  2. Reference designator - Wikipedia

    en.wikipedia.org/wiki/Reference_designator

    The reference designator usually consists of one or two letters followed by a number, e.g. C3, D1, R4, U15. The number is sometimes followed by a letter, indicating that components are grouped or matched with each other, e.g. R17A, R17B. The IEEE 315 standard contains a list of Class Designation Letters to use for electrical and electronic ...

  3. Electronic symbol - Wikipedia

    en.wikipedia.org/wiki/Electronic_symbol

    Common circuit diagram symbols (US ANSI symbols) An electronic symbol is a pictogram used to represent various electrical and electronic devices or functions, such as wires, batteries, resistors, and transistors, in a schematic diagram of an electrical or electronic circuit. These symbols are largely standardized internationally today, but may ...

  4. Circuit diagram - Wikipedia

    en.wikipedia.org/wiki/Circuit_diagram

    A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.

  6. STM32 - Wikipedia

    en.wikipedia.org/wiki/STM32

    All STM32 microcontrollers have a ROM'ed bootloader that supports loading a binary image into its flash memory using one or more peripherals (varies by STM32 family). Since all STM32 bootloaders support loading from the USART peripheral and most boards connect the USART to RS-232 or a USB -to- UART adapter IC, thus it's a universal method to ...

  7. Wiring diagram - Wikipedia

    en.wikipedia.org/wiki/Wiring_diagram

    An automotive wiring diagram, showing useful information such as crimp connection locations and wire colors. These details may not be so easily found on a more schematic drawing. A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the ...

    Some common pinouts [20] for 2.54 mm (0.100 in) pin headers are: ARM 2×10 pin (or sometimes the older 2×7), used by almost all ARM-based systems; MIPS EJTAG (2×7 pin) used for MIPS based systems; 2×5 pin Altera ByteBlaster-compatible JTAG extended by multiple vendors; 2×5 pin AVR extends Altera JTAG with SRST (and in some cases TRST and an ...

  9. Schematic editor - Wikipedia

    en.wikipedia.org/wiki/Schematic_editor

    A schematic editor is a tool for schematic capture of electrical circuits or electronic circuits.. Schematic editors replaced manual drawing of schematic diagrams, but they still retain the capability of outputting schematics on specially formatted sheets.
