Seeed Studio Wio-E5 Mini Dev Board STM32WLE5JC LoRaWAN EU868 US915

Wio-E5 mini Dev Board builds in and leads out full GPIO of theWio-E5 STM32WLE5JC LoRa module.Supporting Long Range protocol and global frequency, the Wio-E5 mini is able to achieve a transmission range of up to 10 km in open areas. It supports EU868 and US915, making it suitable for wireless sensor networks and other IoT devices that require battery power, low power consumption and long range.

Wio-E5 mini is a compacted-sized development board suitable for the rapid testing and building of small-size prototyping and helps you design your ideal Long Range wireless IoT device with a long-distance transmission range.

This ultra-compact module has extremely low power consumption and is capable of supporting both (G)FSK and Long Range. With its built-in AT command firmware,makes it easy for developers to build their prototypes or applications. It can easily support LoRaWAN protocols and a variety of frequency plans, making it an ideal solution for Long Range sensor nodes and a range of wireless communication applications. Whether you need to set up Wireless Meter Reading, IoT Nodes, or a Sensor Network, the Wio-E5 is perfectly suited for low power wide area IoT scenarios.

With this module, you can connect to different LoRaWAN server platforms like TheThingsStack, Chirpstack, and others.

Description

Wio-E5 mini leads out all GPIOs of Wio-E5, including UART, ADC, SPI, IIC, etc. It contains RESET and BOOT buttons and is user-friendly. Supporting Long Range protocol, Wio-E5 mini features ultra-long-range transmission and ultra-low power consumption: it is able to achieve a transmission range of up to 10 km, and the sleep current of Wio-E5 modules on board is as low as 2.1 uA(WOR mode). Other than the Wio-E5 mini, we also provide other choices including theWio-E5 Development Boardcarrying more complex interfaces and features to unlock the more powerful performance of the Wio-E5 module. It provides a broader range of access protocols and superabundant types of interfaces. Thus you are able to test and prototype the module rapidly with RS-485, Grove interfaces, and rich GPIOs.

Additionally, the module has already been certificated, so your completed device can be certified and approved by any agency cheaply and rapidly.

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

1. Connect Wio-E5 mini to PC and control by AT commands

There is a built-in USB to UART function on board, you could connect the Wio-E5 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 mini to another mainboard via UART and control by AT commands

For example, connect Wio-E5 mini to Seeeduino XIAO and the Expansion Board via UART, and send AT commands and read data from Seeeduino 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 clickhere.

With all the outstanding features listed above, the Wio-E5 mini will be a superior choice for IoT device development, testing, prototyping, and applications in long-distance, ultra-low power consumption IoT scenarios like smart agriculture, smart office, and smart industry.
