Description

The LoRaE5 Dev Kit features an ultralong transmitting range , extremely low chip power consumption , and userfriendly interfaces . Developed to unlock the full functionality of the LoRaE5 module, it leads out 28 pins and provides rich interfaces including Grove connectors , RS485 , and male/female pin headers for easy connection to sensors and modules with different protocolssaving wiring time . Power can be supplied by a 2AA battery holder for temporary use when lacking external powerideal for quick testing and rapid prototyping .

Since LoRaE5 is a LoRaWAN chip with an MCU , there are three main ways to utilize the LoRaE5 Dev Board:

1. Connect via USB and control with AT commands .

Use the builtin USBtoUART functionconnect with a USB TypeC cable, then send AT commands and read data via serial software.

1. Connect via UART to another mainboard and control with AT commands .

For example, connect to Seeeduino XIAO and the Expansion Board via UART, then send AT commands and read data through the Arduino IDE serial monitor.

1. Develop user applications by using SDK .

Build your own LoRa development board with MCU functions using STM32Cube Programmer (official SDK by STMicroelectronics). To download this SDK, click here .

With the above outstanding features , the LoRaE5 Dev Board is a superior choice for IoT device development , testing , prototyping , and applications in longdistance, ultralow power scenarios like smart agriculture , smart office , and smart industry . The module is already certified , enabling faster and cheaper device certification.
