RAK5802: WisBlock RS485 Interface Module

RAK5802 is a WisBlock IO that extends the WisBlock system with an industrial RS485 data transmission interface. A ready-to-use SW library and tutorial make it easy to connect any sensor that uses the RS485 interface. RAK5802 supports one RS485 interface and has a battery and 3.3V power output to power sensors. Additionally, an I2C interface connection is available on the crimp terminal. RAK5802 combined with RAK4631 WisBlock Core offers the solution for an interface to industrial sensors and actuators that support the RS485 interface. This interface is the bridge between such sensors and LoRaWan® communication, LoRa® point-to-point connections, or BLE. RAK5802 is ideal for battery-powered applications due to its low power consumption. Furthermore, the WisBlock system allows the complete module to be switched off to further reduce the system's power consumption.

## Technical Features

- Industry standard RS485 serial interface converter.
