Review on SMAKN® LCUS 1 Module Intelligent Control by Edgardo Ennis

Supplied in an outer sealed ziplock consumer bag and an inner silver ESD bag. The package contained a minidisk with drivers and software. The design dates back to 2013 and features a more reliable CH340 USB-to-serial converter chip because FTDI released drivers that blocked third-party clones of their chip. which makes the entire FTDI market suspicious. You never know if you have a "secure" USB-to-serial chip or you're just one step away from being bricked with the official FTDI driver due to a Windows driver update. Unfortunately, the instructions are in Chinese, some file names are also in Unicode, which is not displayed on many English operating systems. Today there are two microcircuits CH340 and CH341 (more advanced), they have several modes of operation, but this implementation is like a simple relay through a USB port, Windows installs the driver on XP, W7, W8, W10. and create a COM port that any terminal software can access and send commands to. The command lines are familiar and similar to the old modem commands. Which say on / off to throw the relay. Three ports: NC, C, NO for normally closed, common and normally open. Switching a switching relay with a command from software allows you to close or open a circuit using a relay and a switch. There are also programs for MSDOS, Linux and MacOSX that recognize a USB device as an HID and create a serial port that can be controlled with the same commands. so close to universal. They can be purchased for a lower price, but then you have to pay extra for shipping and find the software yourself online. which is not easy as it is scattered. It was a very convenient way to find a USB relay controller at a very low price with software. The current and voltage ratings are also fairly wide, 10A and 30VDC and up to 250VAC, but I'd be wary of upstream inductive feedback spikes if you're using it as a switch, the relay is housed in a small blue plastic block, you can't give off a lot of heat. and certainly not intrinsically safe. Ensure you fully understand the consequences of a high current interruption or arcing that can occur upstream when a high voltage circuit is disconnected. in other words. Don't use it to switch a horizontal flyback transformer and a Van de Graaff generator. or F.lux condenser!
