Description

The Wio-E5-LE, embedded with the high-performance STM32WLE5JC, is perfectly suited for designing various IoT nodes. It leverages the multi-modal capabilities of the high-performance SX126X chip and supports (G) FSK mode and LoRa. In the LoRa mode, bandwidths of 62.5kHz, 125kHz, 250kHz, and 500kHz can be utilized.

As the newest addition to the Wio-E5 series, this powerful Long Range module also comes with pre-installed AT command firmware, simplifying the process for developers to create their prototypes or applications. With its support for LoRaWAN Class A/B/C protocol and a broad frequency plan, including EU868/US915/AU915/AS923/KR920/IN865, the module exhibits high versatility and adaptability in various low-power wide-area IoT scenarios such as smart agriculture, wireless meter reading, and smart city applications.

Leveraging the robust features and diverse peripherals of the STM32WLE5JC, the Wio-E5-LE module provides UART, I2C, SPI, ADC, and GPIOs, giving users the flexibility to choose as per their application requirements. For firmware upgrades, a two-wire interface (UART) is available for programming in line with the boot mode. Furthermore, the module’s internal MCU allows for software development for program erasure and programming via SWD.

With the Stamp Hole form factor, it is convenient to integrate into your device’s mainboard without the need for additional accessories. Additionally, the module has already been certified by FCC and CE, so your completed device can be certified and approved by any agency quickly and inexpensively.

Seeed is the official ST Authorized Partner to bring you STMicroelectronics solutions from Modules to Development Boards, one-stop prototyping services with Seeed Fusion, and integration customization.
