Microprocessor: ESP32-S3FN8 (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, Blue-tooth three network connections, onboard WiFi, 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.<br><br>Integrated CP2102 USB to serial port chip, convenient for program downloading, and debugging information printing. Support the for Arduino development environment. We provide ESP32 + LoRaWAN protocol for 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.
