Hardware Overview


Wio-E5 Dev Board features an ultra-long transmitting range, extremely low chip power consumption, and user-friendly interfaces.
Wio-E5 Dev Board has a long-distance transmission range of Wio-E5 up to 10km in an open area. 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 -116.5 dBm ~ -136 dBm, and power output up to +20.8dBm at 3.3V.
Wio-E5 Dev Board also has rich interfaces. Developed to unlock the full functionality of the Wio-E5 module, Wio-E5 Dev Board has led out full 28 pins of Wio-E5 and provides with rich interfaces including Grove connectors, RS-485 terminal, male/female pin headers for you to connect sensors and modules with different connectors and data protocols, saving your time on wire soldering. You could also easily power the board by connecting the battery holder with 2 AA batteries, enabling temporary use when lacking an external power source. It is a user-friendly board for easy testing and rapid prototyping.
Since Wio-E5 is a Long Range chip with an MCU, there are three main ways to utilize the Wio-E5 Dev Board:
1. Connect Wio-E5 Dev Board to PC via USB and control by AT commands

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

For example, connect Wio-E5 Dev Board 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. Develop user application 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 Dev Board 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.

1. Factory AT Firmware

Wio-E5 series has a built-in AT command firmware, which supports Long Range 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.

2. Clock Configuration
