The STM8S103, R421A08, R221A04 and R413D08 are relay boards that are controlled from your computer, through the USB port. The relays allow you to control any 12 volt appliance such as led lights for example. If you wish to control mains 120/220 Volt appliances you can install an additional 120/220 volt relay that is 12 volt activated. The relay boards are the most common ones available online. They can also process input signals such as switches and sensors. RS485 modbus contains the source code to activate any of the relays on these boards. The project file is in C++ and is compiled with MS Visual studio. Windows 7/8 compatible.
