Operating ambient temperature : -40~+85 Degrees Celsius . Size: 47.5*16mm / 1.9*0.6in Weight: 7g / 0.2oz (approx.)Package list: 1 * ModuleNote: This is a DC – DC voltage converter module, please pay attention when using: 1, The input voltage should not be higher than maximum input range; 2, The output power cannot be higher than the maximum load for a long time. 3, The input power must be higher than output power, because of the power consumption of the module itself. FAQ: Q: Why the output voltage is lower than the nominal voltage? A :Because the input power is too low a multimeter to test the input voltage, the input voltage is very low at this time.
