Dmx eth dimmer: common questions

What microcontroller does the Dmx eth dimmer use?

The Dmx eth dimmer is built around the PIC16F877A, from the PIC family.

How big is the Dmx eth dimmer PCB?

The Dmx eth dimmer measures 148 × 156 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Dmx eth dimmer?

109 components, from 34 distinct parts. The full bill of materials is listed on this page.

Where can I download the Dmx eth dimmer design files?

From the CarnivalBen/dmx-eth-dimmer repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Dmx eth dimmer design in my own project?

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

Can I test firmware for the Dmx eth dimmer without the hardware?

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