If you encounter issues with Awinic products, we recommend the following troubleshooting approach: First, review our application notes and FAQs for common issues and solutions. Check the basics: verify power supply voltages, control signals, and I2C communication with an oscilloscope or logic analyzer. For audio issues, check speaker connections and verify output signals. For power issues, monitor switching waveforms and check for proper regulation. For RF issues, verify matching networks and measure S-parameters. If the issue persists, contact our FAE team with detailed information including: schematic and PCB layout, operating conditions (voltage, current, temperature), description of the issue and when it occurs, scope captures of relevant signals, and photos of the setup if applicable. Our FAE team can provide remote troubleshooting support or on-site assistance for critical issues.

Review our troubleshooting guides first, then contact our FAE team with detailed information for assistance.
