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;
u2463 – Low Power: Products' low power design, of Whole Circuit, the measured data are the current of the system during deep sleep.
Feature: -WiFi LoRa 32 is a classic IoT dev-board designed & produced by Heltec Automation(TM), it's a highly integrated product based on ESP32 + SX127x, it has Wi-Fi, BLE, LoRa functions, also Li-Po battery management system, 0.96u2033 OLED are also included. It's the best choice for smart cities, smart farms, smart home, and IoT makers.
-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 0.96-inch 128*64 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;
-We provide ESP32 + LoRaWAN protocol ARDUIN0 library, this is a standard LoRaWAN protocol that can communicate with any LoRa gateway running the LoRaWAN protocol. In order to make this code running, a unique license is needed. it can be found 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.
