About the Supra board

Supra board is an open source RP2040/RP2350 PCB design by jsenzel1, published on GitHub. It is a 2-layer board measuring 49.5 × 106 mm, with 119 components from 48 distinct parts.

Its main chip is the RP2350_60QFN, from the RP2040/RP2350 family. Other key parts include the LD1117S33CTR, PCF8523T, W25Q128JVS and OPA1679. By type, the board carries 46 resistors, 27 capacitors, 18 diodes, 11 connectors, 5 ICs and 5 switches.

From the project

is multimode Eurorack module with 4 different experiments in long term time. you can run up to 2 modes at once. use the 4 way joystick and buttons to interact with the modes on the oled

Supra board: common questions

What microcontroller does the Supra board use?

The Supra board is built around the RP2350_60QFN, from the RP2040/RP2350 family.

How big is the Supra board?

The Supra board measures 49.5 × 106 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Supra board?

119 components, from 48 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Supra board design files?

From the jsenzel1/supra repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Supra board design in my own project?

The repository has no license, so all rights stay with jsenzel1. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Supra board 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.
