Features: This DC-DC step down module can convert 12V to 3.3V, and there is also a 12V output. Specially designed two rows of needle fixing hole that can be directly fixed on universal PCB to extend the experiment. Using multiple input and output pins, easy to use and connect. There is a red power supply indicator light that you can check power state. Input voltage can be DC 6V to 12V, but input voltage should be 1V higher than output voltage. Specifications: Input Voltage: DC 6V to 12V Output Voltage: 3.3V ( 0.05v error), 5V ( 0.05v error), 12V (12V input directly to the output) Max. Output Current: 800mA (load current can not exceed 800mA) Size: Approx. 32 x 32 x 13mm / 1.26 x 1.26 x 0.51" Package Includes: 1 x Module Note: Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering. 1This DC-DC step down module can convert 12V to 3.3V, and there is also a 12V output 2Specially designed two rows of needle fixing hole that can be directly fixed on universal PCB to extend the experiment 3Using multiple input and output pins, easy to use and connect 4There is a red power supply indicator light that you can check power state 5Input voltage can be DC 6V to 12V, but input voltage should be 1V higher than output voltage
