Business overview

We are first and foremost a team of engineers who love working with the products we sell and coming up with innovative solutions to common problems faced by the enthusiast.

Willow Components were founded after the successful launch of a couple of Raspberry Pi add on boards. The team have run a successful contract design and manufacturing company for over 10 years and discovered that other people liked what we were doing with our expansion boards. We focus very much on the enthusiast and offer technical support on all the products we make as well as those third party items we stock. Our range is increasing on a daily basis and includes the Raspberry Pi credit card sized computers, a selection of Arduino boards as well as Microchip PIC parts. We also have peripheral boards such as GPIO boards, relays, Real time Clocks etc. In addition we carry a range of prototyping equipment and 'get started' kits. We pride ourselves on our commitment to delivering a first class service for first class products. We love to hear from our customers, either with technical questions or ideas for future products. So please, give us a call.


This innovative board lets you connect up to three Raspberry Pi add on boards to any Pi with a 40 way GPIO and work on them at the same time. There is no need to assemble and dis-assemble stacks of boards while de-bugging. It can accommodate two full sized boards and a smaller HAT board.
This great little board allows easy termination of the Arduino Nano board. Just plug in and use a screw driver for the rest. This board is fully assembled, ready to use. We also offer it combined with an assembled Arduino Nano board.
A simple but very effective way to hook up to your Raspberry Pi 40 way GPIO. We decided to go full size with this board to make access via terminal blocks easy. As you can see from the image, if you want to 'stack' the board, you will need an extra connector, which we can supply, or use our FLAT Pi.
