Product description: RS485 module - WisBlock IO extension - Rak Wireless RAK5802
RAK5802 extension is a converter of standard RS485 interface to a serial port. It has ESD 18 kV protection and low power consumption. It supports up to 16 RS485 nodes, automatically detects TX / RX signals. It is compatible with many WisBlock modules, it needs connection to WisBlock Base Board and WisBlock Core development modules to work properly.
On manufacturer website there is a user guide, which makes it much easier to start working with the module.
WisBlock series modules produced by Rak Wireless. They allow to make extended IoT projects, which can be used in advanced scenarios and in basic projects. WisBlock system includes: WisBlock Base Board, WisBlock Core developer module, WisBlock Sensors and WisBlock IO expansion modules. They are used for rapid deployment of engineering prototypes, and are also designed to create massive applications ready for industrial deployment.
The module pinouts are screw connectors. The pins used to connect the RAK5802 to the Base Board are located on the underside of the module. For more information about mounting, please refer to the user guide, mounting mechanism tab. Pins mean:
