'''ESP Controller Carrier Boards''' are printed circuit boards (PCBs) designed specifically for holiday lighting applications. They transform an ESP module or development board into a complete lighting controller by adding the circuitry, connectors, and protection features required for reliable operation.

While an ESP module provides the processing power and network connectivity, a carrier board simplifies installation by integrating many of the supporting components commonly required for pixel control.

Typical features may include:

* Pixel output connectors
* Voltage regulation
* Logic level shifting
* Fused power distribution
* RS-485 transceivers for [[DMX]] and [[Renard]]
* Ethernet interfaces
* Screw terminals
* Status LEDs
* Push buttons
* Expansion connectors

Carrier boards range from inexpensive single-output controllers for small props to sophisticated multi-output systems capable of driving thousands of smart pixels.

== Why Use a Carrier Board? ==

Although many ESP development boards can directly control small pixel strings, carrier boards provide numerous advantages.

Common benefits include:

* Simplified wiring
* Improved electrical protection
* Reliable pixel signal generation
* Easier installation
* Better serviceability
* Support for additional communication interfaces
* Professional-looking finished controllers

The appropriate carrier board depends on the requirements of the display and the features needed.

== DIYChristmas Community Carrier Boards ==

The DIYChristmas community has produced numerous carrier boards over the years. Some were designed as simple single-output pixel controllers, while others provide advanced networking or support for legacy lighting systems.

=== ESPixelStick PCB ===

The ESPixelStick PCB was among the first carrier boards developed specifically for ESP-based holiday lighting controllers. Based on early work by Shelby Merrick and later expanded by Bill Porter and other contributors, these boards helped popularize inexpensive Wi-Fi pixel controllers throughout the DIY lighting community.

Several hardware variations have been produced over the years, reflecting the continuing evolution of ESP hardware and firmware.

'''Historical Notes'''

* One of the earliest dedicated ESP carrier boards for holiday lighting.
* Designed primarily for use with [[ESPixelStick]] firmware.
* Multiple community-developed revisions have been produced over the years.

=== PixelPop ===

PixelPop boards are compact carrier boards intended primarily for small props and single-output pixel controllers. They simplify installation by providing the supporting circuitry required for an ESP-based pixel controller in a compact package.

Several versions have been produced over the years with differing features and connector arrangements.

'''Historical Notes'''

* Intended for compact standalone props.
* Community-developed design with multiple hardware revisions.

=== FourStick ===

The FourStick is a community-designed carrier board intended for displays that combine smart pixels with traditional [[Renard]] lighting systems. By supporting both technologies, it provides an easy migration path for hobbyists transitioning from AC lighting to smart pixels.

'''Historical Notes'''

* Designed specifically for mixed Renard and pixel displays.
* Documentation currently exists primarily within DIYChristmas forum discussions.

== Commercial Carrier Boards ==

Several manufacturers produce professionally designed carrier boards for ESP-based lighting controllers.

=== QuinLED Family ===

The QuinLED family of controller boards, designed by Quindor, ranges from compact single-output controllers to advanced modular systems capable of driving very large pixel displays.

Depending on the model, features may include:

* Integrated level shifting
* High-current fused outputs
* Multiple pixel outputs
* Power distribution
* Ethernet support
* Expansion capability

Popular models include:

* Dig-Uno
* Dig-Quad
* Dig-Octa

Because the QuinLED product family continues to evolve, the official QuinLED documentation remains the best source for current specifications, wiring diagrams, and configuration information.

== Specialized Carrier Boards ==

Additional carrier boards have been developed for specialized applications including:

* WT32-ETH01 carrier boards
* Ethernet-based controller boards
* Project-specific controller designs
* Community-developed custom hardware

As new ESP modules and lighting technologies become available, additional carrier boards continue to be developed.

== Choosing a Carrier Board ==

Selecting the appropriate carrier board depends on several factors.

Consider:

* Number of pixel outputs
* Maximum pixel count
* Wi-Fi or Ethernet connectivity
* Firmware compatibility
* Available GPIO
* Power handling
* Expansion capability
* Ease of assembly
* Cost

Simple props often require only a single-output controller, while larger displays may benefit from carrier boards offering multiple outputs, Ethernet connectivity, integrated power distribution, or support for additional lighting protocols.
