Feature:
WiFi and Blue tooth have been widely used in various scenarios, especially in terms of communication speed, which have obvious advantages. Almost all mobile phones now integrate WiFi and Blue tooth functions, but the communication distance is their shortcoming. Is there any hardware that can combine the long-distance advantages of LoRa with the advantages of WiFi/Blue tooth?
Wireless Bridge is such a product. Based on ESP32 and SX1276 chips, onboard 8M Byte SDRAM and 8M Byte FLASH, WiFi and Blue-tooth can work at the same time. It is a bridge that converts “WiFi/Blue tooth – LoRa” signals to each other.
- 8M Byte SDRAM and 8M Byte FLASH, these features will allow WiFi and BlueTooth to work at the same time.
- +5V DC Micro USB power input, with a complete voltage regulator, ESD protection, short circuit protection, RF shielding, and other protection measures;
- SMA socket for LoRa, WiFi/Blue Tooth antenna;
- Integrated CP2102 USB to serial port chip, convenient for program downloading, debugging information printing;
- Microprocessor: ESP32 (dual-core 32-bit MCU + ULP core), with LoRa node chip SX1276;
