Si4438 small wireless module and development board
Features
|
The 4438-490-PDK development kit provides all the necessary tools for evaluating Si4438 IC for smart meter design at 490MHz. The tool kit includes two motherboards based on the C8051F930 MCU, two RF pico-boards optimized for the 425-525MHz band, and two antennas, making it easy to build wireless connections.
Silicon Labs' GUI-based wireless development kit (WDS) software can automatically generate sample code, enabling developers to quickly and intuitively create and develop reliable, cost-effective wireless applications.
