Power
The rPi-28D can be powered from either 5V DC or 12V DC although the 12V is actually
tolerant of any voltage in the range of 9V to 24V. The connected Raspberry Pi is powered
from the same power source. You can power the rPi-28D off the Raspberry Pi’s power input
if absolutely necessary or desired.
If running the rPi-28D from 5V then connect the power to the 0V and 5V terminals of CN5
the 3 pin PWR terminal block. A 2A fuse is recommended in series.
If running off 12V (see range above) then connect the power to the 0V and 12V terminals of
CN5. A 1A fuse is recommended in series.
The 3 pixel outputs can be powered from the same or different voltage power supplies. The
pluggable pixel connectors are rated at 7.5A so a fuse of no higher than 7.5A should be in
series with the power input.
Connecting 12V to the 5V power input will damage components on the pcb and may
damage the Raspberry Pi. Connecting 5V to the 12V input will cause the board to not
work due to insufficient voltage.
