Product Features:
1. All-in-one, plug-and-play design: Includes a V4 main control board and an aluminium alloy + PC housing; optional accessories include a battery, antenna and L76K GNSS module, allowing for deployment straight out of the box.
2. High-performance combination: The ESP32-S3R2 development board (2MB PSRAM + 16MB Flash) works in conjunction with the SX1262 to support high-power 27dBm LoRa long-range communication.
3. Ultra-low power design: Standby current of just 20μA, with native support for solar charging management, optimised specifically for outdoor battery-powered scenarios.
4. Flexible human-machine interaction: Available in either a 320×240 touchscreen version or a tempered glass window version, balancing real-time monitoring with OLED compatibility.
5. Industrial-grade expandability: Features a built-in B2B socket, SMA antenna port and physical buttons, supporting seamless integration of multiple sensors and the construction of customised IoT systems.
Introduction
The WiFi LoRa 32 Expansion Kit is a comprehensive kit designed specifically for the WiFi LoRa 31 series, including a protective case, expansion carrier board and sensor modules. You can view 3D models and customise product parameters on the MQB platform to assemble a kit that meets your requirements. The WiFi LoRa 32 V4 Expansion Kit comes complete with the V4 board and pre-installed accessories, eliminating the need to source compatible parts or deal with loose components. It is ideal for rapid prototyping and field deployment of Meshtastic nodes, LoRaWAN sensors and IoT monitoring systems. Simply insert the circuit board, connect the antenna, and power on to get your project started.
