{"product_id":"ht0740-breakout","title":"HT0740 40V \/ 10A Switch Breakout","description":"\u003cp\u003eOh boy, this is a Big. Damn. Switch. Program it to switch loads up to 40V \/ 10A connected to the HT0740 breakout's sturdy screw terminals, and use up to four breakouts at the same time using the configurable I2C addresses. Great for home automation.\u003c\/p\u003e\n\u003cp\u003eThis fully-isolated, I2C-controllable switch can switch big loads up to 40V at 10A. There are sturdy screw terminals to connect your switched load to, and a handy little white status LED to give you visual feedback. Because we've used an I2C expander, you can use up to four of these at once, by configuring the addresses with the cuttable traces on the back of the board.\u003c\/p\u003e\n\u003cp\u003eThe HT0740 breakout has an I2C interface and is 3.3V or 5V compatible.
