ESP-32 WLED WiFi Controller

The KEHIPI YS1603 kit bundles an ESP-32 based SP803E controller that drives addressable and PWM LED strips over Wi-Fi using the WLED firmware. It suits hobbyists and installers who want browser or app control of custom lighting projects without writing code. The board accepts 5 V, 12 V or 24 V DC input matched to the strip voltage and includes reverse-polarity, backfeed and data-port surge protection. No LED strip or power supply is included in the package.

Thermals noise and power

The controller draws minimal idle current and runs silently at 0 dB because it has no moving parts or active cooling. Heat output stays low in normal operation across the supported voltage range, so no heatsink or airflow planning is required. Power consumption scales with the connected LED load rather than the controller itself. Builders must size the external DC supply to the strip's voltage and total wattage.

UART USB-C and bundled sensors

A USB Type-C UART port provides direct firmware uploads and serial debugging without extra adapters. The kit also ships with four YS7903 leak sensors that extend the system into water-leak detection over YoLink, adding a safety layer unrelated to lighting. Both the programming interface and the sensors are ready to use out of the box with no additional hardware.

Questions about this item

How do I connect a WS2812 strip to the ESP-32 WLED controller?

Wire the strip's power, ground, and data input to the controller's matching terminals; the step most people miss is ensuring the supply voltage matches the strip's rated voltage.

What will need replacement first on the YS1603 kit?

The power supply and LED strips are external components; the controller itself has no user-serviceable parts and no stated maintenance interval.

What limit appears first when driving 2048 pixels continuously?

The controller caps addressable output at 2048 pixels for RGB or RGBW ICs; sustained full-brightness operation may hit thermal or voltage-drop limits before that pixel ceiling.
