Summary
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.
Main Features
- CE Certificate;
- Microprocessor: STM32L151CBU6 (Ultra-low-power ARM Cortex-M3 MCU with 128 Kbytes Flash), with LoRa node chip SX1278 (433MHz ~ 510MHz);
- 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;
