4DPi-32/35 Rev2.0 Workaround
Introduction
This document outlines a work around for using the 4DPi-32-II (Rev2.X) and 4DPi-35-II (Rev2.X) with the older
Raspberry Pi A and B versions with a 26-pin Header.
Background
The latest versions of the Raspberry Pi include a 40-pin Pin-header. In the older versions a 26-pin header was used
with an RCA Connector and Audio jack positioned next to the Pin-header. In the latest versions of the 4DPI-32/35,
the 26-pin female header has been replaced with a 40-pin female header to better accommodate the latest
versions of the Raspberry Pi. For this reason, it is no longer possible to physically connect the 4DPi-32 and 4DPi-35
directly onto the older versions of Raspberry Pi.
