Microprocessor: ESP32 (dual-core 32-bit MCU + ULP core) with LoRa node chip SX1276; 8M Byte SDRAM and 8M Byte Flash, these features allow WiFi and Bluetooth to work simultaneously. +5V DC Micro-USB power input, with complete voltage regulator, ESD protection, short circuit protection, RF shielding and other protection measures; MA socket for LoRa, WiFi/Bluetooth antenna; Integrated CP2102 USB to serial port chip, convenient for program download and debugging information printin. Support for development environment. We provide ESP32 + LoRaWAN protocol for ® library, which is a standard LoRaWAN protocol that can communicate with any LoRa gateway running the LoRaWAN protocol. In order for this code to run, a license is required. WiFi and Bluetooth have been widely used in scenarios, especially in terms of communication speed, with obvious advantages. Now almost all mobile phones have integrated WiFi and Bluetooth functions, but the communication distance is their disadvantage. Is there any hardware that can combine the long-distance advantage of LoRa with the advantages of WiFi/Bluetooth? Wireless bridge is such a product. Based on ESP32 and SX1276 chips, with 8M Byte SDRAM and 8M Byte FLASH on board, WiFi and Bluetooth can work simultaneously. It is a bridge that converts "WiFi/Bluetooth - LoRa" signals to each other.
