FreeRTOS evaluation support When it Absolutely Must Connect ^ Product Overview SX-SDMAH is an 802.11ah Wi-Fi HaLow SDIO/SPI module enabled by Morse Micro's MM6108. It features a host SDIO or SPI interface to operate with a processor or a microcontroller. It supports up to 8MHz channel bandwidth to improve the maximum data throughput in the countries allowing 8MHz usage. Its small footprint design with the integrated antenna connector saves the PCB space and allows a more flexible embedded system design. The SX-SDMAH also features high-transmission power to gain more distance and coverage. Data Transfer over Further Distances The SX-SDMAH features higher transmission power than other Wi-Fi HaLow modules enabled by MM6108 IC. It ensures the best performance in its data throughput over long distances, and also provides wide coverage of Wi-Fi HaLow radio signal. Improved Data Throughput The SX-SDMAH supports up to 8MHz channel bandwidth to allow data transmission at up to 32.5Mbps PHY bit rate. It will improve the user experiences with Wi-Fi HaLow in regions where 8MHz channel bandwidth usage is allowed. Improved data throughput also enhances the experience with a large-scale IoT network. SDIO Host Interface for Linux OS The SDIO host interface has been widely used in legacy Wi-Fi systems. The SX-SDMAH offers more options for the embedded system design. It also eliminates a performance constraint with certain processors with SPI interface. SPI Host Interface for RTOS The SX-SDMAH supports the SPI host interface for RTOS embedded systems. Small Footprint The SX-SDMAH is the small footprint module integrating the antenna connector to save PCB space and simplify the PCB design. • Wi-Fi HaLow™ access point • Ethernet wireless bridge • Wi-Fi extender • IP camera, thermography camera • GNSS receiver • Vehicle telemetry devices • High-end sensors (e.g. vibration sensors) • Access control system ^ Key Features • Complies with IEEE 802.11ah • 1/2/4/8MHz channel bandwidth support • Transmission power of +23dBm or higher (target) • Access point and station mode • SDIO/SPI interface • Power-saving mode • Modular certification for the United States and Canada (plan) • Linux/Free RTOS driver support
