``LoRa Node 151`` is a part of the “Heltec LoRa“ series, with the following features:

  • CE Certificate;
  • Microprocessor: STM32L151CCU6(ARM® Cortex®-M3 32-bit RISC core,support DFU mode) , with LoRa® node chip SX1276/SX1278;
  • Onboard user resources available: 256 Kbytes of Flash memory with ECC; 32 Kbytes of RAM; 8 Kbytes of true EEPROM with ECC; 128-byte backup register.
  • Micro USB interface with a complete voltage regulator, ESD protection, short circuit protection, and other protection measures;
  • 1/2 AA battery shell, use 1/2 AA Lithium chlorine sulfite battery (this battery can’t charge, but onboard USB / battery power automatic switching allows connect USB when the battery is assembled);
  • Reserve SMA antenna interface for LoRa use
  • Download the firmware via DFU or ST-LINK;
  • Provide complete LoRaWAN(ClassA/C) source code(support ABP and OTAA);
  • With good RF circuit design and basic low-power design (sleep current: 1.8uA), it is convenient for IoT application vendors to quickly verify solutions and deploy applications;
