Friday New Product: FETs
Solar botics
July 11, 2014
What we have today are not Fairly Expensive Tortillas or Fortunately Edible Theremins, but Field-Effect Transistors. If you know what it is, I will leave you to explore:

NDP6020P P-Channel FET, --2.5V gate, -20V, 24A max $1.95 An N-channel FET with an extremely low gate voltage which can be controlled by most 3.3V and 5V microcontrollers. |
..and no, these are not even Forcibly Eccentric Tabbies.
