Potentiometer
$2.18A potentiometer is a manually adjustable variable resistor with 3 terminals. Two of the terminals are connected to the opposite ends of a resistive element, and the third terminal connects to a sliding contact, called a wiper, moving over the resistive element. The potentiometer essentially functions as a variable resistance divider. The resistive element can be seen as two resistors in series (the total potentiometer resistance), where the wiper position determines the resistance ratio of the first resistor to the second resistor. If a reference voltage is applied across the end terminals, the position of the wiper determines the output voltage of the potentiometer.

Raspberry Pi 4 Aluminum Heatsink Case
$16.35It is not an enclosure or case, it should be called heatsink because the case itself is CNC aluminum and comes with thermal paste/tape to effectively dissipate heat generated from the processor, RAM IC. Furthermore, it is also integrated with two cooling fans (assembled, but not fasten to the case), just connect the power to run it. Please note that its Just the casing only (Without Raspberry Pi) The heatsink is only for Raspberry Pi 4 usage.
