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 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 LoRa-E5 is a LoRaWAN chip with an MCU, there are three main ways to utilize the LoRa-E5 Dev Board:

 

 

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

 

 

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.

 

 

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 inlearning and documentdown 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.
