CSW2200
CSW2200-23L LR-WiFi Module
CSW2200-23L is an SDIO radio module for embedded-board integration. IEEE 802.11b/g/n and private LR-WiFi links with dual-stream 802.11n MIMO support control, telemetry and video for cameras, unmanned devices, agriculture and industrial endpoints. It suits compact designs with Linux driver integration capability. Both endpoints require matching band and firmware configurations.
