DIO51 Single Board Computer - $99

DIO51 Enclosure - $20

The Industrologic DIO51 is an Atmel AT89C51RC2 microcontroller based single board computer designed to be an easy to use and versatile development platform for Flash memory based microcontrollers. Its convenient screw terminal block connections, along with its optional ABS plastic enclosure, allow it to be used as a general purpose I/O controller assembly as well.

The DIO51 includes a simple monitor program written specially for the hardware on the DIO51, preprogrammed into the microcontroller. This program allows the DIO51 to be immediately used as a simple RS-232 slave I/O controller, or for testing external devices during development.

The AT89C51RC2 microcontroller chip can be reprogrammed using any number of software development tools available for similar Atmel microcontrollers.

The DIO51 is also compatible with the Philips/NXP P89C51Rx2 and P89V51Rx2 series of microcontrollers, which can be programmed with software development tools available for these microcontrollers.

• Based on the Atmel AT89C51RC2 microcontroller operating at 22.1184 MHZ
• Serial RS-232 port with true RS-232 drivers and DB9 connector
• Convenient screw terminal block connections for all I/O and power connections
• On-board +5 power supply capable of powering external circuits
