The exposed copper will oxidize over time. The datasheet never mentions this, but conformal coating or simply accepting the board as a consumable part of your garden project is the way to go.
Delivers the regulated, stepped-down DC voltage to your load circuit.
. On the adjustable version of the HW-133-V1.0, a precision multi-turn trimmer potentiometer is wired into this feedback loop. Rotating this potentiometer modifies the division ratio, altering the steady-state target voltage at . Operational Best Practices & Thermal Limits Hw-133-v1.0 Datasheet
The is an ultra-small, non-isolated DC-DC step-down (buck) voltage regulator module widely used in DIY electronics, robotics, and embedded systems. Built primarily around the high-frequency MP1584EN (or GW1584/XM1584) step-down converter integrated circuit, it delivers an adjustable output voltage from a higher input source with up to 96% energy efficiency.
A small, top-actuated potentiometer used to adjust the output voltage. Turning counter-clockwise lowers the output voltage. The exposed copper will oxidize over time
Understanding the technical limits of the MP1584 module is critical for reliable circuit design. Specification 4.5V - 28V 12V or 24V sources recommended. Output Voltage 0.8V - 20V Adjustable via potentiometer. Output Current 1.8A (Typ), 3A (Max) >2A requires heat sinking. Conversion Efficiency Varies based on input/output ratio.
