About the Baseboard 2slots PCB

Baseboard 2slots is an open source RP2040/RP2350 PCB design by OpenLightingProject, published on GitHub under the Apache-2.0 license. It is a 2-layer board measuring 216.8 × 60 mm, with 38 components from 18 distinct parts.

Its main chip is the Pico, from the RP2040/RP2350 family. Other key parts include the NRF24L01_Breakout and W5500_Mini_TH. By type, the board carries 18 capacitors, 14 connectors, 3 ICs, 2 resistors and 1 diode.

From the project

RP2040-based USB DMX dongle with integrated web server

The rp2040-dmxsun is a multi-purpose DMX-512-A toolbox to control stage lighting systems. It's most common use-case is to transmit the DMX data generated on a PC, Raspberry Pi or similar in a format that the lighting fixtures on stage can understand. In the most simple case, it's an USB-DMX interface.

DMX-512-A works in networks called universes and each universe can contain up to 512 slots of data. dmxsun can transmit up to 16 universes, meaning you can control 8192 slots of DMX data at the same time.

Baseboard 2slots: common questions

What microcontroller does the Baseboard 2slots use?

The Baseboard 2slots is built around the Pico, from the RP2040/RP2350 family.

How big is the Baseboard 2slots PCB?

The Baseboard 2slots measures 216.8 × 60 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Baseboard 2slots?

38 components, from 18 distinct parts. The full bill of materials is listed on this page.

Where can I download the Baseboard 2slots design files?

From the OpenLightingProject/rp2040-dmxsun repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Baseboard 2slots design in my own project?

Yes, under the terms of its Apache-2.0 license, which OpenLightingProject chose for the repository.

Can I test firmware for the Baseboard 2slots 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.
