WisBlock RAK5802 RS485 Module

The RAK5802 adds an industrial RS485 interface to a WisBlock node. The TP8485E from 3PEAK converts the RS485 signals into UART signals for the core module. This allows, for example, Modbus sensors to be read via LoRaWAN.

WisBlock from RAK Wireless is a modular system for building custom LoRaWAN and IoT nodes. Core, sensor and IO modules are plugged onto a base board and screwed in place.

Recommended Accessories:

• WisBlock RAK19007 Base Board 2nd Gen
• WisBlock RAK19001 Dual IO Base Board
