MAX4466:
Description:
Add an ear to your project with this well-designed electret microphone amplifier. This fully assembled andtested board comes with a 20-20KHz electret microphone soldered on. For the amplification, we use theMaxim MAX4466, an op-amp specifically designed for this delicate task! The amplifier has excellent powersupply noise rejection, so this amplifier sounds really good and isn't nearly as noisy or scratchy as othermic amp breakouts we've tried!This breakout is best used for projects such as voice changers, audio recordingmpling, and audio-reactive projects that use FFT. On the back, we include a small trimmer pot to adjust the gain. You canset the gain from 25x to 125x. That's down to be about 200mVpp (for normal speaking volume about 6"away) which is good for attaching to something that expects 'line level' input without clipping, or up toabout 1Vpp, ideal for reading from a microcontroller ADC. The output is rail-to-rail so if the sounds getsloud, the output can go up to 5Vpp!
Using it is simple:
Connect GND to ground, VCC to 2.4-5VDC.For the best performance, use the "quietest" supply available (on an for Arduino, this would be the 3.3V supply).The audio waveform will come out of the OUT pin. The output will have a DC bias of VCC/2 so when itsperfectly quiet, the voltage will be a steady VCC/2 volts (it is DC coupled). If the audio equipment you're usingrequires AC coupled audio, place a 100uF capacitor between the output pin and the input of your device. Ifyou're connecting to an audio amplifier that has differential inputs orincludes decoupling capacitors, the100uF cap is not required.The output pin is not designed to drive speakers or anything but the smallest in-ear headphones- you'll needan audio amplifier (such as 3.7W stereo amp) if you want to connect the amp directly to speakers. If you'reconnecting to a microcontroller pin, you don't need an amplifier or decoupling capacitor - connect the OUTpin directly to the microcontroller ADC pin.For audio-reactive projects, we suggest using an FFT driver library which can take the audio input and 'translate' it into frequencies.

Product Description
This fully-featured UDA1334A I2S Stereo DAC breakout is a perfect match for any I2S-output audio interface. 3.3V - 5V logic levels (a rarity), and can process multiple different formats by setting two pins to high or low. The DAC will process data immediately, and give you a clear, analog, stereo line level output. It's even cool with MCLK-less I2S interfaces such as the Raspberry Pi (which it's ideal for) - a built in PLL will generate the proper clock from the incoming signal. For inputs, you can use classic I2S (the default) or 16-bit, 20-bit or 24-bit left justified data. You can set it up to take an input system/master clock but we default-set it to just generate it for you, so you only need to connect Data In, Word Select (Left/Right Clock) and Bit Clock lines. If you want, there's a mute pin and a de-emphasis filter you can turn on.

Description
This is a breakout board for the very handy 16-Channel Analog/Digital Multiplexer/Demultiplexer CD74HC4067.
This chip is like a rotary switch - it internally routes the common pin
(COM in the schematic, SIG on the board)to one of 16 channel pins (CHANxx).
It works with both digital and analog signals (the voltage can't be higher than VCC),
and the connections function in either direction.
To control it, connect 4 digital outputs to the chip's address select pins (S0-S3),
and send it the binary address of the channel you want (see the datasheet for details).
This allows you to connect up to 16 sensors to your system using only 5 pins!
Since the mux/demux also works with digital signals,
you can use it to pipe TTL-level serial data to or from multiple devices.
For example, you could use it to connect the TX pins of 16 devices to one RX pin on your microcontroller.
You can then select any one of those 16 devices to listen to.
If you want two-way communications, you can add a second board to route
your microcontroller's TX line to 16 device's RX lines.
By using multiple boards, you can create similar arrangements for I2C, SPI, etc.
The internal switches are bidirectional, support voltages between ground and VCC,
have low on resistance and low off leakage, and to prevent crosstalk, perform break-before-make switching.
The board also breaks out the chip's enable pin, which when driven high,
will completely disconnect the common pin (all switches off).

Resolution: 500dpi
Supply current: <60mA
Supply voltage: 3.3V
Fingerprint image entry time: <1.0 seconds
Peak current: <60mA
Window area: 15.3x18.2MM
Communication Interface: USB/UART

How the Module Works
1. Fingerprint features
The fingerprint algorithm extracts features from the acquired fingerprint image and represents the fingerprint information. The storage, comparison and search of fingerprints are all done by operating fingerprint features.
2. Fingerprint processing includes two processes: fingerprint registration process and fingerprint matching process (in which fingerprint matching is divided into fingerprint comparison (1:1) and fingerprint search (1:N) two ways).

When the fingerprint is registered, two fingerprints are entered for each fingerprint, and the input image is processed twice. The synthesis module is stored in the module.
When the fingerprint is matched, the fingerprint sensor is used to input the fingerprint image to be verified and processed, and then it is compared with the fingerprint module in the module (if it is matched with a module specified in the module, it is called fingerprint comparison mode, ie, 1:1 mode. If matching with multiple modules is called fingerprint search, ie 1:N mode, the module gives the matching result (pass or fail).

Feature:
MOSFET is an electronic devices with good switching characteristics. It is widely used in circuits, such as power supplies switching , motor drives, lighting dimmer and so on. Relay is another kind of module with switching characteristics. We designed a 4-channel MOSFET switch. It can supply up to four groups of electronic switches to control different circuit blocks respectively. Limited by the working priciples, MOSFET can only be used to control the DC circuit, such as DC-LED screen and so on, but not suitable for AC circuit control. In some extreme cases, it can be used to control 100V/33A DC circuit. However, it is suggested that the controlled DC voltage is more than 9V.
