We require 3.3V DC supply in many of the digital applications involving 3.3V developments boards like Arduino and sensors running on 3.3V supply. We can use USB outputs from mobile phone chargers or output from power banks for this purpose but these are all temporary solutions but if you require a permanent solution to this power supply issue you can use this Hi Link 3.3V 3W Switch Power Supply Module to directly power the device from 220V AC power supply and output is 3.3V and maximum wattage is 3W which translates to roughly 0.6A of DC current which is more than enough for powering your small DIY projects with small boards and sensors. It is small economic and reliable solution for powering your projects with noiseless operation. You can also mount it on PCB and breadboards too as they have compatible pins for it. It is widely used in a smart home, automation and control, communication equipment, instrumentation, and other industries.
