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.
``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;
