Rabbit Semiconductor’s Wireless Control Application Kit provides a development reference to interface a low-cost, license-free 900 MHz or 2.4 GHz wireless data modules from Maxstream to a Rabbit-based embedded system. The Wireless Control Application Kit contains a low power Rabbit LP3500 single board computer SBC, and two MaxStream RF Modules. The SBC has 26 I/O, eight analog input, six serial ports and a power save mode that draws <100 µA. The 900 MHz Application Kit features the OEM XCite RF modem from Maxstream, intended for US applications. The 2.4 GHz Application Kit features the extended range XStream RF modem for projects worldwide. Both modems are functional replacements to a serial cable, so developers can do away with cumbersome hard wired solutions. Sample programs and libraries are designed for quick out-of-the box development. A Modbus master PC application allows the user to control the SBC as a Modbus wireless slave device.
