General Description
The Ezurio 60 Series SOM (part number 453-00003 and 453-00004) wireless bridge module is a wireless communications subsystem that may be integrated into a variety of host devices via many available electronic and logical interfaces. The SOM provides complete enterprise-class Wi-Fi connectivity with an integrated TCP/IP stack. It also provides full support for 2x2 MIMO 802.11 a/b/g/n/ac WLAN plus Bluetooth 5.1 dual mode dual-mode air standards with a fully integrated security supplicant providing WPA/WPA2/WPA3 authentication, data encryption, and BT protocol stacks.
The 60-SOM has a wide variety of interfaces including RMII, RGMII, serial UART, Hi-Speed USB, SPI, SDIO, TTL RGB, PCM, and I2C. The wireless bridge may be configured, monitored, and managed via a Command Line Interface (CLI) over an available dedicated console port, via a web interface over a wireless or Ethernet interface, or via a remote SDK interface over wireless or Ethernet.
The 60-SOM incorporates the Ezurio 60-SIPT Wi-Fi SiP module which uses Marvell 88W8997/88PG823. The product also features the ARM® Cortex®-A5 processor running at 536 MHz and an MCP memory with 1 Gb or 2 Gb 32-bit LPDDR1 or LPDDR2 memory, and 2 Gb or 4 Gb 8-bit SLC NAND flash storage. Several GPIO lines are available for data acquisition and similar applications. A software developer’s kit (SDK) with Application Programming Interfaces (API) and software tools are available for the development of custom software applications on the device.
