SK108, SK109, and SK509 are industrial-grade remote four-channel wireless switch control modules, which provide four-channel signal input and four-channel control output interface. It has the characteristics of a simple interface and reliable work. Users can also configure and modify relevant parameters inside the module wirelessly in conjunction with the friendly PC interface.
The difference between wireless switch modules SK108, SK109, SK509
The parameters of the SK108, SK109, and SK509 switch modules are the same in transmitting current, receiving sensitivity, channel, modulation mode, and volume.
Which is better, SK108, SK109, SK509, how to choose the right wireless switch module?
The wireless switch module developed and produced by Shenzhen NiceRF Wireless Technology Co., Ltd. complies with the standard in terms of module quality and craftsmanship, so there is no need to worry about product quality. You can choose the appropriate switch module from your actual project, and you can consider the transmission distance, power, and cost budget of the project.
