Diamond Systems Corona

Introduction

The Corona SUMIT-ISM Communications module features a WiFi card in the SUMIT-ISM Type I form factor. The product contains a WiFi LAN card connected via a mini-PCI socket, two 10/100Base-T Ethernet ports, two USB 2.0 ports if supported by the host system, a socket for a 2.5" SATA SSD card, an SDVO to VGA converter, and both a SUMIT-A connector and a PC/104 (ISA) connector for expansion.

The WiFi card is a dual channel/dual antenna mini-PCI IEEE 802.11a/b/g wireless LAN that supports up to 108Mbps transmit and receive rates. Its average power is up to 200mW with peak power up to 600mW.

The on-board dual 10/100Base-T Ethernet ports provide a high speed option for communication with remote hosts.

The SDVO to VGA converter is designed to accept the SDVO output from Diamond's Aurora single board computer and convert it to an analog VGA output.

On the bottom side of the module is a mounting location for an add-on 2.5" SATA solid state flashdisk (SSD). This can be used for data storage before off-loading to a host system either through one of the stackable expansion options or the Ethernet port. Diamond's enclosure-less SSD simplifies integration and reduces size, weight, power and cost.

Corona was designed with outdoor applications in mind. It is ideal for access point applications or a wide range of other embedded computing applications. Extended temperature operation of -40°C to +85°C is tested and guaranteed. The mini-PCI wireless module mounts securely to the carrier through a standoff and screw.

Corona has both SUMIT-A and PC/104 (ISA) stack through expandability. Therefore it can be used in embedded computing systems with legacy PC/104 stacks, as well as new SUMIT based architectures.

SATA Solid-State Disks

The SATA solid-state disks (SSDs) contain a controller, embedded firmware, flash media, and male connector. Using NAND flash memory devices, the SSDs interface with the host SBC allowing data to be seamlessly transferred between the two. The SSDs are designed with a single-chip controller and provide full support for the SATA II high-speed interface standard. They operate at sustained access rates of up to 100 megabytes per second, which is much faster than other solid-state or traditional SATA drives, and implement a static wear-leveling scheme to allow uniform use of all storage blocks, ensuring a significantly increased lifetime of the flash media and optimized disk performance. A SATA power cable and data cable are included with each SSD product.
