The HT0740 40V / 10A Switch Breakout is a fully-isolated, I2C-controllable switch that can switch big loads up to 40 V at 10 A

There are sturdy screw terminals to connect your switched load to, and a handy little white status LED to give you visual feedback. Because an I2C expander has been used, you can use up to four of these at once, by configuring the addresses with the cuttable traces on the back of the board.
