The Seeed Studio WM1302 (915 MHz) is a LoRaWAN concentrator module built on Semtech's SX1302 baseband with dual SX1250 front ends. In a mini-PCIe form factor with an SPI interface, it turns a Raspberry Pi or similar host into a full 8-channel LoRaWAN gateway for indoor or outdoor deployments.

Key specifications

• Semtech SX1302 baseband + 2x SX1250 TX/RX front ends
• 8-channel LoRaWAN concentrator, US 902–928 MHz variant
• Mini-PCIe form factor with SPI host interface
• Designed for Raspberry Pi gateway builds (via Pi Hat carrier)
• High sensitivity (down to -141 dBm) for long-range, high-capacity networks

The fastest path from a single-board computer to a production-grade LoRaWAN gateway.
