OOBOT40-II Controller Additional Info

The OOBOT40-II Controller uses the Oricom BOT40-II pcb as a platform, coupled with the OOPic II+ microntroller chip.

For technical details
on the pcb, see here:
BOT40-II Controller.

Configurability. The OOBOT40-II is highly-configurable. The proto area, second MAX232 channel, LEDs, and auxiliary voltage regulator areas can be configured to best suit particular user applications.

OOPic Compatibility. The OOBOT40-II Controller Board is compatible with both old and new versions of the OOPic controller chip, in 40-pin DIP package.

The Oricom BOT40 Controller alone can be purchased by people already having the older version OOPics.

NOTE - there is an error in the OOPic manual regards how much voltage can be applied to the Vref pin, which is chip pin RA3 = I/O line 4. The manual says "up to 14V", but in fact, no more than 5V should be applied - else the chip will be damaged. Indeed, no more than 5V hard-voltage should be applied to ANY pin on the OOPic chip.

OOPic Pinout on OOBOT40-II Board
The figure on the right shows how the physical pins on the OOPic chip correspond to operational functions in the software. This includes which pins correspond to which OOPic I/O lines and groups, as well as which connect to the hardware on the OOBOT40 pcb - such as the program eeprom, MAX232 chip (serial Rc/Tx), and I2C buss header.
