This module provides several useful functions that provide information about your Raspberry Pi
Returns a hash reference containing information about
your Raspberry Pi.
the keys are: model, memory, processor, hardware, pinplan,
manufacturer, revision, serial, release
Example for a Raspberry Pi 3
model => 'Raspberry Pi 3'
memory => '1024'
processor => 'BCM2837'
hardware => 'BCM2709'
pinplan => '3'
manufacturer => 'Sony'
revision => '2'
serial => '00000000abcd123'
release => 'Q1 2016'
model : a descriptive string for this RPi model
memory : memory in GB
processor : BCM2837 for RPi 3, BCM2836 for RPi 2,
BCM2835 for all other RPi models
hardware : BCM2709 for RPi 3 and RPi 2. BCM2708
for al other RPi models
pinplan : 1 for the 26 pin GPIO on the original Model
B revision 1.0 board.
2 for the 26 pin GPIO ( and 8 pin PAD 5 ) on the
Model B revision 2.0 and Model A boards.
3 for the 40 pin GPIO on RPi 3, Zero, 2, B+ and
A+ boards.
manufacturer : descriptive string for manufacturer
revision : revision number of this particular board type
serial : serial number of the Raspberry Pi
release : descriptive string for the release date of this
board type and revision
returns 1,2 or 3 - value from 'pinplan'
member of HiPi::RaspberryPi::get_piboard_info();
Returns an array of GPIO pin numbers valid
for this Raspberry Pi. (valid == connected
to the Raspberry Pi GPIO pads.)
For example, the first two array members
for a Model B Revision 1 board are 0 and 1.
The first two array members returned for
a Module B Revision 2 or Model A board are 2 and 3
Returns a hash reference containing the
key => value pairs extracted from /proc/cpuinfo
with an additional key 'GPIO Revision' that
contains the value 1 for the original Model B revision 1.0
board and 2 for all boards since.
The hash is purely informational and should not be used to
determine actions.
For code control, use HiPi::RaspberryPi::get_piboard_info()
Example Returned Hash Key Value Pairs
'GPIO Revision' => '2'
'Processor' => 'ARMv6-compatible processor rev 7 (v6l)'
'BogoMIPS' => '697.95'
'Features' => 'swp half thumb fastmult vfp edsp java tls'
'CPU implementer' => '0x41'
'CPU architecture' => '7'
'CPU variant' => '0x0'
'CPU part' => '0xb76'
'CPU revision' => '7'
'Hardware' => 'BCM2708'
'Revision' => '000f'
'Serial' => '00000000ec4805c2'
A Model A Raspberry Pi will have 2 for the
'GPIO Revision' value.
