Build the and AVR and AT89S5x Family learning boards with I/O interfacing modules.

Both Mainboard Features

• Pin compatible for 40-pin AVR and AT89S5x family Microcontrollers
• Single sided PCB, header for 4 I/O ports, ISP port and RS-232 port
• Built in +5V voltage regulator LM7805 with heatsink
• Built in +5V and +12V (depend on input voltage) with terminal screw connector for further expansion
• Onboard In System Programmer header
• Schematic Included
• Both mainboard is identically appearance with minor change

I/O Modules:

LED Board

• The LED board provides 8-bit dot LED. The board can tie to the main PCB easily with a 10 pin ribbon cable.

Download the complete file here : kit_module_new.zip.

The zip file contains all PCB boards, include schematic for both mainboard.

Download the old version here : kit_module.zip.

The zip file contains all PCB boards, no schematic included, an older version of mainboard.

For the board with no schematic included (figure 3 - 7), you can make it yourself, is easy to figure out the schematic from the PCB board.

If you have any question, suggestion or maybe you find a bug, I'll very grateful if you contact me at : logixguy@yahoo.de
