The Wio‑E5 wireless module integrates the STM32WLE5JC system-level chip, an ARM Cortex M4 ultra-low-power MCU, and the SX126X Long Range transceiver. Designed for efficiency, it supports LoRaWAN frequency plans including EU868, US915, and others. This makes it an excellent choice for wireless sensor networks and diverse IoT devices that demand battery-powered operation, low energy consumption, and extended communication range. Features Note: For antenna selection of Wio‑E5, we provide two references to improve RF performance and comply with CE/FCC regulations: 1. Dipole Antenna (up to 2.0 dBi): This antenna was used for Wio‑E5 certification. For more information, please refer to the certification report or SKU 113070002. 2. Spring-loaded Antenna (up to 1.1 dBi): This antenna is used by the SenseCAP S210X LoRaWAN sensor. This ultra-compact module has extremely low power consumption and supports both (G)FSK and Long Range. With integrated AT command firmware, developers can easily build prototypes or applications. It fully supports LoRaWAN® protocols and various frequency plans, making it an ideal solution for long-range sensor nodes and a wide range of wireless communication applications. Whether for wireless meter reading, IoT nodes, or sensor networks – the Wio‑E5 is perfectly suited for LPWAN IoT scenarios. With this module, you can connect to different LoRaWAN server platforms such as TheThingsStack, Chirpstack, and others.
