BOT120 PICAXE-20X2 MICROBOT
The Microbric Connector
The Microbot is delivered as a pre-assembled panel containing the
electronic modules as well a set of self-assembly mechanical parts.
A unique aspect of the Microbot is that all assembly of the main parts
can be completed without requiring a soldering iron or other tools apart
from an Allen key. All parts of the Microbot starter pack either bolt or
clip together so can be quickly and easily connected, rearranged, or
removed as required.
The circuit boards are connected to each other using a patented plastic
‘microbric’. The bric has two purposes, firstly it physically holds the
modules together and secondly it provides electrical connection between
the modules.
Each bric has three holes into which nuts should be inserted to form a
complete bric assembly
Each bric has four locating posts which mount with corresponding holes
in the circuit board modules; two posts go into one board and two into
the other.
Note that the posts only
allow the bric to be
connected in one way.
When correctly oriented
the connecting bric will fit
flush to the circuit board.
If incorrectly fitted the
connecting bric will be
angled to the circuit
board; in this case remove
the connecting bric, rotate
it through 180 degrees and then refit.
When aligned correctly, bolts are then used to clamp the two modules
together and to form electrical contact from one board to the other. Note
that the connection points on the modules are colour coded – the
contacts with the red marking must always connect together.
Always switch the Microbot power off when connecting or
disconnectiong modules. This will prevent accidentally short
circuits if the metal allen key accidentally knocks against two
contacts at the same time.
