1, 2 * 3 w miniature digital power amplifier board class D power supply can use the computer?
Answer: power amplifier board can use a computer power supply, but will produce noise may be produced (also some customers did not appear murmurs), the best advice of independent power supply.
2, miniature digital 2 * 3 w class D power amplifier boards with the speaker of the house is good?
Answer: our speaker is only provide DIY players try, sound is not particularly good, if the pursuit of high sound client can buy separately.
3, 2 * 3 w miniature digital power amplifier board class D why there are noise after power on the speaker?
The answer:
1, appear whistlers, should be the audio input line, the introduction of shielded wire should be used for audio input line, and then there is audio input line don't hung up to connect good audio source.
2, is a kind of reason may be that some power supply is bad interference is very big, switch power supply.

Description: This is the  RGB and Gesture Sensor, a small breakout board with a built in APDS-9960 sensor that offers ambient light and color measuring, proximity detection, and touchless gesture sensing. With this RGB and Gesture Sensor you will be able to control a computer, microcontroller, robot, and more with a simple swipe of your hand! This is, in fact, the same sensor that the Samsung Galaxy S5 uses and is probably one of the best gesture sensors on the market for the price.
The APDS-9960 is a serious little piece of hardware with built in UV and IR blocking filters, four separate diodes sensitive to different directions, and an I2C compatible interface. For your convenience we have broken out the following pins: VL (optional power to IR LED), GND (Ground), VCC (power to APDS-9960 sensor), SDA (I2C data), SCL (I2C clock), and INT (interrupt). Each APDS-9960 also has a detection range of 4 to 8 inches (10 to 20 cm).

The MH-ET LIVE Tiny88(16.0Mhz) based microcontroller development board similar  to the Arduino line, only cheaper, smaller, and a bit less powerful. With the ability to use the familiar  Arduino IDE the MH-ET LIVE Tiny88(16.0Mhz) is a great board to jump into electronics, or perfect for when an other board is too big or too much.The MH-ET LIVE Tiny88(16.0Mhz) is shipped fully assembled except for the headersincluded and easy to solder them by yourself.
Specs:
 
Support for the Arduino IDE 1.0 (OSX/Win/Linux)
1. Power via USB or External Source - 5v or 7-35v (12v or less recommended,
automatic selection)
2. On-board 500ma 5V Regulator
3. Built-in USB
4.  26 I/O Pins (2 are used for USB only if your program actively communicates over  USB, otherwise you can use all 6 even if you are programming via USB)
5. 8k Flash Memory (about 6k after bootloader)
6. I2C and SPI
7. 26-PWM (26 pins with Software PWM,only two(D9,D10) with hardware PWM )
8.  ADC on 8 pins
9.  Power LED and Test/Status LED
10. Size(mm):44.5x18.3x3

CJMCU-219 is a module with the I2C interface of zero drift and bi-directional current/power monitoring and control integrated circuit (IC), further expand the TI energy-saving electronic products.INA219 has the industry's highest precision and the small size, not only can monitor the pressure drop on the shunt resistor, sensing shunt power supply voltage, at the same time also can calculate the power.The device adopts the SOT23 packaging, but for the server, notebook computer, power supply, battery management and digital electric vehicle and telecommunication equipment measuring flu provide small, low cost solution.
 
INA219-40 c to 85 c temperature range and can realize the maximum error of 1% accuracy, maximum offset of 100 uV.The advantage of the high precision of the product in combination with 12 resolution, can help clients as much as possible, reduce the pressure drop on the shunt resistor, which can minimize the power loss and power consumption, and saving board space.The device epic of 26 bus voltage range of 0 V to 26 V.
 
INA219 other important features include:
Calibration programmable registers can directly read its unit of measure is the ampere current, and power in watts per read. For as many as 128 sampling averaging, in order to realize filter in noise environment. The I2C interface has a timeout, not only can avoid the bus lock, but also can provide high-speed mode, meet the communication requirements of up to 3.4 MHz. All features are support software programmable INA219. Using single power supply, the working voltage between 3.0 to 5.5 V.

MEGA2560 PRO
Embed version of Mega 2560 CH340G/ATmega2560 - compatible with Arduino Mega 2560 board. Built on the Atmel ATmega2560 microcontroller and USB-UART interface chip CH340G.
Board have compact size 38x55mm. It is good solution, to make your final project on solder proto-board.
Board for functionality similar to the Arduino Mega 2560. It is embed board, but the same stable, and uses the original chips ATmega2560 (16 MHz).
The board used the chip CH340G as converter UART-USB. When you work in the frequency 12Mhz, giving a stable result of data exchange (need install drivers to computer).
Mega PRO (Embed) 2560 CH340G / ATmega2560 - connects to the computer via microUSB cable (used for almost all Android smartphones).
You can supply power to board through the MicroUSB connector or to power pinheaders. The voltage regulator (LDO) can deal with incoming voltage from 6V to 9V (peack 18V) DC. Output current for 5V - about 800mA, for 3.3V - about 800mA (Please note that the higher the input voltage the lower the outgoing current). That will provide a reliable power most of your initial projects.
