Open source Retro Rom Carts and ODEs by Dreamcraft Industries

Dreamcast GD-ROM replacement. WIP! Untested and not in production state!!!

Will use RP2040s and SD Card to emulate the gdrom drive.

RP2350B QFN-80 Minimal Design Example: common questions

What microcontroller does the RP2350B QFN-80 Minimal Design Example use?

The RP2350B QFN-80 Minimal Design Example is built around the TS3L501ERUA, from the RP2040/RP2350 family.

How big is the RP2350B QFN-80 Minimal Design Example PCB?

The RP2350B QFN-80 Minimal Design Example measures 162.2 × 103.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the RP2350B QFN-80 Minimal Design Example?

48 components, from 33 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 RP2350B QFN-80 Minimal Design Example design files?

From the khill25/Dreamdrive 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 RP2350B QFN-80 Minimal Design Example design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the RP2350B QFN-80 Minimal Design Example 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.
