Integrated WiFi, LoRa, Bluetooth three network connection, on-board Wi-Fi,, Bluetooth dedicated 2.4GHz metal spring antenna, reserved IPEX(U.FL) interface for LoRa. The On-board display unit is a 0.96-inch 128 * 64 dot-matrix OLED display that can be used to display debugging information, battery power, and other information. Integrated CP2102 USB turn serial port chip, convenient program download, debugging information printing. Support for development environment. We provide the ESP32 + LoRaWAN protocol for library, which is a standard LoRaWAN protocol available with running the LoRaWAN protocol. The new V3 version has the same pin sequence as the V2 version, and retains the Wi-Fi, BLE, LoRa, OLED display, and other features. It is the for smart city, farm, home, industrial control, housing security, wireless meter reading, and Internet of Things developers. It has good RF circuit design and low power consumption design.
