Advanced LEDs

This page covers advanced LED options including custom logo PCBs for StealthChanger.

Rainbow Barf LEDs

Rainbow Barf LEDs are small PCBs with 1.5mm RGB LEDs arranged in the Voron or Micron logo pattern. These compact boards are designed to mount on toolheads and provide logo lighting. They can be purchased online now without ordering PCBs yourself.

Hardware

  • PCB Source: Rainbow Barf LEDs

  • LED Type: SK6805-EC15 (1.5mm RGB LEDs)

  • Use Case: Toolhead-mounted logo lighting

Configuration

Configure in your tool config file (stealthchanger/tools/Tx.cfg) for toolhead mounting:

[neopixel rainbow_barf]
pin: toolhead:PB3           # Pin on toolhead board (CAN bus)
color_order: GRB            # SK6805 uses GRB order
chain_count: 21             # 21 for Voron, 19 for Micron
initial_RED: 0.3
initial_GREEN: 0.3
initial_BLUE: 0.0

Or in printer.cfg for frame mounting:

[neopixel rainbow_barf]
pin: PB3                    # GPIO pin (adjust to your setup)
color_order: GRB
chain_count: 21
initial_RED: 0.3
initial_GREEN: 0.3
initial_BLUE: 0.0

StealthChanger Barf (SC Barf) LEDs

SC Barf LEDs are larger PCBs with 1.5mm RGB LEDs arranged in the StealthChanger logo pattern. These are designed for frame mounting and provide prominent logo lighting.

Hardware

  • PCB Source: SC Barf LEDs

  • LED Type: SK6805-EC15 (1.5mm RGB LEDs)

  • Use Case: Frame-mounted StealthChanger logo lighting

Configuration

Add this to your printer.cfg:

[neopixel sc_barf_logo]
pin: PB3                    # GPIO pin (adjust to your setup)
color_order: GRB            # SK6805 uses GRB order
chain_count: 21             # 21 for Voron, 19 for Micron
initial_RED: 0.3
initial_GREEN: 0.3
initial_BLUE: 0.0

Ordering PCBs

The SC Barf PCBs can be ordered from JLCPCB:

  1. Add the Gerber zip file from the SC Barf repository
  2. Select PCB quantity and color
  3. Select Order Number(Specify Position)
  4. Enable PCB Assembly
  5. Select Added by Customer in Tooling holes section
  6. Add BOM file BOM-JLC.csv
  7. Add CPL file CPL-JLC.csv
  8. Process BOM & CPL and verify component placement
  9. Complete checkout

If SK6805-EC15 is out of stock, DY-S1515065/RGBC/6805-5T by TONYU is compatible but the JLC footprint is rotated 180 degrees. Verify correct orientation during placement.

Toolhead-Specific SC Barf

Some toolheads have mods for SC Barf LEDs:
