=== Q: My Nanode can't access the ENC28J60 and comes up ENC28J60 Version 0 === | |||

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. | ||

A good option if you have a server is to set up a screen session to run Irssi so that you don't miss anything. [http://quadpoint.org/articles/irssi] is a good guide to using screen and Irssi. | A good option if you have a server is to set up a screen session to run Irssi so that you don't miss anything.

=== How do I connect External Power to my Nanode? === | |||
There are at least 3 ways to power the Nanode | There are at least 3 ways to power the Nanode | ||

If you want to use 12V or higher, you will need to fit a suitably sized TO220 heatsink (say 50mm x 25mm)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. | If you want to use 12V or higher, you will need to fit a suitably sized TO220 heatsink (say 50mm x 25mm)to the tag of the 7805 regulator.

=== 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. | Nanodes can be connected to networks in a number of ways, and the screw terminals provides a low cost wired serial bus.
