0x32: 3xIDC connector Pi Top Module

 

.

Background

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 interfacing of external hardware using up to three 40-way IDC cable connected to the 34-way Pi Top hub header.

Function

This design breaks out the conventional 40-way RPi GPIO from the 34-way Pi Top hub connector and allows external hardware to be easily interfaced to the Pi Top using standard 40-way IDC cable.

Bill of materials

3 pcs. 40-way IDC connector (for connecting external boards with polarised IDC cables – recommended option)

1 pcs. 2×17, 90 degree, 2.00 mm pitch, male header

3 pcs. 3-way terminal block, 5.08 mm pitch

 

Estimated cost

Three IDC connectors,  a male angled header, and a 9-way terminal block should not cost more than EUR 8,-.
