About the Rdi dbt03 multiplexer PCB

Rdi dbt03 multiplexer is an open source Raspberry Pi PCB design by bildschirmtext, published on GitHub under the MIT license. It is a 2-layer board measuring 138.5 × 64.9 mm, with 9 components from 4 distinct parts.

Its main chip is the Raspberry_Pi_2_3, from the Raspberry Pi family. Other key parts include the 74LS138. By type, the board carries 4 connectors, 2 ICs and 2 resistors.

From the project

Hardware, Software and Firmware for a Raspberry Pi to DBT-03 adapter

There is now a possibility to directly patch a Bookworm Raspbian image.

Run ./patchimage.sh as root. It only works on uncompressed images. You can then dd` that image onto your SD-card or use the Raspberry Pi Imager. The later also allows you to set settings. The image will reboot multiple times.

The boot partition can also hold a btxconfig.txt` file where you can configure the host to connect to.

Rdi dbt03 multiplexer: common questions

What microcontroller does the Rdi dbt03 multiplexer use?

The Rdi dbt03 multiplexer is built around the Raspberry_Pi_2_3, from the Raspberry Pi family.

How big is the Rdi dbt03 multiplexer PCB?

The Rdi dbt03 multiplexer measures 138.5 × 64.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Rdi dbt03 multiplexer?

9 components, from 4 distinct parts. The full bill of materials is listed on this page.

Where can I download the Rdi dbt03 multiplexer design files?

From the bildschirmtext/rpi-dbt03 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Rdi dbt03 multiplexer design in my own project?

Yes, under the terms of its MIT license, which bildschirmtext chose for the repository.

Can I test firmware for the Rdi dbt03 multiplexer without the hardware?

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