MAX4466:
Description:
Add an ear to your project with this well-designed electret microphone amplifier. This fully assembled and tested board comes with a 20-20KHz electret microphone soldered on. For the amplification, we use the Maxim MAX4466, an op-amp specifically designed for this delicate task! The amplifier has excellent power supply noise rejection, so this amplifier sounds really good and isn't nearly as noisy or scratchy as other mic 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 can set 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 to about 1Vpp, ideal for reading from a microcontroller ADC. The output is rail-to-rail so if the sounds gets loud, 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 its perfectly quiet, the voltage will be a steady VCC/2 volts (it is DC coupled). If the audio equipment you're using requires AC coupled audio, place a 100uF capacitor between the output pin and the input of your device. If you're connecting to an audio amplifier that has differential inputs or includes decoupling capacitors, the 100uF cap is not required.The output pin is not designed to drive speakers or anything but the smallest in-ear headphones- you'll need an audio amplifier (such as 3.7W stereo amp) if you want to connect the amp directly to speakers. If you're connecting to a microcontroller pin, you don't need an amplifier or decoupling capacitor - connect the OUT pin 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 Introduction:
1.Operating Voltage: 5V
2.Pulse Number for One Circle: 20
3.Rotary encoder can count the output pulse times by rotating positively and negatively. This counting method has no limitation, it can reset and come back to the  initial status if matching with the key on the encoder (that is to say it will count from 0)
4.Operating Principle: Incremental encoder is a kind of rotary sensor which transforms the rotation displacement into a series of digital pulse signal. These pulses are used to control angular displacement. In Eltra encoder, the transformation of angular displacement adopts photoelectric scaning principle. The reading system is based on the radial dividing plate's rotation of alternative light window and non-light window, and it will be exposed to infrared light source at the same time. The light will reflect the picture of plate on the surface of receiver. The receiver is covered by a diffraction grating, and it has the same window width with the plate. The operation of receiver is to detect the change of light plate rotation, then transform the light change into electric change. Increase the low level signal into high level and generate square pulse without any interference. This process needs circuit to deal with. The reading system usually adopts differential method, that is compare two different signals who have the same waveform bu the phase difference is 180 degree so as to improve the output signal quality and stability. Reading is formed on the basis of the difference between two signals, so it eliminates the interference.

The VL53L0X from ST Microelectronics is a time-of-flight ranging system integrated into a compact module. This board is a carrier for the VL53L0X, so we recommend careful reading of the VL53L0X datasheet (1MB pdf) before using this product. 
The VL53L0 uses ST's FlightSense technology to precisely measure how long it takes for emitted pulses of infrared laser light to reach the nearest object and be reflected back to a detector, so it can be considered a tiny, self-contained lidar system. This time-of-flight (TOF) measurement enables it to accurately determine the absolute distance to a target without the object's reflectance greatly influencing the measurement. The sensor can report distances of up to 2 m (6.6 ft) with 1 mm resolution, but its effective range and accuracy (noise) depend heavily on ambient conditions and target characteristics like reflectance and size, as well as the sensor configuration. (The sensor's accuracy is specified to range from ±3% at best to over ±10% in less optimal conditions.) 
Ranging measurements are available through the sensor's I⊃2;C (TWI) interface, which is also used to configure sensor settings, and the sensor provides two additional pins: a shutdown input and an interrupt output. 
The VL53L0X is a great IC, but its small, leadless, LGA package makes it difficult for the typical student or hobbyist to use. It also operates at a recommended voltage of 2.8 V, which can make interfacing difficult for microcontrollers operating at 3.3 V or 5 V. Our breakout board addresses these issues, making it easier to get started using the sensor, while keeping the overall size as small as possible. 
  
PIN     Description 
VDD  Regulated 2.8 V output. Almost 150 mA is available to power external components. (If you want to bypass the internal regulator, you can instead use this pin as a 2.8 V input with VIN disconnected.)
 
VIN  This is the main 2.6 V to 5.5 V power supply connection. The SCL and SDA level shifters pull the I⊃2;C lines high to this level.
 
GND  The ground (0 V) connection for your power supply. Your I⊃2;C control source must also share a common ground with this board.
 
SDA    Level-shifted I⊃2;C data line: HIGH is VIN, LOW is 0 V
 
SCL      Level-shifted I⊃2;C clock line: HIGH is VIN, LOW is 0 V
 
XSHUT    This pin is an active-low shutdown input; the board pulls it up to VDD to enable the sensor by default. Driving this pin low puts the sensor into hardware standby. This input is not level-shifted.

 About Drv8825
 
Introduction:
 
The DRV8825 stepper motor driver carrier is a breakout board for TI’s DRV8825 microstepping bipolar stepper motor driver.
 
The module has a pinout and interface that are nearly identical to those of our A4988 stepper motor driver carriers, so it can be used as a higher-performance drop-in replacement for those boards in many applications.
 
The DRV8825 features adjustable current limiting, overcurrent and overtemperature protection, and six microstep resolutions (down to 1/32-step). It operates from 8.2 – 45 V and can deliver up to approximately 1.5 A per phase without a heat sink or forced air flow (rated for up to 2.2 A per coil with sufficient additional cooling).
 
Features:
 
Simple step and direction control interface
Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step
Can interface directly with 3.3 V and 5 V systems
Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout
Short-to-ground and shorted-load protection
4-layer, 2 oz copper PCB for improved heat dissipation
Exposed solderable ground pad below the driver IC on the bottom of the PCB
Module size, pinout, and interface match those of our A4988 stepper motor driver carriers in most respects (see the bottom of this page for more information)
Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates
Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)
45 V maximum supply voltage
Built-in regulator (no external logic voltage supply needed)

The power supply is a kind of high-efficiency voltage automatically regulator.
Whatever is the input voltage value,the output voltage can be maintained constant.
For example,set the output to 12V, then the variation of the input voltage in the range of 5-32V,
the output voltage in the 12V invariant.
This module has a perfect protection function, and can be widely used in notebook power,
vehicle power supply, solar charge etc..
Advantages:
The input uses replaceable fuse to protect power supply and equipment;
The whole electrolysis use patch, low resistance, high frequency capacitor
,to make the ripple down to the freezing point;
Constant voltage, constant current, under voltage protection (MPPT is more suitable for solar charging)
The output has error indicating lamp,it will light when the output voltage drift too serious,
short circuit and other fault;
Inductor use iron silicon aluminum, 0.8 double winding, generate less heat.
