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.

Round artist/painting brush for all kinds of paints & colours.

WeMos- D1 R2 WiFi ESP8266 Development Board is programmable via Arduino IDE. This is an ESP8266 based WiFi enabled microprocessor unit on a Arduino-UNO footprint. That means the board looks and works (in most cases) like an UNO. Several shields, sensors and output devices that are manufactured for the Arduino platform will work on the WeMos-D1R2 with the added advantage of builtin WiFi.

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.
