2Sets 868MHz 915MHz ESP32 LoRa V3 Development Board SX1262 0.96 Inch OLED Display BT+WIFI Lora Kit with Case for Arduino IOT Smart Home

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.

Note:
Not include battery;

 

If the antenna protective soft shell is too long and cannot be installed into the LoRa shell, you can shorten the antenna protective soft shell and be careful not to damage the internal copper tube of the antenna.

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).
- 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.
- Onboard 0.96-inch 128*64 dot matrix OLED display can be used to display debugging information, battery power, and other information.
- Integrated CP2102 USB to serial port chip, convenient for program downloading, and debugging information printing.
- Support the Arduino development environment.
- We provide ESP32 + LoRaWAN protocol Arduino® library, this is a standard LoRaWAN protocol that can communicate with any LoRa gateway running the LoRaWAN protocol. To make this code run, a unique license is needed.
- With good RF circuit design and low-power design.
