These three 802.11 a/b/g/n Wi-Fi module products allow OEMs and System Integrators to enable their M2M communications. Included in these products are the networking stacks with software selectable flexibility to make the OEM project integration fast. OEMs can configure via software any combination of UART, Ethernet, GPIO and 802.11 interfaces. The first one is BB-WLNNA series, which is an embedded module with wide operating temperatures. The compact size of the PCP boards is ideal for smaller machines. The second one is ABDNA-ER-IN5010, a Wi-Fi Dual Band Industrial Bridge/Router. Industrial models feature a rugged metal enclosure with panel mounting (DIN rail optional) and expanded wide operating temperature ranges. The last one is ABDNA-ER-DP551 series, Wi-Fi Dual Band Enterprise Bridge/Router. Enterprise models feature a nylon, desktop enclosure with a narrower operating temperature range.
