Hw-133-v1.0 Datasheet -
: Once you reach your target (e.g., 5V or 3.3V), disconnect power and then connect your device. ЁЯТб Key Features and Use Cases
High-frequency multilayer ceramic capacitors placed across both input and output rails. These suppress voltage ripples and protect downstream devices from harmonic noise. Thermal Management Guidelines While the module is rated for a peak current of
Regulating 24V industrial rails down to 3.3V or 5V for microcontrollers. Design Considerations & Tips
, the board temperature remains stable without external modifications. Active Cooling or Heatsinking (
The HW-133 datasheet shines in its physical mapping. It clearly labels the 6 input pins (ENA, IN1, IN2, IN3, IN4, ENB). Hw-133-v1.0 Datasheet
The is a compact, high-efficiency DC-DC step-down (buck) converter module, typically based on the MP2403 synchronous rectified switch-mode converter . It is widely used in DIY electronics for its small footprint and low heat generation compared to older LM2596-based modules. Technical Specifications
Before diving into the details, here is a summary of the most critical parameters from the HW-133-v1.0 datasheet. A thorough understanding of these specs is the first step to using the module effectively.
write_register(REG_ADC_START, channel); delay_ms(2); val = read_register(REG_ADC_RESULT, 2); return convert_to_voltage(val);
As a step-down (buck) converter, the input voltage must always be higher than the target output voltage (e.g., a 12V input is recommended for a stable 5V output). Summary Table: HW-133-v1.0 vs. LM2596 : Once you reach your target (e
The HW-133-V1.0 operates on an asynchronous buck rectification topology, which ensures high power conversion efficiency even under significant voltage drops. The primary electrical performance parameters of the module include: Specification Monolithic Power Systems (MPS) MP1584EN Input Voltage Range 4.5 VDC to 28 VDC Output Voltage Range 0.8 VDC to 20 VDC (Continuously Adjustable) Maximum Output Current 3.0 A (Peak), 2.0 A (Continuous without extra cooling) Conversion Efficiency Switching Frequency 1.5 MHz (Maximum), 1.0 MHz (Typical) Output Ripple < 30 mV (At 1.0 MHz switching frequency) Quiescent Current Dimensions 22 mm ├Ч 17 mm ├Ч 4 mm Pinout Configuration
) registers firmly on the multimeter, power down the circuit, and safely solder your target electronic device to the output rails.
To maximize the benefits of the Hw-133-v1.0 datasheet, follow these best practices:
However, due to inconsistent labeling by Chinese manufacturers, some sellers list the Hw-133-v1.0 as a similar to the HC-SR04. Therefore, before working with any board labeled Hw-133-v1.0, always visually confirm its components. Thermal Management Guidelines While the module is rated
Often referred to as "Mini-360" or "Mini MP1584" due to its extremely small size and 360-degree component density. ЁЯТб Key Features & Protections
For high-vibration environments, some users remove the potentiometer and replace it with a fixed resistor to prevent the voltage from drifting due to physical movement.
The is a popular adjustable buck (step-down) DC-DC converter module, often featuring the LM2596 voltage regulator. It is widely used in DIY electronics to convert higher DC voltages down to stable, lower levels (e.g., dropping 12V or 24V down to 5V or 3.3V). Technical Summary & Field Performance
