DC 5V to 3.3V Step Down Power Supply Module This is DC step-down module from DC 5V to DC 3.3V, those two DC voltages are widely used in digital and analog circuit board, - Input: DC 4.5 V-7 V (input voltage must be more than to output voltage high 1 V above.) - Output: 3.3 V, 800 mA (load current can't more than 800 mA) - PCB size:8.6* 12.3 mm - Package includes: 1x power module Note - Boost modules or buck module indicate the operating voltage, Please do not exceed operating voltage - Boost module output voltage can only be greater than or equal to input voltage, cannot be less than the input voltage! - Buck module input voltage must be higher than output voltage of 1.5V or 2V, otherwise it can not output enough power! - Cannot reverse polarity , or it will be short circuit, or will be born easily ! Ideal for electronics, Hobby, Raspberry Pi, Arduino experiment We specialize in electronics, computer and cable accessories Pickup Location: "Cable Link" Tel: 613-680-6188
