BOT40 Blow-Up

The OricomTech BOT40 Controller Board is designed for controlling small mobile robotic devices and for general industrial-control applications. It uses a 40-pin PIC microcontroller, is designed especially for PIC enthusiasts, and presents an alternative to 68HC11-based botboards.

The BOT40 Controller Board is sized to meet mini-sumo specifications. It can be used for a simple bot, but has plenty of expansion capability for growth into a very sophisticated bot - room for multiple-bumper, line-following, fire-fighting, and other sensor circuitry. It is used in our OOBOT40 Robot Control Computer.

Among many features, the board has voltage regulator, RS-232 port, I²C serial EEPROM chip, and up to 29 I/O channels total, including:

3 additional drive circuits for relays, LEDs, & servos - up to 5A

up to 18 digital I/O lines [non-dedicated]

up to 7 A/D channels

prototyping area

can control up to 8 uni-directional motors, 4 bi-directional motors, or 2 stepper motors

Using one of these boards, you can build a powerful control computer for as little as $50.

Typical applications:

small robot controller

general industrial controller

servo controller

motor controller

closed-loop control systems

h-bridge motor controlled mini-sumos

The table at right compares features of the Oricom SBC40-BOT board with the 68HC11-based Handyboard. In general, when using the SBC40-BOT board you get significantly more signal conditioning and output control capability for significantly less cost. Click here for more info on the Handyboard.

Programming

The BOT40 boards include a PIC16F877 or 16F877A, 20-Mhz microcontroller chip pre-programmed with a bootloader in the on-chip eeprom, so that a separate chip programmer is not required to start programming the PIC. However, the PIC can be erased and a separate chip programmer or ICSP can be used, if desired. Check the BOT40 Programming Page for details.

The BOT40 boards can also be ordered without the '877 cpu chip - e-mail us for details: sales@oricomtech.com.

The BOT40 boards are compatible with the following microcontrollers, in 40-pin DIP package:

PIC Compatibility - the boards accommodate the following Microchip controllers:

16C74 / 77 / 774
16F74/ 77/ 874 / 877
18F442 / 452 and other new 18F' series chips

OOPic Compatibility - the OOPic controller and eeprom chips drop straight into the board. Refer to the next page for additional info about interfacing the oopic.

Basic Atom Compatibility - the Basic Atom Interpreter 40-pin DIP chip, P/N B0030, is based upon the PIC 16F877 chip and will plug directly into the board. The two RS-232 channels on the board can be used for Basic Atom programming.
