From the project
A lighting controller, control surface with 5 faders and 2 encoders, a USB DMX interface, an ARTNET node, and a standalone DMX generator. The Core-Micro system consists or 4 modules; the logic processor, the control surface, the DMX interface, and the redundant USB-C power supply
A lighting controller, control surface with 5 faders and 2 encoders, a USB DMX interface, an ARTNET node, and a standalone DMX generator. The Core-Micro system consists or 4 modules; the logic processor, the control surface, the DMX interface, and the redundant USB-C power supply. These modules are designed in a way that allows them to be iterated on separetly and allow for a limitless amount of configuration. How do you use Core-Micro? It depends on how YOU need to use it. Core-Micro can be used as a midi controller for On-PC lighting softwares, it can be used in a standalone mode where it…

Core micro surface: common questions
What microcontroller does the Core micro surface use?
The Core micro surface is built around the RP2040, from the RP2040/RP2350 family.
How big is the Core micro surface PCB?
The Core micro surface measures 230 × 153 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Core micro surface?
140 components, from 23 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 Core micro surface design files?
From the zeerolux/core-micro 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 Core micro surface design in my own project?
The repository has no license, so all rights stay with zeerolux. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Core micro surface 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.
