Thank you for your purchase! Now let's get started.

More details will also be in the datasheet which can be found in the project repository.
Hardware Setup
- Connect to a USB-C PD Compatible Wall Wart: Confirm USB-C PD support on a wall wart, check for "USB PD" markings or output specs above 5V (e.g., 9V, 15V, 20V) on the adapter. USB-C presence alone doesn’t ensure PD compatibility. Like this.
- Power On: Activate your Spark Analyzer. A blinking debug LED (5 times) indicates the firmware is correctly loaded.
WiFi Connection
- Connect to "Spark Analyzer" WiFi: Use a WiFi-enabled device like your phone or laptop to connect to the "Spark Analyzer" network. No internet is needed for this step.
- Configure WiFi: Open a browser, go to 192.168.4.1 to access WiFiManager, and set up your home or office WiFi credentials.
