- Soldering Iron & Solder
Powering the EZNeo with a 5V Power Adapter #
If your control board does not have the capacity and/or headers (1.0A @ 5V) to power the strip directly, you can power them with a simple step-down module. We carry 5V step downs that have wires pre-soldered and pre-set to 5V for quick and easy installation. The only soldering required for our 5V adapter is the connection between the 5V output and the jumper wires to plug into the EZNeo 3 Pin plug for power. Jumper wires are included with our 5V adapter linked below.

- To see how to wire up our 5V power adapter see our guide here: EZNeo 5V Universal Power Kit Documentation
They will require you to solder to the step down to attach the power input and output wires.
IO Pin Wiring #
The V2.X (V2.0, V2.1, V2.2, V2.2.1) boards have 2 IO pins that are available to use. You can use any of these to control the EZNeo strips. Below is a picture showing the pin locations and their corresponding pin numbers. These boards are found in the Creality CR-10S series, CR-20, Ender 5 Plus, and Sovol SV01/SV02/SV03 printers.
Whatever pin you connect to will be the one you specify in the firmware. Nothing else can be using these pins, so choose one that is not used.
Firmware Setup #
Unified 2 Firmware #
If you are using our Unified 2 firmware, there are preset settings in the Configuration.h file to support the EZNeo strip. All you need to do is uncomment the line for the EZNeo strip you are using, uncomment the NEOPIXEL_PIN line, and enter in the pin number you are using.
Vanilla Marlin Setup #
If you are using a standard build of Marlin (aka “Vanilla” Marlin), follow the directions below to set the correct options to use the strips with your Marlin build. These directions are based on Marlin 188.8.131.52. Older/newer versions of Marlin may have different values than shown below.
Configuration.h Settings #
In Configuration.h make the following changes:
- Uncomment the NEOPIXEL_LED line
- Set the NEOPIXEL_TYPE to NEO_GRB
- Set the NEOPIXEL_PIN line to whatever IO pin you are using to control the strip.
- Change the NEOPIXEL_PIXELS value to 15
- Uncomment the NEOPIXEL_STARTUP_TEST line
Configuration_adv.h Settings #
In Configuration_adv.h make the following changes:
- Uncomment the LED_CONTROL_MENU line
These settings will enable all the Marlin RGB LED control options. You can change the LED colors from your printer LCD menu or through Gcode commands (M150)
