The Parallax RF modules provide a very easy and low-cost method of sending data between microcontrollers or to a PC from 500 ft+ line-of-sight (depending on conditions). This device can be connected to a PC serial port using a MAX232 line driver. The circuit isn't supported by Parallax, but it's possible to make this connection with a few dollars of parts.
* High-speed data transfer rates (1200 ~ 19.2k Baud depending on controller used)
* SIP header allows for ease of use with breadboards
* Compatible with all BASIC Stamp® modules (including BS1 and Javelin Stamp) and SX chips
