Working temperature: -40 to +85
Peripheral size: 43*21*14 (length * width * height) (mm)

Features:
1.The module uses high-quality LM2596 chip, high efficiency (maximum 92%), low heat generation, and can easily bring 3A (short-term) current. It is recommended to use current within 2A for long-term work, and add a heat sink (above 10W) Output).
2.This module uses the original Sanyo filter capacitor with low ESR, which can make the ripple voltage as low as 30mV, which is completely comparable to the linear power supply!
3.This module uses machine placement, reflow soldering, and each module undergoes a two-hour aging test before shipment to ensure high reliability.
​
Wiring:
1. Soldering, directly solder the power cord to the input (output) port
2. Welding pins can be used by inserting pins through lead wires or inserting into holes on the board; or soldering the PCB directly after adding pins.
