The Wi-Fi HaLow Board (FGH100M-H) operates in the 902–928MHz band, providing long-range, low-power wireless connectivity with strong signal penetration. Designed for smart home and IoT applications, it integrates seamlessly with the Seeed Studio XIAO ecosystem for reliable network performance. The Wi-Fi HaLow Board based on the FGH100M-H module is a high-performance, long-range Wi-Fi HaLow solution. Operating in the 902-928 MHz frequency band, it offers excellent penetration and coverage, making it ideal for smart home and IoT applications. With its compact design and compatibility with the Seeed Studio XIAO ecosystem, this card ensures reliable and efficient connectivity for various projects. This expansion board is currently not directly compatible with the XIAO nRF54L15 series because Arduino is not supported. However, the hardware interface is fully compatible, and developers can manually adapt the software if needed. Official software support from Seeed Studio is under development - stay tuned for updates! Features * Long-Range Connectivity: Complies with IEEE 802.11ah standard, operating in 902-928 MHz frequency band, providing coverage up to 1 km with superior penetration performance. * Low Power Consumption: Optimized power efficiency design, making it ideal for power-sensitive IoT applications. * Robust Security: Implements comprehensive security features including AES, SHA-256, SHA-384, SHA-512, and WPA3 encryption. * Seamless Integration with Seeed Studio XIAO Boards: Sized at 42 x 25mm, it's compatible with the Seeed Studio XIAO Boards (Pre-Soldered) via easy snap-on. (We recommended to use XIAO ESP32 series.)
