Description: 1. On-board TDA2030A audio power amplifier chip. 2. Mono 18 w power amplifier circuit design. 3. On-board speaker terminal block 4 On-board 10k adjustable resistance, can adjust the volume of the amplification. 5. On-board power light. 6. Chip has lead to the main pin, can directly input audio signal. 7. Working voltage: 6 -12 v. 8. Board size: 31.6 (mm) x23.2 (mm). Package included: 5 x TDA2030A Audio Amplifier Module

Feature:   Onboard 2W mono amplifier (5V power supply up to 3W) can directly connected speakers (recommended with 4Ω3W speakers), 3.5mm gold-plated headphone jack can be accessed by headphones or external audio. With MicroUSB power supply interface, using mobile bank power or USB charger power supply, can also be used 3.7V lithium battery, USB 5V power supply. Support TF card (mobile phone memory card), U disk playback mode. With a speaker terminal without soldering, easy wiring.   1) Support MP3 format, power automatically play, led status turn to red. 2) Support U disk (tested with 32G), TF card (tested with 16G) playing mode, power default TF card mode, if the TF card does not exist automatically jump to U disk mode, and both devices are installed, you can manually set the playback mode, please refer to the key operation instructions.   Key operation instructions:   "Prev / V--" key: "short press" to switch "Previous" song, "long press" to switch "volume down" "Next / v ++" key: "short press" to switch "next song", "long press" to switch "volume increase" "P / P / Mode" key: "short press" to "play / pause" switch, "long press" for the U disk, TF card "mode" select "Repeat" key: "short press" for the "single / full song" cycle switch (no long press function)   Note:   1. Long press time about 2S 2. If you use U disk mode, the recommended 5V power supply, some U disk does not support 3.7V power supply.   Specifications:   Power supply range: 3.7 - 5.5V Product size: 45mm * 36mm   Package includes:   5 x MP3 Lossless Decoder Board

Description: This super small mono amplifier is surprisingly powerful - able to deliver up to 2.5 Watts into 4-8 ohm impedance speakers. Inside the miniature chip is a class D controller, able to run from 2.0V-5.5VDC. Since the amp is a class D, its very efficient (over 90% efficient when driving an 8Ω speaker at over half a Watt) - making it perfect for portable and battery-powered projects. It has built in thermal and over-current protection but we could barely tell it got hot. There's even a volume trim pot so you can adjust the volume on the board down from the default 24dB gain. This board is a welcome upgrade to basic "LM386" amps! CJMCU The A+ and A- inputs of the amplifier go through 1.0uF capacitors, so they are fully 'differential' - if you don't have differential outputs, simply tie the Audio- pin to ground. The output is "Bridge Tied" - that means the output pins connect directly to the speaker pins, no connection to ground. The output is a high frequency 250KHz square wave PWM that is then 'averaged out' by the speaker coil - the high frequencies are not heard. All the above means that you can't connect the output into another amplifier, it should drive the speakers directly. CJMCU Comes with a fully assembled and tested breakout board. We also include header to plug it into a breadboard and a 3.5mm screw-terminal blocks so you can easily attach/detach your speaker. You will be ready to rock in 15 minutes! Features: - Output Power: 2.5W at 4Ω, 10% THD, 1.5W at 8Ω, 10% THD, with 5.5V Supply - 50dB PSRR at 1KHz - Filterless design, with ferrite bead + capacitors on output. - Fixed 24dB gain, onboard trim potentiometer for adjusting input volume. - Thermal and short-circuit/over-current protection - Low current draw: 4mA quiescent and 1uA in shutdown mode Note: Speaker is not included, use any 4 ohm or greater impedance speaker. Package included: 5 x Audio Power Amplifier
