124.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Kt sound?

192 components, from 41 distinct parts. The full bill of materials is listed on this page.

Where can I download the Kt sound design files?

From the kairotronix/kt_sound_pcb repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Kt sound design in my own project?

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

Can I test firmware for the Kt sound without the hardware?

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