    3 679,00 Ft
    Product introduction: The INMP441 is a high performance, low power, digital output, omnidirectional MEMS microphone with bottom port. The The complete INMP441 solution consists of a MEMS sensor, signal conditioning, analog to digital converter, anti-aliasing filter, power management and industry standard 24-bit I2S interface. The I2S interface allows the INMP441 to be directly connected to digital processors such as DSPs and microcontrollers without the need for an audio codec for use in the system. The INMP441 has a high signal-to-noise ratio and is an excellent choice for near field applications. The INMP441 has a flat wideband frequency response that results in high definition of natural sound. Product Features: 1. Digital I2S interface with high precision 24-bit data 2. High signal to noise ratio is 61 dBA 3. High sensitivity - 26 dBFS 4. Stable frequency response from 60 Hz to 15 kHz 5. Low power consumption: low current consumption 1.4 mA 6. High PSR: -75 dBFS Interface definition: SCK: Serial data clock for I2S interface WS: Serial data word selection for I2S interface L/R: Left/Right channel selection. When set to low, the microphone outputs a signal on the left channel of the I2S frame. When set to high level, the microphone outputs signals on the right channel SD: Serial data output of the I2S interface. VCC: Input power, 1.8V to 3.3V. GND: power ground This product provides tutorials for using ESP32 modules with I2S functionality. Connect to ESP32: INMP441 ESP32 SCK >> GPIO14 SD >> GPIO32 WS >> GPIO15 L/R >> GND GND >> GND VDD >> VDD3.3 What is the difference between an omnidirectional microphone and a unidirectional microphone: First of all, I understand that the sound divergence is all-round. One person speaks and diverge in the air. As for how far it can pass, it depends on many factors. 1.directional microphone, the general pickup radius is very small, 30 cm is a big one, single use, put it on the mouth, the sound quality is very good, because it is not picked up again. The shape is generally goose neck wheat, a rod, a curved rod, to your mouth, directivity, just listen to your voice. With a single-point microphone, the sensitivity is limited to a certain range. Sensitivity is too high, causing sharp whistling, etc., involving many other devices As for why not make a big pickup radius, there is a reason. Later 2.omnidirectional microphone, the general pickup radius is very large, one meter two meters three meters five meters have, compared with ten centimeters, this level is very different, it is not just picking a person's voice, but Multiple people, five six, seven eight or even ten. Omnidirectional microphones are highly sensitive, The omnidirectional microphone pickup radius is too large, and it will also pick up more ambient noise, so the sound quality is not as good as the single-point microphone, unless you do a good noise reduction. There is definitely a difference between collective use and single-person service. But omnidirectional wheat has a benefit, the wiring is simple, not one by one. Suitable for small meetings, ad hoc meetings, some remote discussions, remote operations. 3.single-point wheat generally supports local amplification, Omnidirectional microphones generally do not support local amplification. It should be noted that because of such high sensitivity, the local amplification whistling is very scary, and the current technology is difficult to deal with.

  • DC 3V-5V CJMCU-5351 Si5351A Si5351 I2C óragenerátor Breakout Board modul jelgenerátor óra 8KHz-160MHz Arduino számára

    1 294,00 Ft
     
    Never hunt around for another crystal again, with the Si5351A clock generator breakout ! This chip has a precision 25MHz crystal reference and internal PLL and dividers so it can generate just about any frequency, from <8KHz up to 150 MHz.
    The Si5351A clock generator is an I2C controller clock generator. It uses the onboard precision clock to drive multiple PLL's and clock dividers using I2C instructions. By setting up the PLL and dividers you can create precise and arbitrary frequencies. There are three independent outputs, and each one can have a different frequency. Outputs are 3Vpp, either through a breadboard-friendly header or, for RF work, an optional SMA connector.
    We put this handy little chip onto it's own breakout board PCB, with a 3.3V LDO regulator so it can be powered from 3-5VDC. We also put level shifting circuitry on the I2C lines so you can use this chip safely with 3V or 5V logic.
    Best of all, we even have a great tutorial and library to get you started! Our code is designed for use with the Arduino microcontroller and IDE but is easily ported to your favorite platform with I2C support

