HT-HC01 is a compact, high-performance Wi-Fi HaLow module designed for long-range, low-power IoT applications. Operating in the 902–928 MHz sub-1 GHz band and compliant with the IEEE 802.11ah standard, it delivers data rates up to 32.5 Mbps @ 8 MHz and supports transmission distances of 1–2 km. Featuring a small LLC package with 38 header pins, it integrates easily into various PCBs. The module includes an ultra-long-range PA, high-linearity LNA, T/R switch, and a 32 MHz crystal oscillator, simplifying Wi-Fi HaLow connectivity for external hosts. Its low-power design supports hibernate modes and is ideal for battery-operated devices, extending battery life. With interfaces like SDIO 2.0 and UART, and an integrated DC-DC converter supporting 3.0V to 3.6V, HT-HC01 is a versatile solution for applications in smart homes, industrial automation, asset tracking, and more.

Slower clock speeds will impact the maximum achievable throughput. At a minimum, 2 x GPIOs are required as a CMOS output to drive the RESET and WAKE signals. If power save is used, a third GPIO is needed, set as a CMOS input to receive the BUSY signal from the module. The SDIO data and command lines should be pulled up with 10k-100k resistors as per the SDIO 2.0 specification. What are the requirements for SPI host？ When selecting a CPU host to interface via SPI to the MM6108-MF08551 module, consider the following recommendations to achieve the best throughput: The host should support level-triggered interrupts. The host should support full-duplex SPI mode. The host should support DMA backed transactions on the SPI bus. What are the precautions for digital interfaces？ All unused digital IO pins must be pulled up or down to ensure they do not float. Failure to do so will result in a higher leakage current on the VDDIO supply.
