The Wio‑E5‑LE module is built with a single-core STM32WLE5JC chip, an ARM Cortex M4 MCU, and the SX126X transceiver. Designed for efficiency, it delivers up to 84% lower transmission power consumption compared to the standard Wio‑E5. Thanks to its ultra‑low energy usage, the Wio‑E5‑LE stands out as a highly power‑saving solution, making it ideal for applications that demand minimal energy consumption.
This compact unit offers versatile (G)FSK and Long Range support, compatibility with LoRaWAN® Class A/B/C protocols, and a broad frequency range including EU868/US915/AU915/AS923/KR920/IN865. Easily connect with LoRaWAN servers like TheThingsStack and Chirpstack.
Features
- Ultra-Low Power Consumption: In transmit mode, the operating current is only 26mA.
- High Performance: The transmit power is 14dBm @868/915MHz; -136.5dBm sensitivity for SF12 with 125KHz BW
