WF200
HF-Transceiver, 2.412GHz-2.484GHz, 72.2MB/s, 16.4dBm Ausgang, -91.7dBm Eingang, 1.8V-3.3V, QFN-32
Der WF200 ist der perfekte WLAN-Transceiver für Ihre sicheren IoT-WLAN-Anforderungen. Der WLAN-Transceiver enthält ein 2,4-GHz-802.11b / g / n-Funkchip (MAC- und PHY-Schicht), das für niedrige Stromaufnahme und optimale HF-Leistung in überfüllten HF-Umgebungen optimiert ist. Das Gerät unterstützt sowohl Linux-basierte Hosts als auch RTOS-basierte Hosts, um eine vollständige WLAN-Lösung bereitzustellen. Hochgeschwindigkeits-SPI- und SDIO-Hostschnittstellen sorgen für Flexibilität und Durchsatz.
Verwenden Sie WF200S für eine sichere Verbindungsschnittstelle zwischen dem Host und dem Transceiver.
