The HW-044 is not a standardized component like a 555 timer or a MOSFET. It is a breakout module assembled from generic parts. Therefore, no single company publishes an “official” datasheet under the name HW-044. Instead, the information is derived from:

The is a compact MAX3232 RS232 to TTL level converter module commonly used in DIY electronics to bridge communication between standard computer serial ports and microcontrollers like Arduino or ESP8266. Key Technical Specifications
Here is a quick look at the key specifications for the audio amplifier variant: Instead, the information is derived from: Have you
void setup() // Initialize hardware serial UART0 at 9600 baud Serial.begin(9600); // Print a message to the connected RS232 device Serial.println("HW-044 Module Ready.");
When configured for color sensing and frequency conversion, the S0 and S1 pins scale the output frequency to match the processing capabilities of your microcontroller. Power Down Mode (Low power consumption) S0 = L, S1 = H: 2% Frequency Scaling S0 = H, S1 = L: 20% Frequency Scaling
The HW-044's performance is defined by its onboard MAX3232 chip , which is an upgraded version of the classic MAX232 that supports lower voltage ranges.
