Stackable Raspberry Pi compatible Expansion Boards

Our stackable design allows you to connect several expansion boards on your Raspberry Pi.

The popular ADC Pi Plus Analogue to Digital converter allows you to measure up to 8 separate voltages from sensors and other inputs. Stack up to 4 ADC Pi Plus boards together to give you up to 32 ADC channels.

Need to expand the input and output capabilities on your Raspberry Pi? The Expander Pi gives you 16 IO channels, 8 ADC inputs, 2 DAC outputs and a real-time clock.
