DRCB-M1: 802.11 b/g wifi CF module, BCM4318E

DRCB-M1 is an IEEE802.11b/g wifi CF Type-I extended module designed specifically for integration in application-specific devices (ASDs) used in vertical market. Providing the performance, reliability, security, and low power consumption required for business-critical applications, DRCB-M1 has the capability of full size mini-PCI in much smaller CompactFlash® package for small and ergonomic ASDs such as portable data terminals, bar code scanners and portable printers.

Optional WinCE 4.2/5.0 drivers and WiFi security supplicant supports enable ASD manufacturers to provide products that enjoy improved innovation and time to market through trouble-free WiFi integration.

 

Key Features

  • CF Type-I extended form factor is ideal for embedding into new or existing ergonomic application-specific devices.
