    Features

    • Ultra-low power consumption and high performance

    • Easy testing and rapid prototyping

    • Full GPIOs led out to rich interfaces, including RS-485, Grove, and etc.

    • Global LoRaWAN® and LoRa frequency plan supported

    • Long-distance transmission range to 10km (ideal value in open area)

    Hardware Overview

    LoRa-E5 Dev Board features an ultra-long transmitting range, extremely low chip power consumption, and user-friendly interfaces.

     

    LoRa-E5 Dev Board has a long-distance transmission range of LoRa-E5 up to 10km in an open area. The sleep current of LoRa-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.

     

    LoRa-E5 Dev Board also has rich interfaces. Developed to unlock the full functionality of the LoRa-E5 module, LoRa-E5 Dev Board has led out full 28 pins of LoRa-E5 and provides 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 LoRa-E5 is a LoRaWAN chip with an MCU, there are three main ways to utilize the LoRa-E5 Dev Board:

     

    1. Connect LoRa-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 LoRa-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 LoRa-E5 Dev Board to another mainboard via UART and control by AT commands


    For example, connect LoRa-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 LoRa 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 LoRa-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.

    Applications

    • LoRa-E5 module Easy testing

    • Rapid prototyping of LoRa devices with LoRa-E5

    • Any long-distance wireless communication application development

    • LoRa and LoRaWAN application learn and research

    Factory AT Firmware

    LoRa-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 LoRa-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 LoRa-E5 Dev Board or LoRa-E5 mini), the module will stay in the bootloader, and keep transmitting "C" character every 1S at baud rate 115200.

    Attention

    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 LoRa-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.
