JeeNodes...couple a low-cost radio to the [Really Bare Bones Board - "one of the smallest and lowest-cost Arduino-compatible boards"], enabling wireless communication. For many people who wish to just send a few bytes from a sensor to a receiver, the available wireless options, such as XBee, are expensive overkill. So we think this little board fills an useful niche. Radios are available in 433 MHz & 915 MHz in the US... Jean-Claude's other big idea was organizing the microcontroller pins into "ports", for easy intergration with sensors and the like. Each JeeNode has 4 identical "ports" for attaching analog and digital I/O logic, I2C devices, and more. Jean-Claude has written a Ports library that makes it simple to interface to these ports. Basically a small Arduino board combined with a two-way radio selling for $22.50 in kit form. Good if you want to build cheap data collection sensors. (Same vendor also sells a $13 Arduino kit without the radio. The "Really Bare Bones Board" mentioned above.) It uses an off-the-shelf radio module ($7 FSK transceiver module): http://www.sparkfun.com/products/9582 http://jeelabs.com/products/rfm12b-board The developer's site: http://jeelabs.org/2011/05/01/meet-the-jeenode-v6/ http://jeelabs.com/products/jeenode A review: http://sharpk60.blogspot.com/2012/06/jeenode-review.html I've been interested in doing some home automation projects and was looking for a good solution for smart wireless nodes. I looked into the typical XBee plus Arduino solution that lots of people used but I want to have many nodes and at $40-50 per node XBees were too expensive. Then I found JeeNodes which can be summarized as inexpensive Arduinos with 2-way radios. I purchased a set of 3 JeeNodes plus a USB-BUB from Modern Device. The USB-BUB is a little USB adapter used to program a JeeNode. [...] I really, really like JeeNodes. The software APIs are easy to use and intuitive. Soldering them was easy. The PCBs are well thought-out. -Tom _______________________________________________ Hardwarehacking mailing list [email protected] http://lists.blu.org/mailman/listinfo/hardwarehacking
