Wio-E5 Mini Development Board (STM32WLE5JC)

The Seeed Wio-E5 Mini is a compact development board suitable for the rapid testing and building of small-size prototypes, helping you to design your ideal Long Range wireless IoT device with a long-distance transmission range.

The Wio-E5 Mini is embedded with the Wio-E5 STM32WLE5JC module, which delivers the world-first combo of Long Range RF and MCU chip into one single tiny chip and is FCC and CE certified. It is powered by an ARM Cortex-M4 core and Semtech SX126X Long Range chip, supports Long Range protocol on the worldwide frequency and (G)FSK, BPSK, (G)MSK and Long Range modulations.

The board leads out all GPIOs of the Wio-E5, including UART, ADC, SPI and IIC. It contains RESET and BOOT buttons and is user-friendly. Supporting Long Range protocol, the 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). It is designed with industrial standards with a wide working temperature at -40 ℃ ~ 85℃, high sensitivity between -116.5dBm ~ -136 dBm, and power output up to +20.8 dBm at 3.3V.

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.

Comes complete with an antenna, USB-C cable, headers and sticker.

Utilising the board

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

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.

2. 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.

3. 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 find the resources in learning and document down below.
