The Nanode family expands

The original Nanode has proved to be a great success with a growing community of people building many interesting networked devices and this month, Ken Boak, the creator of the Nanode has launched several new additions to the line. The new Nanode RF is essentially an upgrade to the original Nanode 5 with an on board RFM12B wireless transceiver and options for several extras such as a real time clock (RTC), 32KB SRAM and a Micro SD socket.

The second new member of the Nanode family is the WiNode, a low cost wireless node that is available in several different configurations, all using the same PCB with just the installed components differentiating between them. As with the Nanode and Nanode RF, the WiNode can be fitted with the standard Arduino headers for compatibility with Arduino shields as well as the RTC (SOIC or DIP), 32KB SRAM and Micro SD options as with the Nanode RF. The WiNode also features four 16V tolerant analogue inputs and when fitted with a dual H-bridge driver chip it can provide 2A digital outputs for driving relays or motors (although you can’t use the SRAM/SD if the H-bridge is used). Due to a nifty bit of design the WiNode can also be built for use as a shield for the original Nanode to add RFM12B wireless capability and more. Prices are very good, with WiNode kits starting at £17.50 (or £15 if you buy a pair) for the basic stand alone wireless node or only £10 if you want to use one to expand an existing Nanode 5. The Nanode RF kits start at £30 and for the first time a fully assembled unit with all the options is available for £40.

Pictured  above is my first WiNode build, decked out with the SRAM and SOIC RTC options. I’ve fitted all the optional bits on this one, headers, screw terminals and even the socket for the H-bridge driver as I will keep this one aside for experimentation and prototyping, subsequent builds will just include whatever is required for the particular use. That’s the Nanode RF on the left.

As with the original Nanode, both the Nanode RF and WiNode are supplied as a kit for you to build yourself and anyone with basic soldering skills should find it very straightforward. Ian Chilton has already created a very comprehensive guide to building the Nanode RF which is available here and I suspect a WiNode version won’t be far behind (update: WiNode build guide is now almost complete).

Ken says he will have an online shop available shortly but for now you can order by sending a Paypal payment, for further details and prices of the various options see this blog post.
