Our Raspberry Pi expansion boards and Raspberry Pi accessories are designed and manufactured in the United Kingdom.

Our unique stackable design allows you to stack several expansion boards on your Raspberry Pi without having the mess and inconvenience of having lots of ribbon cables connecting your expansion boards together with your Raspberry Pi.

The popular ADC Pi Analogue to Digital converter easily allows you to measure up to 8 separate voltages on each ADC Pi and they can be stacked giving you up to 32 ADC channels.

If you need to expand your input and output capabilities on your Raspberry Pi the IO Pi gives you 32 IO channels and when stacked you can have up to 128 extra inputs or outputs on your Raspberry Pi.