    Description:
    Want to make a hexapod walker? Maybe you're making a piece of art with tons of moving parts, or you need to drive a ton of LEDs with precise PWM output. Your microcontroller has a limited number of PWM outputs, and you find yourself running out! Not with the Adafruit 16-Channel 12-bit PWM/Servo Driver - I2C interface. With this pwm and servo driver breakout, you can control 16 free-running PWM outputs with just two pins! Need to run more than 16 PWM outputs? No problem. Chain together up to 62 of these beauties for up to an outstanding 992 PWM outputs.
    Features:
    Dimensions (no headers or terminal block) 2.5" x 1" x 0.1" (62.5mm x 25.4mm x 3mm)
    Weight (no headers or terminal block): 5.5grams
    Weight (with 3x4 headers & terminal block): 9grams
    This board/chip uses I2C 7-bit address between 0x60-0x80, selectable with jumpers
    Terminal block for power input (or you can use the 0.1" breakouts on the side)
    Reverse polarity protection on the terminal block input
    Green power-good LED
    3 pin connectors in groups of 4 so you can plug in 16 servos at once (Servo plugs are slightly wider than 0.1" so you can only stack 4 next to each other on 0.1" header
    "Chain-able" design
    A spot to place a big capacitor on the V line (in case you need it)
    220 ohm series resistors on all the output lines to protect them, and to make driving LEDs trivial
    Solder jumpers for the 6 address select pins
    i2c-controlled PWM driver with a built in clock. Unlike the TLC5940 family, you do not need to continuously send it signal tying up your microcontroller, its completely free running!
    It is 5V compliant, which means you can control it from a 3.3V microcontroller and still safely drive up to 6V outputs (this is good for when you want to control white or blue LEDs with 3.4 forward voltages)
    6 address select pins so you can wire up to 62 of these on a single i2c bus, a total of 992 outputs - that's a lot of servos or LEDs
    Adjustable frequency PWM up to about 1.6 KHz
    12-bit resolution for each output - for servos, that means about 4us resolution at 60Hz update rate
    Configurable push-pull or open-drain output
    Output enable pin to quickly disable all the outputs
    (1)Drive board connected to Arduino:
    The PWM driver board uses the I2C method, so only four lines can be connected to the Arduino device:
    "Classic" Arduino pin mode:
    5v -> VCC
    GND -> GND
    Analog 4 -> SDA
    Analog 5 -> SCL
    Old Mega pin way:
    5v -> VCC
    GND -> GND
    Digital 20 -> SDA
    Digital 21 -> SCL
    R3 and later Arduino pin method (Uno, Mega &
    Leonardo):
    (These boards have dedicated SDA and SCL pins)
    5v -> VCC
    GND -> GND
    SDA -> SDA
    SCL -> SCL
    VCC pin is only for the chip power supply, if you want to connect the servo or LED lights, use the V pin power supply, V pin supports 3.3 ~ 6V power supply (chip safe voltage 5V). It is recommended to connect the external power supply via the power supply terminal.
    (2) power supply part:
    Most of the servo design voltage is 5 ~ 6V, especially in a number of steering gear at the same time running, with the need for high-power power supply. If you are directly using the Arduino 5V pin to power the servo directly, there are some unpredictable problems, so we recommend that you have a suitable external power supply for the drive board.
    (3) Connect the servo:
    Most servos are connected using standard 3-wire female plugs, as long as the corresponding pin into the driver board on it. (Ground wire is generally black or brown, the signal line is generally yellow or white)
    (4) for the driver board assigned address:
    Each drive board of the cascade needs to have a unique access address. The initial I2C address of each driver board is 0 × 40, you can modify the upper right corner of the jumper I2C address. Connect a jumper with solder to indicate a binary number "1".
