LoRa-E5 mini STM32WLE5JC - LoRaWAN 868/915 MHz module - Seeedstudio 113990939
LoRa-E5 mini is a compact communication module in LoRaWAN standard, created by Seeedstudio. The module allows for long-range communication in LoRaWAN standard in the band of 868 MHz and 915 MHz, so it can be used both in the European Union and the United States. The used STM32WLE5JC chip allows for data transmission within a range of up to 10 km. The chip is based on ARM Cortex-M4 core and Semtech SX126X LoRa core which supports LoRaWAN protocol and GFSK, BPSK, GMSK and LoRa modulations.

Interfaces in the LoRa-E5 mini
The module with LoRa chip has all its GPIOs pinned out on 2.54mm pins, these are interfaces like UART, ADC, SPI, I2C. It has a built-in RESET and BOOT button. LoRa-E5 mini is a module with very long wireless communication range and ultra low power consumption. It allows sending and receiving data up to 10 km, and its resting current consumption is 2.1 uA (WOR mode). It is designed for industrial standards, and can operate from -40°C to 85°C, with sensitivity from -116.5 dBm to -136 dBm, and output power up to 20.8 dBm at 3.3 V.

How to use LoRa-E5 mini
- Using AT commands - board has built-in USB - UART converter, so you can program the board connected to computer using AT commands.
- Using UART interface - LoRa-E5 mini can communicate with another module, e.g. Seeeduino XIAO via UART interface and send and receive AT commands.
- Create user applications using SDK - with the provided SDK files you can create your own LoRa board with MCU functionality using STM32Cube programmer.
What is LoRa?
LoRa or LoRaWAN is a very low power long range wireless communication protocol. The LoRa protocol in the LoRa E5-mini module uses sub-gigahertz free radio frequencies such as 868 MHZ (Europe) or 915 MHZ (North America).
