PAM8403 d-klassi helivõimendi moodul 4R/ch 2x3W 5V, 2.5-5V
1. Operating voltage 2.5V…5.0V. Note: Power supply voltage should not exceed 5.5V, the positive and negative terminals should not be reversed.
2. Recommended speaker with 4Ω…8Ω and 3W…8W power.
3. You can use the computer USB port 5V power supply, or use mobile phone charger USB port 5V power supply, you can also use lithium battery power.
4. High efficiency 90%, 4Ω load and 5V power supply conditions, can provide 3W (left channel) +3 W (right channel) output power.
5. Class D amplifier efficiency is very high, will not affect the sound quality because of temperature rise, and do not need heat sink.
VNH2SP30 mini mootori PWM draiver 1ch 14A 6-16V, loogika 3.3-5V
Features:
Today, speed and direction control of DC motors is very common. A Full-Bridge circuit is one of the simplest methods to control a DC motor. This module is a Full-Bridge motor driver with high output current tolerance.
INA, INB and PWM pins are used for controlling the speed and direction of motor rotation. The CS pin is also the current sensor. This pin’s output voltage changes 0.13V per 1A.
The input voltage should be between 6 and 16V. Also, the maximum allowed continuous output current is 14A.
This Module has 11 pins:
- VM: Module voltage
- GND: Module ground
- VCC: Module power supply
- GND: Module power ground
- OUT A: Positive end for motor A
- OUT B: Positive end for motor B
- PWM: Speed control signal for motor A
- INA: Motor Control signal
- INB: Motor Control signal
- CS: Current sensor
- EN: Activation pin
You can see the pinout of this module from the image.
