Product Summary
The WB26 is a LoRaWAN node module built for long-range, low-power IoT connectivity. It provides 22 dBm transmit power and a receiver sensitivity of -137 dBm (SF=12, BW_L=125 kHz @ LoRa), allowing end devices to reach gateways over long distances while drawing only 2 uA in sleep mode. The module follows the LoRaWAN Alliance standard for Global frequency bands and supports Class A/C operating modes. A compact 22 x 18 x 3.0 mm footprint and a 1.8 V to 3.6 V supply range make it practical for space- and power-limited designs, while the UART interface with IPEX support keeps antenna integration straightforward.
Key Features
- 22 dBm transmit power extends uplink range for outdoor and industrial nodes where gateway density is limited.
- -137 dBm receiver sensitivity at SF=12 with BW_L=125 kHz helps maintain downlink reliability in weak-signal or long-distance conditions.
- 2 uA sleep current supports longer field life for battery-powered sensor nodes.
- 1.8 V to 3.6 V supply range fits common low-power MCU and battery rails without extra regulation stages.
- Class A/C operating modes let designers match the power profile to periodic reporting or lower-latency applications.
- Global frequency bands under the LoRaWAN Alliance standard give one module platform for worldwide deployments.

Models and Options
The WB26 is delivered as a single module platform; integration is defined by mode and antenna choices.
- Model: WB26; pictured configuration WB26-8D-A01 (global frequency band).
- Operating mode: Class A or Class C.
- Antenna: external antenna through an IPEX connector via the UART interface.
Materials and Structure
The module measures 22 x 18 x 3.0 mm and is built around a low-power LoRa radio supporting Global frequency bands. Signals and control pass over a UART interface, and the board supports an IPEX antenna connector for external antennas. The 2 uA sleep current reflects a low-power design intent suited to battery-driven nodes.
Applications
WB26 is intended for network nodes that require long-range, low-power links. Typical segments include:
- Smart Street Lights - remote switching and status reporting.
- Smart Agriculture - field sensing where cabling is impractical.
- Smart Logistics - asset and environment tracking across wide sites.
- Industrial Control - distributed monitoring and control endpoints.
- Instruments & Meters - metering and remote-reading devices.
