More comparison between the Wio-E5 and RFM95 chip:


Grove - Wio-E5 can endow your development boards' strong features of ultra-long transmitting range, great performance, and high efficiency by easiliy plug and play with Grove connector on board. By connecting Grove - Wio-E5 to your development boards, your devices is able to communicate with and control Wio-E5 conveniently by AT command through UART connection. 


With all the outstanding features listed above, Grove Wio-E5 will be a superior choice for IoT device development, testing, and long-distance, ultra-low power consumption IoT scenarios like smart agriculture, smart office, and smart industry. It is designed with industrial standards with a wide working temperature at -40℃ ~ 85℃, high sensitivity between -116.5 dBm and -136 dBm, and power output between 10 dBm and 22 dBm.

Application Note

1. Factory AT Firmware

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

  1. Product Quality
    from order view
    Really good quality of the board. Good to explore the module, but I would suggest having more communication interfaces available in the board since the chip can handle it.

    I bought 2 and stablishing a communication channel between them was easy.
  2. Product Quality
    from order view
    Excellent build quality. Very tidy packaging. Really easy to get started and use. Switching to an external ipex antenna works better than the onboard antenna. Not sure if I need to desolder the coil antenna to use the ipex.
  3. Product Quality
    from order view
    Works well and looks well built, but I'm confused why only channels 0-2 can be selected for EU band.
  4. Product Quality
    from order view
    Superior product. After short testing, it works very nicely.
