Seeed Studio LoRa-E5 STM32WLE5JC LoRaWAN Module is a low-cost, ultra-low power, extremely compact, and high-performance module. This module uses ST system-level package chip STM32WLE5JC, embedded high-performance LoRa® chip SX126X. The LoRa-E5 LoraWAN module is embedded with Arm Cortex M4 ultra-low-power MCU and LoRa SX126X, thus supports (G)FSK mode and LoRa. This module offers a 158dB link budget for long-distance use and features worldwide compatibility. The LoRa-E5 LoRaWAN module operates at a 3.3V supply voltage and -40°C to 85°C temperature range. Typical applications include wireless meter reading, IoT nodes, smart agriculture, smart city, sensor network, low power wide area IoT applications, and wireless communication.

    STM32WL is NOT a SiP! It embeds the Semtech radio IP, but is not a stacked die! It’s monolithic!
