Radicom Research introduced the RB4000 and RB4000HM Bluetooth modules. The new Radicom modules replace RS232 cable by providing short-range wireless data connectivity. The RB4000 (surface-mount PCB module with on-board antenna), RB4000HM (through-hole module), and RB4000HM-c (built-in U.FL connector) Bluetooth modules are available now. Prices start at US$9.00 for the RB4000 in quantities of 500 pieces.
Microchip Technology introduced the MCP2200 USB-to-UART protocol converter. The MCP2200 is an out-of-the-box solution that makes it easy to add USB connectivity to embedded systems. By connecting the MCP2200 UART interface to any microcontroller UART peripheral, USB connectivity can be added. The MCP2200 includes 8 general-purpose I/O pins that can be controlled by the PC using the Windows-based configuration tool included with the MCP2200. The MCP2200 USB-to-UART protocol converter is available in 20-pin SSOP and SOIC packages for $1.39 each, in 10,000-unit quantities (for both package options). It is also available in a 5 mm x 5 mm QFN package, for $1.50 each, in 10,000-unit quantities.
