what is the diff between the

433 MHz RF Transceiver
(#27982)
$39.99

and xbee. especially the higher cost of the 433 MHz RF Transceiver ? what are its advantages,

Franklin

Which xbee? What differences are you interested in specifically? The xbee ($22) requires a adapter to connect to most micros ($34) the transceiver does not. Xbees are somewhat smart and can do simple tasks on their own the transceiver can't.

The XBee is a more refined device. Go with XBee Pro for slightly more $$ and a longer range. The adapter ( https://solarbotics.com/product/50828/) is about $10 and will allow easy connection to a micro.

Also, if its for a sellable project, the XBee has the appropriate government approvals already. As mentioned, the XBee can do some things without a micro.

I think this $4 board would work fine with lots of microcontrollers. If the uC is a 5V variety, you'll want to use a level sifter on the data lines.

I think the $35 board make it easier to configure the XBee with a PC. Nope, I just checked. It's just an expensive (but I'm sure high quality) way to use a XBee with a 5V microcontroller. There are lots of less expensive ways to connect a XBee to a 5V uC.

This is my cue to mention the inexpensive Nordic nRF24L01+ transceivers.

They cost a little more than a dollar (when you purchase several at once) provide two-way communication.

They're not as easy to use as the XBee and require more I/O pins (five or six). There's code available to use the nRF24L01+ transceivers for both the Propeller and the Basic Stamp.

I have more information about this transceivers in post #1 of my index (see signature).

The nRF24L01+ has to be powered with 3.3V but the I/O pins are 5V tolerate.
