From the project
Logic-level N-channel and P-channel MOSFET modules for education, breadboarding, and prototyping.
SBK_FET1 is a compact educational MOSFET module designed for breadboards, prototyping, and learning electronic switching circuits.
The module is available in both N-channel and P-channel versions and provides clearly labeled Drain, Gate, and Source connections. An optional output voltage indicator LED can be enabled by connecting the GND pin or disabled by leaving it unconnected.
