Introducing a minimalist style Printed Circuit Board LoRA trained on a dataset of 2-color, monochrome images of circuit boards and traces. This model has no electronic components, only the bare-boards! I tried using other LoRAs for circuit board traces, but kept getting halation, blurry lines, faces and other unwanted stuff in the output. Since I mainly make animations with Deforum, I really need consistent results and prompt engineering just wasn't specific enough for this style.
This LoRA works great with anything technology-themed and fills a gap in every base model I've ever used. I regularly have technology themes in my work and I've tried to get circuit board and traces from every major base model on civit.ai without any luck. Even with all prompt engineering tricks I've learned to date, I still always get random chips, VRMs, capacitors and other components popping up and 2D or Vector-image styles are simply Unobtanium. Prompting alone is not enough, in my experience.
If you like clean, high-contrast designs with solid colors and no glowing lines, bloom, halation, and OMG anything with no shadows, raytracing, depth, or other 3D effect, you should find this LoRA useful.
To use, put the file in your Lora directory and paste this text in your prompt:
<lora:PCBv2:0.5>
Adjust "0.5" between 0.1-1 to suit your needs. This will vary, depending on many factors. This model works well at any strength and worked well with every SD 1.5 model I tried.
If you find this model useful, please consider buying me a coffee:
More non-portrait LoRAs to come!
Description
Version 1.0 was quite good, but didn't have a large enough dataset to handle any need, so v2.0 was trained on 10x as many images, all monochrome images of circuit boards. These are not to be confused with CAD PCB schematic/diagrams, which include text labels, multiple colors and cross-hatched objects, since they must discriminate multiple levels of traces on a board. I have a different LoRA for those.
