The BOT-Board

 

 

The BOT-Board is the only single chip microcomputer board specifically

designed for robotics applications.  The BOT-Board uses the popular

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

Engineered to be small, the BOT-Board is also powerful and flexible.

 

Each BOT-Board 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 BOT-Board 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 BOT-Board 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 BOT-Boards for $15. Following the simple

instructions, you can assemble the BOT-Board in less than a half hour,

with a total cost of the BOT-Board and parts being about $20.

 

With each order the BOT-Board comes with parts list and ordering

information, schematics, building instructions, and operating guide.

 

BOT-Board  =  $5.95  each.

BOT-Board  =  $5.00  each for three.

Shipping   =  $1.25 plus .25 for each board.
