SG923-0004

SG923-0004 Kraken Eval Board Overview Features SG923-0004 Kraken Eval Board provides an easy way for customers to evaluate and develop applications with Kraken Wi-Fi modules. The eval board provides power to the module and brings communications interfaces to standard connectors. • Variety of Standard Communications Interfaces - 10/100Base-T (RJ45) - 3 UART ports (2 DB9) - 2 USB ports – Type A host, Mini-B Device - 1 SPI port (Header) • GPIO and Peripherals - I2S Digital Audio interface (Header) - 8-bit camera interface (Header) - Timer I/O (Header • On board regulator accepts 4-12V (5V optimal) Most signals can also be used as generalpurpose IO, and are available at standard 0.1” pitch headers.
