A tag is a keyword or label that categorizes your question with other, similar questions. Using the right tags makes it easier for others to find and answer your question.

A device which includes a central processing unit (CPU), memory, and (generally) an assortment of I/O peripherals (UART, ADC, DAC, general-purpose I/O, I2C, etc.) in a tightly-coupled standalone packa…
Be sure to use the Arduino Stack Exchange for questions that are more Arduino and less electronics.
An electronic device which supplies electrical energy to a load. Can be AC or DC input. Typically DC output.

Questions relating to the construction and applications of operational amplifiers,
a semiconductor device that can amplify signals and switch power. Most used types are bipolar (BJT, for Bipolar Junction Transistor), UJT (Unijunction transistor) and MOSFET (FET, fo…
a primary concern for the design under discussion. Use the "low-power" tag when that applies.
a light-emitting diode. Lighting an LED is considered the "Hello world" of a circuit design, and it can be as simple as putting a series resistor or can get more complicated, involving PWM a…

the acronym to Printed Circuit Board. A PCB is a carrier for the circuit's components and their electrical connections.
Flow of electric charge - typically movement of charge carriers, such as electrons. Measured in amperes (A).
adapt the range of the signal to a requirement, to make it more robust for transmission, or to satisfy interface requirement (like input/output impedance)
Digital electronics treats discrete signals, unlike analog electronics that treat continuous signals. Digital logic is used to perform arithmetic operations with electric signals, and constitutes the …
A resistor obeys Ohm's law (V=IR); the current through it is equal to the voltage across it divided by the resistance (equivalently \$I=\frac{V}{R}\$)
Short for Radio-Frequency. Frequencies at which radiation (intentional or not) plays a role. Typically associated with wireless communications, but also relevant for high-speed PCB design.
About designing the boards which carry the components of an electronic circuit. For questions about getting them built instead use PCB-fabrication. If your question is specific to a certain CAD tool, …
Universal Serial Bus. If your question relates to a specific chip, please mention it in your question.
An electrical actuator that converts electrical energy into rotational motion or sustained linear motion (linear motor). There are many types of electric motors. If the specific type of motor is known…
semiconductor components made from a P-type and N-type silicon material, that allows current to only flow in one direction.
Devices to interrupt or route a signal or power one of several ways.
A transformer couples two or more AC signals through a magnetic field. Often used as galvanic isolation and to transform one AC voltage to another.
a brand of 8, 16, and 32 bit RISC microcontrollers manufactured by Microchip. "PIC" originally was an acronym for "Peripheral Interface Controller".
an analog circuit that produces a stable output voltage that doesn't vary with input voltage or load changes. Switching regulators are much more efficient than linear ones.
Sensors convert a physical quantity (e.g. temperature, pressure) into an electrical signal.
refers to alternating current mains power. It usually applies to voltages with >100V RMS, but can also be used for ex. 24V industrial AC power.
Questions about designing electronics for measuring, processing, and amplifying audio signals.
Analog circuits have a range of voltages, rather than just two as in digital logic.
a logic chip that is configured by the customer after manufacturing—hence "field-programmable".
a term to describe how a circuit should behaved based on accomplishing a particular task. When designing circuits, one should consider how it works, the target specifications, efficiency, cost effecti…
an electrically controlled switch. Electromechanical relays use an electromagnet to activate mechanical contacts, solid-state relays use semiconductor switches.
an electronic circuit built onto a single plate of a semiconductor material, normally silicon. Modern ICs may contain billions of transistors and they have played a major…
the third ARM family by STMicroelectronics. It follows their earlier STR9 family based on the ARM9E core, and STR7 family based on the ARM7TDMI core. The STM32 is based on the ARM Cortex-…
