Low-Cost 8051 Development Board Design [ February 28, 2005 ]

This 8051 development board provides an easy and low-cost way to develop projects based on the 8051 microcontroller, without the need to purchase any other equipment, such as EPROM programmers or emulators. Features and Photos Using The Board For The First Time LED Blink Example, Using AS31 Assembler LED Blink Example, Using SDCC C Compiler Memory Map Schematic and Parts List PC Board Details Construction and Testing Troubleshooting Tips Figure 1: 8051 Development Board, Rev 4, With 16x2 LCD Important Features: PAULMON2 v2.1 Monitor, easy to learn and use. All PAULMON2 source code is available for free download, and may be used without any restrictions, even for copy-and-paste into your own programs. Flash ROM for non-volatile storage of downloaded programs, to allow the board to permanently run the downloaded program, without the PC computer. No EPROM programmer is needed to make the board permanently run your application. The Flash ROM can also be used for data logging. Two serial port connectors w/ on-board mux, allowing easier development of applications which require the serial port 32 I/O Signals, and 8 Bit Bus signals, clearly labeled on the board Large prototype area to add custom circuits   The older versions are still on line: Rev 3 (2001) Rev 2 (1997), and Rev 1 (1992). Parts for these boards are no longer available.
