Seeed Studio 317990687 - LoRa-E5 LoRaWAN module featuring STM32WLE5JC and LoRa SX126X.
LoRa-E5 LoRaWAN module is designed with ST system-level package chip STM32WLE5JC, ARM Cortex M4 ultra-low-power MCU and LoRa SX126X. It supports (G)FSK mode and LoRa. 62.5kHz, 125kHz, 250kHz, and 500kHz bandwidth can be used in LoRa® mode, making it suitable for the design of various IoT nodes, supporting EU868 and US915.
This LoRa E5 module is designed with industrial standards, hence it's highly suitable to be used in designing industrial IoT products, with a wide working temperature at -40℃ ~ 85℃.
