Because of the popularity of the BOTBoard, many people have
asked me to design a controller board for bigger robots.

I finally did.

I wanted to design a board that contained the best features of
many of the popular controller boards and pack them into one
board, the BOTBoard 2.

Features of the BOTBoard 2 Board Design:

- 4" x 5" Inch Board Size	
- 32k SRAM with Battery Backup
- Large Prototyping Area
- Easy to use Expansion Port with
  up to 64 pins I/O.  (Just add latch or buffer)
- 4 Futaba Servo Ports	
- 4 Four pin Analog Ports
- Piezo Speaker for sound
- 10 pin IDC for PortE (analog) with 8 analog inputs
- LED indicator on I/O port
- Memory Protect Jumper
- 10 pin IDC for PortA	
- DIP switch for MOD A/B and Other Functions
- Full SPI Port
- Low Voltage Reset with DS1233
- RS232 Serial Port 
- Uses Motorola MC68HC11 family, 52 pin PLCC
- BOTBoard Compatible Serial Port
- Double Sided, Silk Screened Board


The BOTBoard 2 is a bare printed circuit board that allows you to build
a powerful microcontroller system.   It is designed to be easy to use,
powerful, and flexible.  I wanted to design a controller board so that you
can get the most out of the 68HC11.  The BOTBoard 2 can be built for
about $50 including the price of the PC board.  It is perfect for medium
to large size robot projects.

A draft copy of the BOTBoard 2 manual is located at:

Manual:  BB2_DOC.ZIP

Graphics: BB2_LAY.GIF BB2_SCHM.GIF

The format is for the BOTBoard 2 manual is  MS WORD 6.0.  The manual
contains parts list, schematics, layout, boards functions,
and detailed graphics.

The BOTBoard 2 is only $20 each, or 3 boards for $45.  Add $3 for shipping.
