DIY USB Linear Voltage Regulator Multi-channel Output Power Supply Kit Step Up Module

DIY USB Linear Voltage Regulator Multi-channel Output Power Supply Kit Step Up Dual Power Feature: - Single voltage wide range input, can connect to USB, with input current limiting protection. - Multi-channel linear regulator dual output, which to meet most of the experiments required - Small size, easy to use - Input voltage: 5~18V DC - Output voltage: +12V, -12V, +5V, -5V, +3.3V, +9V - Output current: max 300mA (per channel) Package incluede: 1 x Multi-channel Output Power Supply Kit The input end connected to the 5V power adapter with USB cable, then tested the output voltage: 1. Output +9V ,and tested it, the accuracy is high. 2. Output +5V 3. Output -5V 4. Output -12V 4. Output +12V Drived the 12V/200mA fan with 5V/1A mobile phone charger, and worked normally. Used mobile phone charger whose output is 5V/1A to supply +5V, +12v, -12V voltage to the DDS waveform generator, and it worked perfectly.
