Wio-E5-LE Wireless Module (Tape Reel) - STM32WLE5JC, ARM Cortex-M4 and SX126x embedded, supports LoRaWAN on EU868 & US915

The Wio-E5-LE module, powered by the STM32WLE5JC chip, incorporates a Cortex M4 MCU and an SX126X. It boasts a 76% reduced transmit current compared to Wio-E5, making it optimal for ultra-low power applications.

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.

• Ultra-Low Power Consumption: In transmit mode, the operating current is only 26 mA.
• 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.

The Wio-E5-LE module's Stamp Hole form factor allows seamless integration into a device's mainboard, eliminating the need for extra components. With versatile GPIO interfaces including UART, I2C, and ADC, developers have the flexibility to expand peripherals effortlessly. Furthermore, these pre-certified modules expedite the certification and regulatory approval process for your end products.

For beginners, the Wio-E5-LE simplifies the creation of prototypes or applications with its built-in AT command firmware, requiring just a few basic commands. Meanwhile, experienced developers can harness the SDK to design customized products.

Wio-E5 Series Comparison

Note

Should you prioritize transmission distance and be less concerned about power consumption, the Wio-E5 would be an ideal choice. Conversely, if minimizing power consumption is your primary objective and your operational range is relatively short, the Wio-E5-LE would be a more fitting selection.
