| DEV_PCB_KIT | Complete Kit for the 8051 Development Board, Rev 5 | $68 |
This $68 unassembled kit includes the bare printed circuit board and all the components that solder to it. (materials shown in the photo below are what is included). You do not need to also order the $25 bare board, unless you want to have an extra bare circuit board. The optional 20x2 LCD is not included. This kit also does not include a Serial Cable or a Power Adaptor.
The 8051 development board provides an easy and low-cost way to develop your 8051 based microcontroller projects, without purchasing any other equipment, such as IC programmers or emulators. The kit comes with an 87C52 chip loaded with PAULMON2, which provides a simple menu-based system that enables you to download your own code into the RAM or Flash ROM on the board. When your project is finished, you can set a few bytes to tell PAULMON2 to automatically run your program at start-up, and download it into the Flash ROM chip, so the board will then run your application instead of booting into the PAULMON2 menu system. A jumper is provided, should you need to erase the Flash ROM to make any changes.
The board features 50 I/O lines, in addition to the 8 LEDs, and the 8051's bus lines. A second serial connector is available, with a simple switching circuit, to make it easier to develop applications that need the serial port and must not see the menus from PAULMON2. The bottom section of the board is a pad-per-hole prototype area, where simple circuits can be added.
This complete kit comes with all the components required to build the board, including the 87C52 pre-programmed with the correctly configured version of PAULMON2.
