Product description: RS485 module - WisBlock IO extension - Rak Wireless RAK5802
RAK5802extension is a converter of standard RS485 interface to a serial port. It hasESD 18 kVprotection and low power consumption. It supports up to 16 RS485 nodes, automatically detectsTX / RXsignals. It is compatible with many WisBlock modules, it needs connection to WisBlockBase Boardand WisBlockCoredevelopment modules to work properly.
On manufacturer website there is auser guide, which makes it much easier to start working with the module.
WisBlockseries modules produced byRak Wireless. They allow to makeextended IoT projects, which can be used in advanced scenarios and in basic projects. WisBlock system includes: WisBlockBase Board, WisBlockCoredeveloper module, WisBlockSensorsand WisBlockIO expansionmodules. They are used for rapid deployment of engineering prototypes, and are also designed to create massive applications ready for industrial deployment.
