Mazzy: common questions

What microcontroller does the Mazzy use?

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

How big is the Mazzy PCB?

The Mazzy measures 116 × 93.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Mazzy?

100 components, from 42 distinct parts. The full bill of materials is listed on this page.

Where can I download the Mazzy design files?

From the jaspermayone/mazzy-pcb repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Mazzy design in my own project?

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

Can I test firmware for the Mazzy 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.
