Description
Seeed Studio Wi-Fi HaLow Transceiver for XIAO is a compact Wi-Fi HaLow XIAO board based on the Quectel FGH100M-H module. It brings IEEE 802.11ah sub-1GHz networking to the Seeed Studio XIAO ecosystem, giving compact IoT endpoints longer range, better wall penetration, and lower-power wireless behavior than ordinary short-range Wi-Fi.
This FGH100M-H Wi-Fi HaLow board is designed for XIAO-based endpoint development, remote sensors, smart home devices, agricultural IoT, environmental monitoring, and smart city nodes. When paired with a gateway-side HaLow device, the Seeed XIAO Wi-Fi HaLow module can be part of a long-range IP-based IoT network instead of a tiny-payload telemetry-only system.
Regional note: this board operates in the 902-928 MHz band. Confirm local radio regulations before using it in a deployed product.
Features
- Wi-Fi HaLow / IEEE 802.11ah: long-range sub-1GHz wireless networking for compact IoT nodes.
- XIAO ecosystem design: the Wi-Fi HaLow XIAO board uses a compact expansion form factor for Seeed Studio XIAO projects.
- FGH100M-H module platform: supports 902-928 MHz operation, 1 x 1 antenna, and up to 32.5 Mbps 802.11ah physical rate.
- Endpoint-side role: STA mode makes the Seeed XIAO Wi-Fi HaLow module suitable for client devices connecting into a HaLow network.
- Security features: supports AES, SHA-256, SHA-384, SHA-512, and WPA3.
- External antenna support: IPEX antenna connector helps adapt the FGH100M-H Wi-Fi HaLow board to enclosure and range requirements.

Other Content
The Seeed Studio Wi-Fi HaLow Transceiver for XIAO is best understood as an endpoint-side FGH100M-H Wi-Fi HaLow board. A practical long range IoT network often uses this Wi-Fi HaLow XIAO board on the client side and a Mini PCIe HaLow module on the infrastructure or gateway side.
Official Seeed guidance uses XIAO ESP32S3 and the MM-IoT SDK workflow for software development. The FGH100M-H Wi-Fi HaLow board is not just a range extender; it is part of a real Wi-Fi HaLow network topology.
For a long range IoT endpoint, the Seeed XIAO Wi-Fi HaLow module gives XIAO projects an IEEE 802.11ah wireless path without moving to a large gateway form factor. This makes the board useful for long range IoT sensors, compact control nodes, and field devices.
