0x33: perfboard Pi Top Module




The Pi Top is becoming a popular platform for software development using the Raspberry Pi singleboard computer. However, interfacing hardware to the Pi Top can be challenging, since the hub does not conform with the RPi GPIO header. This module enables easy perfboard prototyping and connections to the 34-way Pi Top hub.


This design breaks out the conventional 40-way RPi GPIO from the 34-way Pi Top hub connector and allows small ad-hoc prototyping circuits to be easily interfaced to the Pi Top. The board is ideal for testing ideas, before moving on to designing a full-blown dedicated circuit board.
