We are proud to introduce the AISLER Lovely Library, a carefully curated collection of symbols and footprints for KiCad. It is designed to simplify your hardware development workflow, reduce ordering errors and support high-quality European manufacturing.
Whether you’re working on a prototype or launching a production run, the Lovely Library makes selecting components from Würth Elektronik and Diotec Semiconductor easier than ever, complete with part numbers, datasheets, footprints and schematic symbols.
And the best part? Using parts from this library can unlock exclusive discounts on orders when uploading your project to aisler.net.
Why another KiCad library?
While KiCad offers an excellent open-source platform for PCB design, many of the default components in its standard library lack orderable part numbers (MPNs) or key specifications. This often leads to:
- Ambiguities during BOM creation
- Delays or manual intervention in PCB assembly
- Substitutions with non-transparent or lower-quality components
- Frustration for developers and support teams alike
AISLERs Lovely Library directly addresses these issues by offering a set of highly detailed, ready-to-use components aligned with KiCad’s structure and licensing model.
Built with Europe in mind
Western component manufacturers are increasingly replaced by Asian manufacturers in the BOM as tools like EasyEDA become more popular. We want to counteract this trend by offering a high-quality, well-documented library.
What’s inside the Lovely Library?
Every part in the Lovely Library includes:
- A fully specified Manufacturer Part Number (MPN)
- A correct and clean symbol and footprint
- Links to the datasheet
- Metadata that aligns with AISLER’s PCBA process
- Compatibility with KiCad’s design flow and file structure
In short: these are components you can search, select and order with confidence.
How to install the Lovely Library
The simplest way to install AISLER’s Lovely Library is by using the Plugin and Content Manager (PCM).
- Download the aisler-lovely-library.zip from the releases page.
- In KiCad, open the PCM in the main overview Window.
- Install the library by selecting the
.zipfile trough “Install from File”. - You’re Done! Note that the schematic libraries will have a
PCM_prefix.
Better Documentation = Smoother Assembly
One of the key reasons we built this library was to streamline the development process and reduce the communication overhead between developers and manufacturers.
Because all parts in the Lovely Library are fully documented and manufacturer-specific, it becomes much easier to:
- Generate consistent and error-free BOMs
- Avoid last-minute part substitutions
- Communicate requirements clearly to assemblers
- Reduce delays in ordering or support
It’s not just about engineering precision. It’s also about saving time and avoiding headaches.
Discounts for using library parts
When you use parts from the Lovely Library in your KiCad project and upload it to aisler.net, you may be eligible for exclusive discounts on:
- PCB production
- Component sourcing
- Full PCB assembly (PCBA)
This is our way of saying thank you for choosing high-quality components and helping us simplify the manufacturing workflow for everyone involved.
