LoRa-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 LoRaWAN wireless IoT device with a long-distance transmission range.
LoRa-E5 mini is embedded with LoRa-E5 STM32WLE5JC Module, which delivers the world-first combo of LoRa 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 LoRa chip and supports LoRaWAN protocol on the worldwide frequency and (G)FSK, BPSK, (G)MSK, and LoRa modulations. (Learn more about LoRa-E5)
LoRa-E5 mini leads out all GPIOs of LoRa-E5, including UART, ADC, SPI, IIC, and etc. It contains RESET and BOOT buttons and is use-friendly. Supporting LoRaWAN protocol, LoRa-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 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°C ~ 85°C, high sensitivity between -116.5dBm ~ -136 dBm, and power output up to +20.8 dBm at 3.3V.
Since LoRa-E5 is a LoRaWAN chip with an MCU, there are three main ways to utilize the LoRa-E5 mini:
There is a built-in USB to UART function on board, you could connect the LoRa-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.
For example, connect LoRa-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.
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 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.

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.
