hi,,, this my custom designed picaxe master project controller board, this has a max ability to control up to 16 servo, 16 general purpose inputs and outputs. the required channel can be switched on using the on board dip switch, this is a extra security feature, as in the picture the board has an led indicator indicating power on and standby condition. this also has an on board programming port which is a regular picaxe feature. the board has dual inputs (i,e) it can be powered with a 5v power supply or a 12 volt SMPS wall adapter, the board has several 5v, 12v tapping rails that allows the user for powering various shields attached to it. for a sample i' ve made a L293D motor driver shield the directly plugs into the board like "RAM'S" IN A COMPUTER MOTHER BOARD. the power rails can be given any voltage depending on the voltage needed by the output components. this is a well designed compact package that is bet suited for budding DIY robot builders
