TPA3110 XH-A232 30W+30W 2.0 Channel Digital Stereo Audio Power Amplifier DC 8-26V 3A C6-001 3110 Amplifier Board

Sound sensor module voice control switch strength detection audio amplifier microphone LM386

The LM386 is an audio integrated power amplifier with its own low power consumption, adjustable gain for updating the internal chain, wide supply voltage range, fewer external components and less total harmonic distortion. It is mainly used in low-voltage consumer products. In order to minimize the peripheral components, the voltage gain is built-in as 20, and by adding an external resistor and capacitor between pin 1 and pin 8, the voltage gain can be adjusted to any value within 200.

MAX7219 led dot matrix module 4 in 1 display module single chip microcomputer control drive module with 5p wire

MAX7219 is an integrated serial input/output common-cathode display driver, which connects a microprocessor and an 8-digit 7-segment digital LED display, and can also be connected to a bar graph display or 64 independent LEDs. It includes an on-chip B-type BCD encoder, multiple scan loops, segment word drivers, and an 8*8 static RAM to store each data. Only one external register is used to set the segment current of each LED.
