High-Performance, Ultra-Long-Range, Ultra-Low-Power LoRaWAN+BLE Combo Module
The ME25LS02 is a high-performance, ultra-low-power LoRaWAN module supporting BLE 6.0 and LoRaWAN protocols. It features a dual-core MCU (ARM Cortex M33 & RISC-V), 256KB RAM, and 1.5MB Flash, making it ideal for long-range, low-power IoT applications.
With excellent reception sensitivity (BLE: -104dBm, LoRa: -126dBm) and high transmission power (BLE: +8dBm, LoRa: 22dBm), the module ensures reliable communication over extended distances. It operates at 3.3V, offers 27 GPIOs, and supports interfaces like USB, UART, and I2C. The open-source development platform enables easy customization and secondary development.
