Adding the optional PIN headers to the Pi-DAC+
The Pi-DAC+ will work without adding any additional pin headers. A 30 way pin header is for those
who may want to access the B+’s GPIO and add things like rotary encoders, LCD screens or IR
sensors.
It is recommended that the 30 way RIGHT ANGLED pin header should be added to the underside of
the Pi-DAC+. This allows usage of the Pi-AMP+ whilst retaining access to the Pi’s GPIO signals.
For those with very early Pi-DAC+, the 2x5 way straight pin header is designed for pins 1-10 of the
40way. These should be soldered to the TOP of the Pi-DAC+ and allow the Pi-AMP+ to power the
Raspberry Pi/Pi-DAC+ in parallel.

The RIGHT ANGLED Pin headers are designed for pins 11-40 of the 40way. These should be
soldered UNDERNEATH the Pi-DAC+
