Seeed Studio Wio-E5-LE LoRa® Wireless Modules
Seeed Studio Wio-E5-LE LoRa® Wireless Modules offer 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. The devices exemplify power efficiency with an unprecedentedly low power consumption profile, marking a significant improvement over Wio-E5. The module's energy-saving design makes it an ideal candidate for a wide range of applications that require minimized power usage. The compact modules use an ST STM32WLE5JC system-level package chip, embedded high-performance SX126X LoRa chip, and ultra-low power consumption MCU. Target applications include wireless sensor networks and other Internet of Things (IoT) devices, especially battery-powered low-power consumption and long-distance occasions.
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 can effortlessly expand peripherals. These pre-certified modules also expedite end product certification and regulatory approval process.
