Heltec HTIT-WB32LA_V3 Lora Wifi Development Board SX1262 ESP32 Display Module
Description:
WiFi LoRa 32 is a classic IoT dev-board, it has been loved by developers and makers. 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.
- 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.

Different between V2 and V3
1. MCU is different. V2 uses ESP32-D0WDQ6, and V3 uses ESP32-S3FN8. This results in different GPIO pin definitions.
2. LoRa chips are different. V2 uses SX1276/8, and V3 uses SX1262.
3. The USB interface is different. V2 uses Micro USB, and V3 uses USB Type-C.
