I’m looking for a number of wireless transceivers for a school project. Seven nodes altogether, one central and six outside. The way the project currently looks, the outside nodes don’t need to communicate with each other, just the central node, so I think point2point or point2multipoint will work. The biggest things are, it NEEDS to fit in a 0.1" spacing breadboard, and NEEDS to support at least 100 kilobits/second. Simple is preferable to cheap. ZigBee looks too complicated, so I’ll pass on that one. Any ideas? Thanks.
SFE MiRF V2?

Use Maxstream/Digi 802.15.4 modules without ZigBee. Use their serial port emulation software. You can plug the modules into a PCB or sockets, or plug them into a purchased PCB that has sockets. Available from several including SparkFun. These modules make it very simple. No coding except for your application’s logic.
@ Leon: Interesting. Helpful, but not in the way expected. The nRF24L01 mod would be useful itself, but I’‘d need to get antennae separately, and there aren’‘t many in stock. However, that page mentioned the nRF2401A mod, which I checked out for kicks. Not only are there quite a few in stock (I’‘ll need these pretty soon, actually) but the antenna is built-in (and cheaper than the nRF24L01 + recommended antenna). Plus, SparkFun has its own data shee+ for this one. I forgot to mention that distance wasn’'t much of an issue (maybe 30 feet indoors, tops). And, 100kb/s was a minimum, faster works too. But, now I have three more questions:
-
How reliable is the nRF2401A? The primary reason I said no to ZigBee was because I was advised that there tends to be random packet loss, higher than with other protocols.
-
Exactly how many pins are on this? Even the photos seem to show either 7 or 11. If it’'s 11, is it OK to not connect 8-11?
-
Why exactly is shee+ a forbidden word? My original post triggered the filter and, yes, I spent the time to figure out why.
