It is an RM065 500 Ohm Trimpot Trimmer Potentiometer.  The potentiometer is easy to mount on a PCB and can be adjusted using a screwdriver.

0402 capacitor is Mounted either by flow or reflow soldering methods and gives excellent dielectric strength due to uniform structure of dielectric layers 

Small Size and light weight resistor which is suitable for both wave and reflow soldering leading to reduction in production costs.

AMS1117-2.5V, 1A, Voltage Regulator IC is a series of low dropout three -terminal regulators with a dropout of 2.5V at 1A load current. AMS 1117 features a very low standby current 2mA.

AMS 1117 offers thermal shut down and current limit functions, to assure the stability of chip and power system. And it uses a trimming technique to guarantee output voltage accuracy within 2%. Other output voltage accuracy can be customized on demand, such as 1%

A crystal oscillator is an electronic circuit or device which is used to generate a stable frequency with the help of a crystal instead of a tuned circuit. The crystal when vibrates, it acts like a resonator & as a result generates an oscillated frequency. The resonator circuit uses a crystal to generate the oscillation.

A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.

These resistors are typical axial-lead metal film resistors, which have much better temperature stability than their carbon equivalents which provides lower noise and are generally better for high frequency or radio frequency applications.

It is an RM065 2K Ohm Trimpot Trimmer Potentiometer.  The potentiometer is easy to mount on a PCB and can be adjusted using a screwdriver.

A ceramic capacitor is a fixed-value capacitor where the ceramic material acts as the dielectric. It is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes. The composition of the ceramic material defines the electrical behavior and therefore applications.
