At the heart of this remarkably compact microcontroller board you’ll find an ingenious bit of integration technology. The combination acts as a versatile plug-in module for lots of applications requiring some form of intelligent control. Thanks to the extensive software that comes with the board and the presence of a PC interface, our drop-in board is excellent for hardware development, too.As many of our readers will be able to confirm, the majority of microcontroller boards look very similar. If the microcontroller used has no program memory, an EPROM is added. Similarly, if there is a lack of RAM, the problem is solved by adding an external RAM device like the 62256. The lot is then complemented with a few logic gates and hey presto we have a basic microcontroller system.
