The module features a simple four-pad layout for easy integration: : Positive Input Voltage (4.5V - 28V) IN- : Input Ground/Negative OUT+ : Regulated Positive Output OUT- : Output Ground/Negative Common Applications
: An onboard precision potentiometer allows users to fine-tune the output voltage to meet specific project needs.
: Always ensure the input voltage is at least 1.5V higher than the desired output voltage for stable operation. Hw-133-v1.0 Datasheet
The is a highly versatile DC-DC step-down (buck) converter module designed to efficiently lower a higher input voltage to a stable, lower output voltage. Widely utilized in robotics and DIY electronics, it is often favored for its compact footprint and high efficiency. Technical Specifications
: By using high-frequency switching, this module minimizes energy loss as heat compared to linear regulators. The module features a simple four-pad layout for
Due to its 3A current capability and wide voltage range, the HW-133 v1.0 is frequently found in:
: Always measure the output with a multimeter before connecting your load to ensure the potentiometer is set to the correct voltage. Widely utilized in robotics and DIY electronics, it
: Powering 5V servos or sensors from a 12V or 24V battery.
: Driving high-power LEDs that require consistent voltage and current.
: While rated for 3A, the module can get hot. If drawing more than 2A continuously, it is recommended to add a small heatsink or provide active cooling.
