Manufacturer Variations: Research on All About Circuits indicates at least two distinct versions: the original WX-DC12003 and the JL-AD3W-HT-V3. I2S / SPDIF Out: This carries the raw

Usually a 4.7µF 400V electrolytic capacitor that smooths the rectified DC. The Controller IC: Need help troubleshooting your specific build

I2S / SPDIF Out: This carries the raw digital audio to the amplifier chip. If you have Bluetooth connectivity but no sound, this trace is primary suspect #1.
I2C Bus (SCL/SDA): This controls the amplifier chip (setting gain, EQ filters). If the amp is stuck in protect mode or muted, check these pull-up resistors.
Antenna Pin: Often a small U.FL connector or a solder pad. Bad solder joints here cause "low range" issues.
