Re: Re: Tell me about 1-wire...

[Stuart Poulton <stuart@xxxxxxxxxxxxxx>]

For info, a complete kit of parts as follows

1 - 1wire PCB
1 - Double RJ45 connector
1 - DS18B20 temp sensor
1 - 3 pin header and jumper (to select powered or parasitic)
1 - 3 way screw terminal for remote sensor.

Is £11.00 plus postage, with a discount for 5 or more kits.

I'm happy to discuss pricing for parts indiviually such as PCB's and
RJ45 connectors.

Cheers

Stuart
