Availability: 2955 In Stock



Based on ultra low power design, we launched LoRa Node 151, adopting the STM32L151CCU6 MCU (support DFU mode) and SX127x LoRa chip, use 1/2 AA Lithium chlorine sulfite battery. Enter low power mode under the standard LoRaWAN protocol, the Deep Sleep Current ≤ 1.8uA.


  • CE Certificate;
  • Microprocessor: STM32L151CBU6 (Ultra-low-power ARM Cortex-M3 MCU with 128 Kbytes Flash), with LoRa node chip SX1278 (433MHz ~ 510MHz);
  • Micro USB interface with a complete voltage regulator, ESD protection, short circuit protection, and other protection measures;
  • Onboard SH1.25-2 battery interface, integrated lithium battery interface, integrated battery management system (battery power detection, USB / battery power automatic switching);
  • Integrated CP2102 USB to serial port chip, convenient for program downloading, debugging information printing;
  • This product supports DFU mode download (need to cooperate with relevant download software).
  • System resource:FLASH – 128K, RAM – 16K, EEPROM – 4K;
  • User available resources: FLASH – 64K, RAM – 8K, EEPROM – 4K;
  • Provide standard LoRaWAN protocol routines.
  • With good RF circuit design and basic low-power design (sleep current ≤7uA), it is convenient for IoT application vendors to quickly verify

    LoRaWAN protocol easily.
