40V 10A HT0740 Switch Breakout I2C-controllable

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.

This 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.

The HT0740 breakout has an I2C interface and is 3.3V or 5V compatible.

• DC voltage only. Do not use to switch loads higher than 40V / 10A. Despite the MOSFET part being rated for higher voltages, the screw terminals are not suitable for this.
