Summary

●WiFi LoRa 32(V3) is a classic IoT dev board designed & produced by Heltec Automation.

●Since its launch in 2017, it has been loved by developers and makers.

●Widely used in numerous excellent open-source projects and directly made into products for LoRa/LoRaWAN features.

●The newly launched V3 version has the same pin sequence as the V2 version and retains Wi-Fi, BLE, LoRa, OLED display, and other functions.

●It is the best option for smart cities, farms, homes, industrial control, house security, wireless meter reading, and IoT developers.

Main Features

● Microprocessor: ESP32-S3FN8 (Xtensa® 32-bit LX7 dual-core processor, five-stage pipeline rack Structure, frequency up to 240 MHz).

● SX1262 LoRa node chip.

● Type-C 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).

● Onboard 0.96-inch 128*64 dot matrix OLED display can be used to display debugging information, battery power, and other information.

● Integrated WiFi, LoRa, Bluetooth three network connections, onboard Wi-Fi, Bluetooth dedicated 2.4GHz metal spring antenna, reserved IPEX (U.FL) interface for LoRa use.

● Integrated CP2102 USB to serial port chip, convenient for program downloading, and debugging information printing.

● Support the Arduino development environment.

● With good RF circuit design and low-power design.
