Physical Attributes

This page describes the physical attributes modules must conform to to be compatible with the PlugAndProgram Ecosystem.


Housing physical rules:

  • Mounting holes patterns are standardised across the PlugAndProgram range to allow efficient mounting and alignment of multiple modules within the same housing
    • Sized for 3mm screws
    • Spaced vertically at 100mm intervals
    • Spaced horizontally either side of the chassis vertical centre line at -46mm, -5mm,  5mm and 46mm

Module physical rules

Module types are either standard, or edge modules.

Standard modules physical attributes:

  • Width: either full width or half width (100mm or 49mm)
  • Height: always sized in 10mm increments starting from the minimum 18mm
  • Mounting holes: 4 x 3mm on each corner 4mm in from each edge
  • IO Sockets:
    • Full width modules have IO sockets on each side
    • Half width modules have IO sockets on one edge only

Edge modules have either sockets or interaction devices (e.g. a USB socket, toggle switch for power) at right angles to the board on one leading edge.

Edge modules physical attributes:

  • Same as Standard module characteristics except that the leading (exterior edge)edge can extend an additional 5mm in height
  • Mounting holes must align to the same grid pattern as standard modules

Power Distribution socket physical rules

  • All inter-module Power Distribution sockets will utilise RJ style 6P6C DEC/MMJ offset keyed sockets/plugs
    This ensures Power sockets cannot be connected to IO data sockets and vice versa.
  • Can be vertical or right angle depending on the location on the module.
  • Minimum 30uM gold plating on pins

Power Distribution cable physical rules

  • ‘Straight through’ type.  (Pin 1 of one end is always Pin 1 of the other end)
  • ALWAYS coloured RED
  • Minimum 30uM gold plating on pins

IO Data socket physical rules

  • All inter-module IO Sockets will utilise RJ style 6P6C telecommunication sockets
  • Right angle only
  • Mounted on outer sides of modules only
  • Minimum 30uM gold plating

IO Data cables physical rules

  • ‘Straight through’ type.  (Pin 1 of one end is always Pin 1 of the other end)
  • Any colour but NOT Red
  • Minimum 30uM gold plating on jacks
