Notes:
Type:
Dev-Board, Can be used directly;
Module: Only core function, need to cooperate with external PCB or circuit.
Lithium: All lithium battery socket for Heltec boards is SH1.25-2;
Vext: 3.3V(500mA) output, for external devices (e.g. sensors) power supply, in deep sleep mode, Vext can be shut down via software;
Low Power: Products low power design, of Whole Circuit, the measured data are the current of the system during deep sleep.
Feature:
-In order to meet the user, 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.
-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, RAM16K, 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.
