Using the MOSFET Power Switch Module (CE09733)

Support Product Questions
1

Hello. I’m aiming to use this module to control a LED module with a RPi Pico. The LED module draws 700mA at 24VDC. I’m a bit confused by the product diagram though (below). For low-side switching I would have thought the load’s ground would go to the input of the MOSFET module, and the output of the MOSFET module would go to ground. But the diagram shows + and - for both load and supply. Could someone please point me to an example of connecting this module?

Hi Daryl.
Welcome
What a way to start. That is one of the worst product descriptions I have seen.
I for one would like to see a schematic before I commented.
I think someone reversed engineered this thing and published a schematic somewhere on the Forum but I don’t remember the circumstances now.
Cheers Bob

Thanks Bob. I worked out where I went wrong; I had incorrectly connected both the load -ve and supply -ve to ground, so the lamp was always on. All good now.
