USB Relay controllers were one the most popular products we ever carried. These boards with built in USB based command line mode, make it easy for everyone to control the relays without even writing a single line of code. There were a lot of customers who were asking Ethernet and wireless version of these modules, so a few weeks ago we started working on the wireless relay module with eight relays, fully isolated with opto couplers and USB. This board can be connected to a PC through USB and can be used just like an 8 Channel USB Relay Module. The onboard radio allows the user to remove the USB and connect an RF dongle and move the board anywhere within 500 ft range. Over the wireless, the command line interface will be exactly the same as USB interface. So there is no need of modifying existing application which were written for USB based modules. Here is a screenshot of the 8 Channel Wireless Relay Controller Design in KiCad.

Update: We have received the boards from our PCB house. Those boards were assembled and basic functionality is tested. A photo of the assembled unit is below.

We have posted initial design here.
