Description

The Wio-E5-LE mini provides access to all GPIOs of the Wio-E5-LE, including UART, ADC, SPI, I2C, and more. It contains reset and boot buttons for ease of use. Supporting LoRa protocol, the Wio-E5-LE mini enables ultra-long-range transmission up to 10km and ultra-low power consumption - the sleep current of the on-board Wio-E5-LE module is as low as 2.1uA (WOR mode).

Beyond the Wio-E5-LE mini, we also offer the Wio-E5-LE Dev Kit with more complex interfaces and capabilities to unlock the Wio-E5-LE module's full potential. It provides a wide range of access protocols and abundant interface types, enabling rapid testing and prototyping with RS-485, Grove interfaces, and plentiful GPIOs.

Additionally, the Wio-E5-LE module has already been certified, allowing your finished devices to be certified and approved rapidly and cost-effectively.

Since Wio-E5-LE is a Long Range chip with an MCU, there are three main ways to utilize the Wio-E5-LE mini:

  1. Connect Wio-E5-LE mini to PC and control it using AT commands

There is a built-in USB to UART function on board, you could connect the Wio-E5-LE mini to your PC with a USB type C cable, and use serial communication software to send AT commands and read data from the board.

  1. Connect Wio-E5-LE mini to another mainboard via UART and control it using AT commands sent through the UART connection

For example, connect Wio-E5-LE mini to Seeed Studio XIAO and the Expansion Board via UART, and send AT commands and read data from Seeed Studio XIAO through Arduino IDE serial monitor.

  1. User Application Development by using SDK

Develop your own Long Range development board with MCU function by using STM32Cube Programmer, which is the SDK officially provided by STMicroelectronics. To download this SDK resource, please click here.

With its outstanding features including long-range transmission, ultra-low power consumption, and abundant interfaces, the Wio-E5-LE mini is an excellent choice for developing, testing, and prototyping IoT devices and applications requiring long-range and low-power connectivity. It is ideal for use cases across smart agriculture, offices, industry, and other fields.
