PCB Footprints for Extra Capability

• 9x footprints for WS2812B RGB LEDs (COM-12667): RGB LEDs that glow through the bottom of the case (acrylic cases would be preferred)
• Footprint for a 4-channel DIP switch (210-4ES): A DIP switch is just 4 little switches combined into one (the Poker has one for settings)
• Footprint for a 2-pin JST-PH (PRT-09749): This is a power adapter plug for wireless builds (Bluetooth, etc.)
• Footprint for a 4-pin Qwiic (I2C) JST-SH connector (PRT-14417): Makes it compatible with Sparkfun’s Qwiic system
• Footprint for a clickable (worked into the matrix) rotary encoder (COM-09117, et al): This will spin and click to allow even more customization
• Footprint for a 6-pin male/female header (PRT-09015 or PRT-12590, et al): For development and DIY projects
