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 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 for development environment. We provide ESP32 + LoRaWAN protocol for 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. Document Link:https://github.com/HelTecAutomation/Heltec_ESP32 WiFi LoRa 32 is a classic IoT dev-board, 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: If the antenna protective soft is too long and cannot be installed into the LoRa , you can shorten the antenna protective soft and be careful not to damage the internal copper tube of the antenna. Due to different production batches, the color of the is random and cannot be specified, which does not affect use.Type:915MHzColour:WhiteMaterial:PCB+electronic components Package Contents:2 * ESP32 LoRa V3 Development Board4 * Pin2 * Antenna2 * Terminal line2 * case Only the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
