About the Card v0.1 PCB

Card v0.1 is an open source STM32 PCB design by northernpaws, published on GitHub under the CERN-OHL-S-2.0 license. It is a 6-layer board measuring 67.6 × 35.4 mm, with 189 components from 43 distinct parts.

Its main chip is the STM32H747XIHx, from the STM32 family. Other key parts include the IS42S16160J-7BLI, CS42528K-CQZ and NJM4580E-TE1. By type, the board carries 86 resistors, 82 capacitors, 10 ICs, 9 connectors and 2 crystals.

It belongs with the audio and dev boards & breakouts designs in this gallery.

From the project

Embedded Rust hardware and software ecosystem for audio and MIDI processing.

Catalina is an embedded-first Rust ecosystem for building music and audio processing devices, with a primary focus on ARM Cortex MCUs as the end-target.

The ecosystem is comprised of: A Rust crate providing a DSP and audio engine designed for embedded devices (heapless by default, small footprint). Various composable interfaces for quickly prototyping new instruments. Drivers for common audio codecs, SDRAM, etc. Windows, MacOS, and Linux support for developing audio chains before flashing to hardware. Future web interface for synth design, with WebUSB for direct device flashing. Two base…

Card v0.1: common questions

What microcontroller does the Card v0.1 use?

The Card v0.1 is built around the STM32H747XIHx, from the STM32 family.

How big is the Card v0.1 PCB?

The Card v0.1 measures 67.6 × 35.4 mm, has 6 copper layers and is 1 mm thick.

How many components are on the Card v0.1?

189 components, from 43 distinct parts. The full bill of materials is listed on this page.

Where can I download the Card v0.1 design files?

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

Can I use the Card v0.1 design in my own project?

Yes, under the terms of its CERN-OHL-S-2.0 license, which northernpaws chose for the repository.

Can I test firmware for the Card v0.1 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
