We’re also constantly expanding our range and product offering. If you can’t find a specific item in our listings, please reach out to us — we can often source or order it in through our supplier network and add it to our store for you.
Product Variations
With most electronics, manufacturers make design changes that can occur as frequently as each production batch. This means components used, PCB colours, and even pin positions or connections may differ slightly from the images shown.
The images in our listings are for reference only, and all products supplied meet or exceed the stated specifications.
If you have something specific that you require — such as a particular layout, chip version, or pin configuration — please confirm with us prior to ordering.

If you experience a problem
Contact us first before opening a return or case — most issues are resolved quickly with simple troubleshooting.

DIY & Development Products
Many of our electronic modules and components are intended for DIY, maker, and development use. As such, they generally do not include printed instructions in the package. These items are designed for users who are learning, prototyping, or integrating them into custom projects.

We’re always happy to help point you in the right direction and provide example code or configuration snippets. However, please note that we cannot write full programs or custom firmware for individual projects as part of normal support.
Custom Development & Contract Work
We do offer customisation, programming, and hardware development services for larger or ongoing projects under formal contract. These services typically require minimum order quantities and are quoted based on project scope. We don’t provide one-off coding or design services for hobby or single-unit use.
