-# RGB Underglow Strip on the Zeal60: A Guide
-

-
-## Requirements
-
-- WS2812B RGB strip, preferably 60 LEDs/meter
-- Wire, solder
-- Tape, hot glue, or some sort of adhesive
-
-## A. Connecting the strip
-You might find the [**full PCB image**](https://cdn.shopify.com/s/files/1/0490/7329/files/zeal60jumpers.png) helpful. Ignore the red boxes!
-
-1. Connect V+ to the receiving end of the thermistor labeled F1; connect GND to the board's GND pin. (*Avoid connecting +V to the board's +5V pin* - you will likely overload the thermistor, and you will limit your maximum brightness.)

-
-2. Connect DI to PB0.

-3. Should look something like this when finished:

-
-*Optional:* To allow considerably more light to escape, consider angling the strip outwards by using some sort of fulcrum under the strip. (I used a thick wire.)
-
-## B. Enabling the strip
-1. If it is not present already, add the following to your ***keymap's*** ```Makefile```:
-
- ```Makefile
- RGBLIGHT_ENABLE = yes
- AUDIO_ENABLE = no #Underglow animations cannot be used with audio.
- ```
-2. If it is not present already, add the following to your *keymap's* ```config.h```, and edit the values as necessary:
-
- ```c
- // Set up RGB underglow.
- #define RGB_DI_PIN B0 // The pin your RGB strip is wired to
- #define RGBLIGHT_ANIMATIONS // Require for fancier stuff (not compatible with audio)
- #define RGBLED_NUM 35 // Number of LEDs
- #define RGBLIGHT_HUE_STEP 5 // How much each press of rgb_hue changes hue
- #define RGBLIGHT_SAT_STEP 10 // How much each press of rgb_sat changes sat
- #define RGBLIGHT_VAL_STEP 10 // How much each press of rgb_val changes val
- ```
-3. If they are not present already, add the following keycodes to your keymap to control the RGB strip: ```RGB_TOG``` (on/off), ```RGB_MOD``` (step through modes), ```RGB_HUI```, ```RGB_HUD```, ```RGB_SAI```, ```RGB_SAD```, ```RGB_VAI```, ```RGB_VAD``` (HSV increase/decrease). Add these to your keymap.
-
-## C. Dealing with current limits
-USB 2.0 ports on laptops provide up to 500mA max, but USB 3.0 ports can provide up to 900mA; USB 3.1 up to 1.5A; and powered USB hubs even more. We can run our keyboard at a higher brightness if we draw more power. **The Zeal60 uses 500mA at max brightness.** This means that **you have about 400mA remaining for the strip to use on a USB 3.0 port**; 1000mA free on a USB 3.1 port, so on and so forth.
-
-***Warning:*** **This means you will need to turn *off* your RGB strip before connecting to a USB 2.0 port**, as USB 2.0 cannot sustain the current necessary!
-
-1. If not present already, add the following to your keymap's ```config.h```. Change the numbers based on your needs. The ones below are safe underestimates.
-
- ```c
- // Enable current limiting for RGB underglow.
- #define RGBSTRIP_CURRENT_LIMIT 400 // Strip current limit in mA. (USB amperage - 500mA for keyboard)
- #define RGBSTRIP_MAX_CURRENT_PER_LIGHT 50 // mA per light when at max brightness.
- ```
- *Example:* I use a USB port capable of providing 1800 mA. The keyboard uses 500mA, so my personal value (in the `tusing` keymap) for `RGBSTRIP_CURRENT_LIMIT` is 1300. The particular WS2812B RGB strip I have uses a maximum of 60 mA per LED, so that is my personal value for `RGBSTRIP_MAX_CURRENT_PER_LIGHT`.
-2. Toggle on the LED strip (```RGB_TOG```) and step through animations (```RGB_MOD```) to test it out!
