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


-Microprocessor: ESP32 (dual-core 32-bit MCU + ULP core + Internal 4MB FLASH), with LoRa node chip SX1276;
-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;
-Integrated CP2102 USB to serial port chip, convenient for program downloading, debugging information printing;
-Support the Aduino development environment;
-(Exclusive) Supports the Aduino 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 good low-power design (sleep current Ôëñ 30uA), it is convenient for IoT application vendors to quickly verify solution and deploy applications;
