A member of the Port Area Robotics Society has come up with a great but 
simple PC board using a 68HC11. I ran the prototypes for him and recently 
he has had them made by a commercial board house. They are great and very 
low cost. Here are the salient features:

The BOTBoard is the only single chip microcomputer board specifically

designed for robotics applications.  The BOTBoard uses the popular

68HC11 microcontroller, and is easily programmed from your PC.

Engineered to be small, the BOTBoard is also powerful and flexible.

 

Each BOTBoard contains a 2" X 2" processor area and a 1" X 2"

proto-typing area. The proto-typing area allows additional circuitry or

connectors that may be needed.

 

Special BOTBoard Features:

 

.    Four R/C Servo Ports.

.    Reset Switch and low voltage circuitry.

.    Auto start jumper.

.    1" X 2" proto-typing area, with power bus strips.

.    Easy to use Networking Port (SPI). With Master/Slave selection.

.    Powered RS232 Port connector for serial communication.

.    Pull up resistors on IRQ and XIRQ.

.    All I/O pins on .100 grid headers.

.    Single sided circuit board design.

.    Uses either the MC68HC11 or MC68HC811 .

.    Mounting holes that can be used for stacking.

.    Power supply connector.

 

 

Features of the 68HC11:

 

.    Low power, less than 20ma.

.    256 RAM and 512 EEPROM memory with 68HC11, More with 68HC811.

.    Eight A/D converter.

.    RS-232 and SPI serial Ports.

.    Real time interrupt and COP circuits.

.    Auto start EEPROM code.

.    With 36 I/O pins.

.    Timer subsystem with three input captures.

.    Five output compares and input accumulator.

.    Boot loader program in ROM.

 

 

The BOTBoard is a bare circuit board that was designed to give the most

amount of flexibility for the least cost.  Each board costs only $5.95

in singles or three BOTBoards for $15. Following the simple

instructions, you can assemble the BOTBoard in less than a half hour,

with a total cost of the BOTBoard and parts being about $20.

 

With each order the BOTBoard comes with detailed parts list, ordering

information, schematics, building instructions, and application guide.

 

BOTBoard  =  $5.95  each.

BOTBoard  =  $5.00  each for three.

Shipping   =  $1.25 plus .25 for each board.

        If you want to get an idea of his board, I wrote an article for 
Nuts And Volts magazine demonstrating the toner transfer system and my 
CNC machine. The differnce is his new design contains a proto area and is 
2X3 inches. The proto area can be cut off. 
        If you're into 68HC11 stuff you will find this a great buy!
