Wio-E5 Wireless Module (Bulk), for Long Range Application


Wio-E5 Long Range module is designed with ST system-level package chip STM32WLE5JC, ARM Cortex M4 ultra-low-power MCU and Long Range SX126X. It supports (G)FSK mode and Long Range . 62.5kHz, 125kHz, 250kHz, and 500kHz bandwidth can be used in Long Range mode, making it suitable for the design of various IoT nodes, supporting EU868 and US915.


Special note

This is the Bulk package version, we will deliver any quantity of modules independently in bulk. If you prefer like shipping the modules in tape reel, please refer to the Tape Reel version.


Please note that the newly released Wio-E5 CAN Development kit is based on the Wio-E5 module with a built-in CAN controller MCP2515 and supports CAN FD, CAN2.0, and RS485 communication. It is a good tool for both Long Range sensor network management and Car Hacking.

Wio-E5 is a low-cost, ultra-low power, extremely compact, and high-performance Long Range Module designed by Seeed Technology Co., Ltd. It contains ST system-level package chip STM32WLE5JC, and this STM32WL module is the first SoC integrated with the combo of Long Range RF and MCU chip. This module is also embedded with ARM Cortex M4 ultra-low-power MCU and Long Range SX126X and therefore supports (G)FSK mode and Long Range .

The previous versions of the Long Range module all require additional use of MCU (Microcontroller) to run the application code. Now, you can directly and immediately put the Wio-E5 STM32WLE5JC Module into use to complete this process without the hustle of additional accessories. With the Stamp Hole form factor, Wio-E5 enables you to integrate this module on your device’s mainboard conveniently. You don’t need to waste time and effort on designing your own device from scratch with the use of MCU and Long Range chip. Moreover, the module has already been certificated, so your completed device can be certified and approved by any agency cheaply and rapidly. Thanks to the innovative design, Wio-E5 has a comparatively lower cost than other Long Range modules. This will greatly save your budget in the whole process of product design.

Wio-E5 Long Range module is highly suitable for long-distance, ultra-low-power applications such as smart agriculture, smart city, wireless meter reading, sensor networks, wireless communication, and other low-power wide-area IoT scenarios. If you want a module to design your own Long Range sensor, to construct IoT nodes, or to support any wireless communication applications, Wio-E5 is the premium choice that provides you with an optimal user experience.

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.

Application Note

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

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, developers 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

2.1 HSE

  • 32MHz TCXO

  • TCXO power supply: PB0-VDD_TCXO

2.2 LSE

  • 32.768KHz crystal oscillator

3. RF Switch

Wio-E5 module ONLY transmits through RFO_HP:

  • Receive: PA4=1, PA5=0

  • Transmit(high output power, SMPS mode): PA4=0, PA5=1
