Key Features
-On the basis of WiFi LoRa 32, it’s has a smaller size, 0.49″ OLED display, and better RF characteristics.
-CE Certificate;
-Microprocessor: ESP32 (dual-core 32-bit MCU + ULP core), with LoRa node chip SX1276/SX1278;
-Micro USB interface with a complete voltage regulator, ESD protection, short circuit protection, RF shielding, and other protection measures;
-Onboard SH1.25-2 battery interface, integrated lithium battery management system (charge and discharge management, overcharge protection, battery power detection, USB / battery power automatic switching);
-Integrated WiFi, LoRa, Bluetooth three network connections, onboard Wi-Fi, Bluetooth dedicated 2.4GHz metal 3D antenna, reserved IPEX (U.FL) interface for LoRa use;
-Onboard 0.49-inch 64*32 dot matrix OLED display, which can be used to display debugging information, battery power, and other information;
-Integrated CP2102 USB to serial port chip, convenient for program downloading, debugging information printing;
-Support the ARDUIN0 development environment;
-(Exclusive) Supports the ARDUIN0 version of the ESP32 + LoRaWAN protocol routine provided by Heltec. This is a standard LoRaWAN protocol that can communicate with any gateway/base station running the LoRaWAN protocol (requires serial number activation, only the development of the company) The board is available, the serial number can be queried on this page);
-With good RF circuit design and basic low-power design (sleep current ≤800uA), it is convenient for IoT application vendors to quickly verify solution and deploy applications;

Notes:
① – Type:
Dev-Board – Can be used directly;
Module – Only core function, need to cooperate with external PCB or circuit.
② – Lithium: All lithium battery socket for Heltec boards is SH1.25-2;
③ – Vext: 3.3V(500mA) output, for external devices (e.g. sensors) power supply, in deep sleep mode, Vext can be shut down via software;
④ – Low Power: Products’ low power design, of Whole Circuit, the measured data are the current of the system during deep sleep.
