Quick tips:

1. Please plug the power cord into the amp THEN the wall.

Some customers may see some slight sparks flying when they plug the power supply into the amplifier, because they use it in wrong way, you need to connect the amp to the power supply first, then plug the power supply into the 110v AC outlet, don't worry about the sparks, because this is class d amplifier, the capacitors need to charge when the power in, it's normal and safe.

2. The amp will off when you switch off, but it's normal that the power LED light stay on even switch off, the power LED light on means the power supply in.

3. You can pair with your Bluetooth device when the amp power on. But if Bluetooth connects, playback from the physical input is interrupted.

Kinter K2020A+ Limited Edition Original Tripath TA2020-020 Class-T Hi-Fi Audio Mini Amplifier with 12V 5A Power Supply Black

Model: K2020A+   |    Mpn: K2022A+   |    Ean: 0651814994414   |    PartNumber: K2022A+   |   Asin: B077Z7DBRT

REAL Tripath quality

Known for producing sound as warm and vibrant as tube amplifiers, Tripath amplifiers have earned a solid reputation for sound quality from budget-minded audiophiles. The Kinter K2020A+ amplifier uses only original Tripath TA2020-020 amplifier IC's - not like the fake or "wannabe" IC's found in other similar looking amps. The K2020A+ is a rarity and the real deal. Original Tripath IC's are rare and difficult to come by - and that's why the K2020A+ is a "Limited Edition" amplifier.

An Audio Legend

So, what makes the K2020A+ amplifier so special? First ,the technology inside. Tripath TA2020-020 chips are named as one of the "25 microchips that shook the world" by the IEEE - recognition that turns the head of any serious techie! Second, the proof is in the pudding, but in this case the pudding is the sound you hear (Note: no overselling, we acknowledge not all ears hear alike).

The K2020A+ amplifier offers the audio fidelity of a Class-AB design combined with the power efficiency of Class-D amplifiers.

Efficient and Powerful

The K2020A+'s clean 20 watt output makes it perfect for almost any auto or home audio application or DIY project. Small enough to fit in your hand yet big enough to power your home speakers. To ensure long life and stable operation we include a 12 Volt 5 Amp power supply that provides plenty of "horsepower" to the amp. You might ask, what's with the extruded aluminum case? To keep the cost down we didn't put her in a pretty little dress, her beauty is inside - plus the case acts as a heat sink to keep the amp running cool. Features gold plated RCA inputs, or use the 3.5mm jack for plugging in sources such as iPods, smart phones, or MP3 players. Convenient spring terminals (16 gauge wire recommended) make speaker connections quick and easy!

Nooelec Lana - Ultra Low-Noise Amplifier (LNA) Module for RF & Software Defined Radio (SDR) with Enclosure & Accessories. Wideband 20MHz-4000MHz Frequency Capability with Bias Tee & USB Power Options

Model: LaNA   |    Mpn: 100812   |    Ean: 0616469146564   |    PartNumber: 100812   |   Asin: B07XNLJ9X2

LaNA is a very high performance, wideband LNA module designed for general purpose SDR applications. Each module allows for 3 different power options, but you should only power with one option at any given time! The recommended power input through the SMA output port (for bias-tee capable SDRs like the NESDR SMArTee XTR) is 3V-5V DC. Alternatively, if you don't have a bias-tee capable SDR, you can use the external power options--the microUSB port, or DC barrel connector via the included DC to microUSB adapter. The recommended external power input is 3.3V-5.5V DC. Though there is protection circuitry on the SAWbird for overvoltage conditions--and voltages of up to 12V DC should still work and will not damage the device--it is not recommended for long-term usage. Kindly note that damage resulting from overvoltage conditions would not be covered under the standard 2 year warranty. Each LaNA module has an internal EMI shield to protect the sensitive circuitry from external interference and is fully ESD-protected.

Features

  • A wideband (20MHz - 4GHz), high-performance, general purpose LNA module installed in a quality aluminum enclosure
  • Higher gain, lower noise figure, lower power consumption and better linearity than modules based on SPF5189Z and similar LNA MMICs
  • Can be powered through bias tee (3.3V-5V), USB, or DC power with the included adapter. A free male SMA to male SMA connector is also included
  • Made in North America. 2 year warranty!

HiLetgo 3pcs ADS1115 16 Bit 16 Byte 4 Channel I2C IIC Analog-to-Digital ADC PGA Converter with Programmable Gain Amplifier High Precision ADC Converter Development Board for Arduino Raspberry Pi

 PartNumber: 3-01-1062-3pcs   |   Asin: B07VPFLSMX

Description:
For microcontrollers without an analog-to-digital converter or when you want a higher-precision ADC, the ADS1115 provides 16-bit precision at 3300 samples/second over I2C. The chip can be configured as 4 single-ended input channels, or two differential channels. As a nice bonus, it even includes a programmable gain amplifier, up to x16, to help boost up smaller single/differential signals to the full range. The chip's fairly small so it comes on a breakout board with ferrites to keep the AVDD and AGND quiet. Interfacing is done via I2C. Simply connect GND to ground, VDD to your logic power supply, and SCL/SDA to your microcontroller's I2C port and run the example code to start reading data.

Parameters:
ADC Bit rate: 16 Bit
Interface Type: I2C
Channels: 4 Channel AN0 AN1 AN2 AN3
Input voltage: 2.0v-5.5v
Channel input voltage : 0-VDD
Continuous Mode: Only 150 A
Single-Shot Mode: Auto Shut Down
Programmable data rate: 8sps-860sps
Input range programmed control, 7 types input ranges:
-0.256V ~ + 0.256V, -0.512V ~ + 0.512V, -1.024V ~ + 1.024V, -2.048V ~ + 2.048V, -4.096V ~ + 4.096 V, -6.144V ~ + 6.144V I2C 7-bit addresses between 0x48-0x4B

Package Included:
3 * ADS1115 16 Bit 4 Channel Analog-to-Digital ADC Converter 3 * Pin Header

Features

  • High precision ADS1115 16 Bit 4 Channel Analog-to-Digital ADC Converter
  • An easy to use I2C ADC Converter, with Programmable Gain Amplifier
  • Especially a good tool for Raspberry Pi that doesn't come with analog GPIO pins
  • Wide voltage supply range: 2.0V to 5.5V, operate in a comparator mode which is helpful for maintaining accuracy
  • Single-Shot Mode: Auto Shut Down; Programmable data rate: 8sps-860sps
