Electronics Components
We stock a huge range of components and offer same day shipping before 2pm and free technical support. Our catalogue contains discrete components suitable for any sort of project you can imagine - from audio projects like car stereos to GPS projects to ensure you don't take the wrong 'shortcut'. Our components category is ideal for a more experienced engineer looking to create custom boards for hobby electronics and commercial purposes. Design a PCB layout just the way you want rather than relying on pre-made breakout boards.
Support
If you're having problems with any of our components or require assistance with selection of suitable items don't hesitate to contact us. Proto-Pic have a team experienced in programming, electronics and STEM projects that offer free technical support.
