The IRFI740G is an N-Channel MOSFET from International Rectifier. It has maximum VDSS rated at 10V and can handle continuous drain current up to 5.4A at 150C. The IRFI740G is a 400V 5.4A 40W TO220F Plastic Package 3Pins Power MOSFET.
The 74HC86D, 7486D, HC86D are contain four independent 2-input exclusive-OR gates. They perform the Boolean function Y = A B or Y = AB + A(B) in positive logic. A common application is as a true/complement element.
The ENC28J60-I/SO is a standalone Ethernet controller with an industry standard Serial Peripheral Interface (SPI™). It is designed to serve as an Ethernet network interface for any microcontroller equipped with SPI Communication.
The HW-040 Rotary Encoder Module is a device that generates an electrical signal based on how much the rotary input device (knob) is rotated and the direction it is rotating
The TIP140, TIP141 and TIP142 are 100V 10A 125W Silicon Epitaxial-Base NPN power transistors in monolithic Darlington configuration, mounted in TO-220A/B Package.
