The WioE5LE 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 WioE5. Thanks to its ultralow energy usage, the WioE5LE stands out as a highly powersaving 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
• Long-Distance Communication:Benefit from a 158dB link budget to ensure a seamless connection over extended distances.
• Abundant peripherals:Equipped with a variety of GPIO interfaces like UART, I2C, and ADC, this module offers great flexibility for developers looking to expand peripherals.
• Certified and Trusted:Wio-E5-LE is FCC and CE-certified, guaranteeing compliance with regulations and standards.
• Easy to Use:Has built-in AT command firmware and supports custom product development using an SDK.

Specification
