We are in the process of creating a Nanode specific library that defaults to pin 8, so this change will not be needed in the future. | We are in the process of creating a Nanode specific library that defaults to pin 8, so this change will not be needed in the future. | ||
'''How do I connect External Power to my Nanode?''' | |||
There are at least 3 ways to power the Nanode | |||
1. With a 5V FTDI cable or adaptor | |||
2. With a standard USB lead | |||
3. With an external dc power supply | |||
When using the FTDI cable, put the black wire closest to the USB socket. | |||
With external dc power, use a supply less than 12V, 9V is preferable and connect the positive to the screw terminal closest to the Magjack and the 0V to the next terminal along. | |||
If you want to use 12V or higher, you will need to fit a sutabbly sized heatsink to the tag of the 7805 regulator. The Voltage range for the regulator is 7V to 35V, but in the interests of power efficiency and overheating we do not recommend more than 12V dc. | |||
'''What are the other screw terminal for?''' | |||
Nanodes can be connected to networks in a number of ways, and the screw terminals provides a low cost wired serial bus. Nanodes can be wired together using 4 core telephone cable or network cable, which provides power distribution and communication between Nodes. A separate wiki page describing this feature will be published in the near future. | |||
