From the project

Version 0.1.0-alpha0 — design-validated (DRC/ERC/SPICE/DFM clean), not yet fabricated or hardware-tested. Treat everything below as pre-production until a first build is verified.

Version 0.1.0-alpha0 — design-validated (DRC/ERC/SPICE/DFM clean), not yet fabricated or hardware-tested. Treat everything below as pre-production until a first build is verified.

An open, self-fabricatable clone of the Electro-Smith Daisy Patch SM — the Eurorack DSP submodule — built around the STM32H750 + 64 MB SDRAM, designed to run stock libDaisy DaisyPatchSM firmware unmodified and to drop into carriers such as kivu12 / eurorack-blocks.

Teresina-Rack: common questions

What microcontroller does the Teresina-Rack use?

The Teresina-Rack is built around the STM32H750IBK6, from the STM32 family.

How big is the Teresina-Rack PCB?

The Teresina-Rack measures 68 × 40 mm, has 12 copper layers and is 1.6 mm thick.

How many components are on the Teresina-Rack?

209 components, from 54 distinct parts. The full bill of materials is listed on this page.

Where can I download the Teresina-Rack design files?

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

Can I use the Teresina-Rack design in my own project?

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

Can I test firmware for the Teresina-Rack 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.
