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. 

Wio-E5 mini is embedded with 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 ARM Cortex-M4 core and Semtech SX126X Long Range chip and supports Long Range protocol on the worldwide frequency and (G)FSK, BPSK, (G)MSK, and Long Range modulations.

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.

Wio-E5 mini leads out all GPIOs of Wio-E5, including UART, ADC, SPI, IIC, and etc. It contains RESET and BOOT buttons and is use-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). 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.
Other than the Wio-E5 mini, we also provide other choices including the Wio-E5 Development Board carrying 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.  (Learn more about Wio-E5 Development Board)
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.

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.

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.

Application Note

For more detailed information about how to use Wio-E5, please visit Wio-E5 (STM32WLE5JC) Module Wiki.


1. Factory AT Firmware

Wio-E5 series has a built-in AT command firmware, which supports Long Ragne Class A/B/C protocol and a wide frequency plan: EU868/US915/AU915/AS923/KR920/IN865. With this AT command firmware, users can easily and quickly build their prototype or application.

The AT command firmware contains a bootloader for DFU and the AT application. The "PB13/SPI_SCK/BOOT" pin is used to control Wio-E5 to stay in the bootloader or jump to the AT application. When PB13 is HIGH, the module will jump to AT application after reset, with a default baud rate of 9600. When PB13 is LOW (press the "Boot" button on Wio-E5 Dev Board or Wio-E5 mini), the module will stay in the bootloader, and keep transmitting "C" character every 1S at baud rate 115200.



1. Factory AT Firmware is programmed with RDP(Read Protection) Level 1, developers need to remove RDP first with STM32Cube Programmer. Note that regression RDP to level 0 will cause a flash memory mass to erase and the Factory AT Firmware can't be restored again.

2. The "PB13/SPI_SCK/BOOT" pin on the Wio-E5 module is just a normal GPIO, not the "BOOT0" pin of the MCU. This "PB13/SPI_SCK/BOOT" pin is used in the bootloader of the Factory AT firmware, to decide to jump to APP or stay in bootloader(for DFU). The real "BOOT0" pin doesn't pinout to the module, so developers need to be careful when developing low-power applications.
