LoRa-E5 is a low-cost, ultra-low power, extremely compact, and high-performance LoRaWAN Module designed by Seeed Technology Co., Ltd. It contains ST system-level package chip STM32WLE5JE, and STM32WLE5 is the first SoC integrated with the combo of LoRa RF and MCU chip. This module is also embedded with ARM Cortex M4 ultra-low-power MCU and LoRa SX126X and therefore supports (G)FSK mode and LoRa.

Features:

Ultra-low Power Consumption: as low as 2.1uA sleep current (WOR mode)
Extremely Compacted Size: 12mm x 12mm x 2.5mm 28 pins SMT
High Performance: TXOP=22dBm@868/915MHz; -136.5dBm sensitivity for SF12 with 125KHz BW
Long Distance Use: 158dB link budget
Wireless Connectivity: Embedded LoRaWAN protocol, AT command, support global LoRaWAN frequency plan
Worldwide Compatibility: wide frequency range; EU868/US915/AU915/AS923/KR920/IN865
Great Flexibility: For customers who want to develop software on the MCU of the module, other GPIOs of the MCU can be easily manipulated, including UART, I2C, ADC, etc. These rich GPIO interfaces are useful for users who need to expand peripherals.
