  2. ESP32 - Wikipedia

    en.wikipedia.org/wiki/ESP32

    ESP32 is a series of low-cost, low-power system-on-chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth.The ESP32 series employs either a Tensilica Xtensa LX6 microprocessor in both dual-core and single-core variations, an Xtensa LX7 dual-core microprocessor, or a single-core RISC-V microprocessor and includes built-in antenna switches, RF balun, power amplifier, low-noise ...

  3. Jumper (computing) - Wikipedia

    en.wikipedia.org/wiki/Jumper_(computing)

    Jumper pins (points to be connected by the jumper) are arranged in groups called jumper blocks, each group having at least one pair of contact points.An appropriately sized conductive sleeve itself called a jumper, or more technically, a shunt jumper, is slipped over the pins to complete the circuit.

  4. NodeMCU - Wikipedia

    Plastic leaded chip carrier (PLCC): square, J-lead, pin spacing 1.27 mm; Quad flat package : various sizes, with pins on all four sides; Low-profile quad flat-package : 1.4 mm high, varying sized and pins on all four sides; Plastic quad flat-pack , a square with pins on all four sides, 44 or more pins

  6. CPU socket - Wikipedia

    en.wikipedia.org/wiki/CPU_socket

    For chips with many pins, zero insertion force (ZIF) sockets are preferred. Common sockets include pin grid array (PGA) or land grid array (LGA) . These designs apply a compression force once either a handle (PGA type) or a surface plate (LGA type) is put into place.

  7. Arduino Nano - Wikipedia

    The following table compares official Arduino boards, and has a similar layout as a table in the Arduino Uno article. The table is split with dark bars into three high-level microcontroller groups: 8-bit AVR cores, 32-bit ARM Cortex-M cores, and 32-bit ESP32 microcontrollers.

  8. JTAG - Wikipedia

    en.wikipedia.org/wiki/JTAG

    JTAG (named after the Joint Test Action Group which codified it) is an industry standard for verifying designs of and testing printed circuit boards after manufacture.. JTAG implements standards for on-chip instrumentation in electronic design automation (EDA) as a complementary tool to digital simulation. [1]

  9. Pull-up resistor - Wikipedia

    en.wikipedia.org/wiki/Pull-up_resistor

    A pull-up resistor may be used when interfacing logic gates to inputs. For example, an input signal may be pulled by a resistor, then a switch or jumper strap can be used to connect that input to ground. This can be used for configuration information, to select options or for troubleshooting of a device.
