2 Description
LoRa-E5 is embedded with high-performance STM32WLE5JC, which is very suitable for the design of various IoT
nodes.
Based on the development of the multi-mode high-performance SX126X chip, the LoRa-E5 module supports (G)
FSK mode and LoRa
®
. 62.5kHz, 125kHz, 250kHz and 500kHz bandwidth can be used in LoRa
®
mode.
Based on the powerful functions and rich peripherals of STM32WLE5JC, the module provides UART, I2C, SPI,
ADC and GPIOs for users to choose according to the application. If you need to upgrade the built-in AT command
firmware, please use the two-wire interface (UART) to complete the programming based on the boot mode; and
customers can develop the software based on the internal MCU of the module to complete the program erasure
and programming through SWD.
LoRa-E5 currently contains two sub-models, LoRa-E5-LF (Single-core STM32WLE5JC + SX126X) and LoRa-E5-HF
(Single-core STM32WLE5JC + SX126X), LoRa-E5-LF supports 22dBm @ LF band (470MHz); 10dBm @ LF band
(434MHz); LoRa-E5-HF supports 22dBm @ HF band (868 / 915MHz).
