User GPIO Signals (J8)
The ReadyBoard 800 provides eight GPIO pins for custom use and the signals are routed to the J8
connector. Ampro has provided sample applications showing how to use the GPIO pins in the
Miscellaneous Source Code Examples subdirectory, under the ReadyBoard 800 Software menu on the
ReadyBoard 800 Doc & SW CD-ROM, (CD-ROM\Software\Misc\GPIO).
For more information about the GPIO pin operation, refer to the datasheet specifications or
Programming Manual for the Super I/O (W83627HF) controller at:

Table 3-21 list the GPIO pin/signals on 10-pins, 2 rows, odd/even (1, 2) with 2 mm pin spacing.

Temperature Monitoring
The Super I/O controller (W83627HF) performs the temperature monitoring function and has inputs
directly from two thermistors on the board. One thermistor is located near the CPU and the other
thermistor is located near the I/O Hub (Southbridge).
NOTE The ReadyBoard 800 requires a heatsink for all processors, but no fan.
Serial Console
The ReadyBoard 800 supports the serial console (or console redirection) feature. The serial console can
be accessed by an ANSI-compatible serial terminal, or the equivalent terminal emulation software
running on another system. This can be very useful when setting up the BIOS on a production line for
systems that are not connected to a keyboard and display.
