Saw this new product and went “wow - just what I need”. But came back to earth and realized there might be complications.
My concern is: This timer has a max VDD of 5.5v. My current project - 7.5v. I see a p-channel mosfet in the drawings but am not 100% certain that I can use it to switch the 7.5v.
Could someone kindly confirm that I can use the mosfet for this purpose, and if so, then a couple of hints as how to use it.
Many thanks, and - I will be out of town and away from internet for (gasp!) almost 3 weeks, so will not be able to respond to questions until early July.
Hi Alan.
No, the maximum voltage the board can handle is 5.5 volts. You could use the board to switch a second MOSFET that could take 7.5 volts though. Our [MOSFET Power Control Kit could be used for that.
The Nano Power Timer would switch the MOSFET power control kit and the power control kit would then switch your 7.5 volt power source. You’d still need a lower voltage supply for the power timer though.](SparkFun MOSFET Power Control Kit - COM-12959 - SparkFun Electronics)
That sounds like it should work. Presumably both the timer and the second mosfet and my project will share a common ground.
I do love mosfets…
Thanks!
