ARDUINO RFLINK-Mix Wireless UART to IO Module
RFLINK-Mix Wireless UART-to-IO is an easy-to-use module that allows users to quickly set up remote IO devices. You don’t need to set up many long cables as the general wired IO suite do, you only need to connect the UART ROOT board of RFLINL-Mix to the master board (Arduino, Raspberry Pi, any other HOST), and the IO device board of RFLINK-Mix to the IO devices, then a wireless IO system is ready to go. Each IO device board has 3 sets of IO port , thus an 1-to-4 RFLINK-Mix UART to IO suite can control 12 sets of IO port.
Module appearance and dimension
The RFLINK-Mix UART-to-IO module contains a piece of the UART ROOT end (left). Up to four IO Devices (right side of the figure below, numbered 0 to 3), both Although the appearance is the same, it can be identified by the label on the back of the ROOT or DEVICE Check the box to identify.
As shown in the figure below, the leftmost figure is the part side, and the others are the label side The Group Address of this group of RFLINK-UARTROOT modules is 0001, Baud rate 19200. RFLINK I2C Devices as Device 0 , Device 1,Device 2, Device 3, Group Address is 0003
