The 18M2 Motherboard is the controlling heart of an 18-pin PICAXE system to which other input and output interfaces connect.
The 18M2 Motherboard is the main board to which other create input / output modules connect.
The motherboard contains a PICAXE-18M2 microcontroller, a 3.5mm jack socket download interface for loading programs into the 18M2 plus connections for a 4.5V battery power supply and 13 microbric connection points for other create modules. Programs are downloaded using the AXE027 USB serial cable. The motherboard has a switch to turn its power on and off and includes a LED to show when the board is powered.
For added short circuit protection in the educational environment each i/o pin also has an inline 220 ohm resistor - that is the reason for the extra two resistor array 'chips' seen on this motherboard!
For a moving 'robot' style motherboard for the create system the BOT120 motherboard kit (based around the PICAXE-20X2 microcontroller) will be of interest.
