Hw-044 Datasheet

One of the reasons the HW-044 is so popular is that it includes necessary peripheral components directly on the PCB. The module features:

| Parameter | Value / Description | | :--- | :--- | | | Stereo audio power amplification | | Core Chip | Texas Instruments TPA3110D2 Class D Amplifier | | Output Power | 2 x 15 Watts | | Key Feature | High efficiency Class D operation | | Typical Applications | DIY speakers, portable radios, upgrading TV/PC audio | | Dimensions (approx.) | 39 mm x 30 mm |

The HW-044 module is remarkably simple to use with an Arduino because the MAX3232 chip handles all the complex voltage conversion. This example shows how to echo data from a PC's serial port. The module can be powered directly from the Arduino's 5V pin.

The HW-044 is a "workhorse" module used in various fields where modern chips need to "talk" to older hardware: hw-044 datasheet

| HW-044 | Arduino Uno | |--------|-------------| | VCC | 5V | | GND | GND | | DIN | D11 (MOSI) | | CS | D10 (SS) | | CLK | D13 (SCK) |

On the HW-044, the SD_MODE pin serves a dual function:

// Send to motor driver (analogWrite for PWM) // ... motor control logic ... One of the reasons the HW-044 is so

: Remember that on the TTL side, you must connect the module's TXD to the MCU's RX and the module's RXD to the MCU's TX .

audio.setPinout(I2S_BCLK, I2S_LRC, I2S_DIN); audio.setVolume(21); // 0-21 audio.connecttohost("http://example.com/stream.mp3");

: Features a standard DB9 female connector for direct connection to a computer or industrial COM port. The module can be powered directly from the Arduino's 5V pin

: The TXD and RXD connections are frequently confused. Double-check your wiring. The HW-044's TXD pin is an output , so it must connect to your microcontroller's input (RX) pin.

As you've discovered, finding a single, unified hw-044 datasheet is impossible. Your path to technical documentation depends entirely on which module you have.
