-The Cerebot Nano has five 6-pin header connectors for connecting to general-purpose, off-board digital I/O or to specific ATmega168 features like analog-to-digital converters or pulse-width modulators. Each 6-pin connector provides four signals, power, and ground. These connectors are specifically designed to work with the Digilent Pmod line of peripheral boards, but can be used to connect to virtually any off-board I/O device.+The Cerebot Nano has five 6-pin header ports for connecting to general-purpose, off-board digital I/O or to specific ATmega168 features like analog-to-digital converters or pulse-width modulators.

-See Table 1 for more information on connecting peripheral modules and other devices to the Cerebot Nano. Table 1 shows the connectors with their designed base function and a map to the ATmega168 I/O ports.

 Each of these connectors provides a VCC and a ground pin.  A power supply providing between 2.7 and 5.5 volts can be connected to the VCC pin on any one of these connectors. Each of these connectors provides a VCC and a ground pin.  A power supply providing between 2.7 and 5.5 volts can be connected to the VCC pin on any one of these connectors.
  
-When the Cerebot Nano is plugged into another Digilent microcontroller or FPGA board, that board can power the Cerebot Nano through the Pmod connector.  The host board should be jumpered to provide 3.3V on the VCC pin of the Pmod connector being used.  The Cerebot Nano will then be powered by the host board’s power supply, and will in turn provide power from the host board to any peripheral boards connected to the Cerebot Nano’s other Pmod connectors.+When the Cerebot Nano is plugged into another Digilent microcontroller or FPGA board, that board can power the Cerebot Nano through the Pmod port.  The host board should be jumpered to provide 3.3V on the VCC pin of the Pmod port being used.  The Cerebot Nano will then be powered by the host board’s power supply, and will in turn provide power from the host board to any peripheral boards connected to the Cerebot Nano’s other Pmod connectors.
