    Parts can have many statuses as they progress through the configuration, analysis, review, and approval stages.

    Active
  • Moisture Sensitivity Level (MSL)

    Moisture Sensitivity Level (MSL) is a standardized rating that indicates the susceptibility of electronic components, particularly semiconductors, to moisture-induced damage during storage and the soldering process, defining the allowable exposure time to ambient conditions before they require special handling or baking to prevent failures

    Not Applicable
  • Voltage - Supply

    Voltage - Supply refers to the range of voltage levels that an electronic component or circuit is designed to operate with. It indicates the minimum and maximum supply voltage that can be applied for the device to function properly. Providing supply voltages outside this range can lead to malfunction, damage, or reduced performance. This parameter is critical for ensuring compatibility between different components in a circuit.

    3V~3.6V
  • Frequency

    In electronic components, the parameter "Frequency" refers to the rate at which a signal oscillates or cycles within a given period of time. It is typically measured in Hertz (Hz) and represents how many times a signal completes a full cycle in one second. Frequency is a crucial aspect in electronic components as it determines the behavior and performance of various devices such as oscillators, filters, and communication systems. Understanding the frequency characteristics of components is essential for designing and analyzing electronic circuits to ensure proper functionality and compatibility with other components in a system.

    2.412GHz~2.484GHz
  • Data Rate

    Data Rate is defined as the amount of data transmitted during a specified time period over a network. It is the speed at which data is transferred from one device to another or between a peripheral device and the computer. It is generally measured in Mega bits per second(Mbps) or Mega bytes per second(MBps).

    54Mbps
  • Protocol

    In electronic components, the parameter "Protocol" refers to a set of rules and standards that govern the communication between devices. It defines the format, timing, sequencing, and error checking methods for data exchange between different components or systems. Protocols ensure that devices can understand and interpret data correctly, enabling them to communicate effectively with each other. Common examples of protocols in electronics include USB, Ethernet, SPI, I2C, and Bluetooth, each with its own specifications for data transmission. Understanding and adhering to protocols is essential for ensuring compatibility and reliable communication between electronic devices.

  • Power - Output

    Power Output in electronic components refers to the amount of electrical power that a device can deliver to a load. It is typically measured in watts and indicates the effectiveness of the component in converting electrical energy into usable work or signal. Power Output can vary based on the component's design, operating conditions, and intended application, making it a critical factor in the performance of amplifiers, power supplies, and other electronic devices. Understanding the Power Output helps in selecting appropriate components for specific applications to ensure efficiency and reliability.

  • Antenna Type

    There are several different types of antennas in three broad categories: omni-directional, directional, and semi-directional.

    PCB Trace
  • Sensitivity

    Sensitivity in electronic components refers to the degree to which the output of a device responds to changes in input. It indicates how effectively a component translates a specific input signal into an observable output. High sensitivity means that even small variations in input can produce significant changes in output, making the device more responsive to signals. Sensitivity is crucial in applications where precise measurements or signal detection are required.

    -90dBm
  • Serial Interfaces

    A serial interface is a communication interface between two digital systems that transmits data as a series of voltage pulses down a wire. Essentially, the serial interface encodes the bits of a binary number by their "temporal" location on a wire rather than their "spatial" location within a set of wires.

    ADC, I2C, PWM, SPI, UART
  • Current - Transmitting

    Current - Transmitting is a parameter used to describe the maximum amount of electrical current that an electronic component can handle while in the transmitting mode. This parameter is crucial for components such as transistors, diodes, and integrated circuits that are involved in transmitting signals or power within a circuit. Exceeding the specified current transmitting rating can lead to overheating, component failure, or even damage to the entire circuit. Designers and engineers must carefully consider this parameter when selecting components to ensure the reliability and performance of the electronic system.

    11.1mA
  • Modulation

    In electronic components, modulation refers to the process of varying one or more properties of a periodic waveform, known as the carrier signal, in order to encode information. This modulation technique is commonly used in communication systems to transmit data efficiently over long distances. By modulating the carrier signal, information such as audio, video, or data can be embedded onto the signal for transmission and then demodulated at the receiving end to retrieve the original information. There are various types of modulation techniques, including amplitude modulation (AM), frequency modulation (FM), and phase modulation (PM), each with its own advantages and applications in different communication systems.

ESP-12E Circuit

Normally, to program the ESP8266-12E, you have to connect certain pins to each other, and to ground and VCC, and a few of the GPIO pins need to be connected correctly. You then connect the TX and RX pins to your USB-to-serial adapters like the FTDI or CP2102 or similar boards.


ESP-12E vs. ESP32

Both chips have a 32-bit processor. The ESP32 is a dual-core 160MHz to 240MHz CPU, whereas the ESP-12E is a single-core processor that runs at 80MHz.
