Wxdc12003 Schematic Better -

Below is the (conceptual block diagram). Changes are highlighted in red.

Provides the critical "safety barrier" between the high-voltage side and your low-voltage project. Output Rectification & Smoothing: wxdc12003 schematic better

: Be aware that there are at least two distinct versions of this board: the original WX-DC12003 and a variant marked JL-AD3W-HT-V3 Below is the (conceptual block diagram)

Here is the ready for breadboard or PCB layout: 3.5W total power.

According to documentation from the All About Circuits forum and product listings: : 85V – 265V AC (or 100V – 370V DC). Output Voltage : 5V DC (±0.2V). Output Current : 700mA (nominal), 3.5W total power.
