In order to meet the user’s requirements for Ultra-Low-Power and standard LoRaWAN protocol, we designed this product. On the basis of STM32L151CBU6MCU and SX1278 LoRa chip(433、470MHz), the low power current can reach to 6uA.

This product can’t meet your needs? Choose from our LoRa Node Family.

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

  • 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.
