The OricomTech OOBOT40-3 Robot Control Computer is designed for controlling small mobile robotic devices and for general industrial-control applications. It uses a 40-pin OOPic microcontroller chip, which is designed especially for robotics applications. The board can be used for a simple bot, but has plenty of expansion capability for growth into a very sophisticated bot - room for bumper, line-following, fire-fighting, and other sensor circuitry. The OOBOT40-3 board will also mount a regular PIC microcontroller chip, in place of the OOPic, for custom programming.

MAX232 chip + additional RS-232 header + compatible with serial LCDs dual 2-Amp h-bridge chip + large heatsink (not shown above) 3.5-mm motor terminal block (for easy hookup) + recirculation diodes + heavy-duty EMI filtering Size: 4.1"x3.0" main RS-232 connector . 40-pin OOPic chip . . .

OOBOT40-3 Special Features motor current-limiting: connected to the two h-bridge channels, the board has current-sense and limiter circuitry, which limits max motor currents. Useful to limit current in small motors and short-circuit current in stalled motors, without over-stressing the h-bridge chip. RS-232 daisy-chain: the primary transmit-receive channel on the MAX232 chip is used by the OOPic internal UART, while the 2nd transmit-receive channel can be used for either general serial connections [eg, to external serial LCD], or to connect OOBOT40-3 boards in a daisy-chain arrangement for connection to a host computer. Servo header (HDR2): separate halves of middle-buss configurable for +5v to drive external devices, or external servo power input. I²C headers: the board has both PRG and I²C headers, and both can be configured for connecting general I²C devices used with the oI2C object. Typical Applications small robot controller general industrial controller servo controller motor controller h-bridge motor controlled sumo OOBOT40-3 Advantage - For just a few dollars more than a basic OOPic board, you also get a dual-channel motor controller. Would cost $30 - $60 more for separate boards, and take up much more space. The OOBOT40-3 is only 1.6" longer than the OOPic-R, and has the motor controller built-in, so no extra cabling is required.

NOTE - the OOBOT40 Controller Boards are backward compatible with all 40-pin OOPic chips, and can be purchased without the OOPic, for those having the chip already. See here.
