Wx-dc12003: Schematic !!link!!

When you need a tiny, inexpensive way to power a microcontroller like an ESP32 or Arduino directly from a wall outlet, the WX-DC12003

Step 5: Locate the Feedback Divider

• Find the FB (feedback) pin on the IC. It connects to the junction of two resistors.
• One resistor goes to VOUT+, the other to ground. Measure their values to calculate output voltage.

The module typically utilizes a high-integration PWM controller IC. Based on community teardowns, the circuit consists of these primary stages : 85~265V AC to 5V 3.5W DC Isolated Power Supply Module wx-dc12003 schematic
