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.
Features:
- 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
- As easy to use as simple SEROUT/SERIN PBASIC instructions
- Power-down mode for conservative enter usage (longer battery life)
- Line-of-sight range of 500 feet (or greater depending on conditions)
Application Ideas:
- Remote Controlled Boe-Bot® robot
- Wireless data acquisition
- Remote sensors and triggers
