Description
1. Function: Use low level to control high level. For example, the 3V or 5V voltage of the single-chip microcomputer is used to control the 9V or 12V voltage.
2. HVCC should not exceed 24V. The output current of the output port OUT1/OUT2/OUT3/OUT4 is equal to HVCC/5.1K, and the absorption current is 500ma.
3. This module uses Toshiba TLP281 chip
4. Schematic diagram:
5. Input and output description:
Input terminal: IN1/IN2/IN3/IN4, connected to the IO port of the microcontroller or arduino, and GND is connected to the GND of the microcontroller or the rrduino development board. IN1/IN2/IN3/IN4 respectively control OUT1/OUT2/OUT3/OUT4.
Output terminal: OUT1/OUT2/OUT3/OUT4
Output terminal: HVCC: connected to the controlled high-voltage positive pole, HGND connected to the controlled high-voltage negative pole
Use: When IN1 is high, the voltage of OUT1 is equal to HVCC, when IN1 is low, the voltage of OUT1 is equal to HGND
6. Examples of use
The following example shows how to use the IO port of the single-chip microcomputer to control the rotation of a 24V motor. The working voltage of the motor in the picture is 24V, the red " " indicates the positive pole of the motor's power supply, and the black "-" indicates the negative pole of the motor's power supply. When the IO_0 port of the single-chip microcomputer outputs high level, the motor rotates, and when the IO_0 port outputs low level, the motor stops rotating.

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.
