    • Revision 6
      • 2020-05-08 – Small board updates
        • Changed temperature sensor footprint (easier to solder)
        • Changed Large Capacitor footprint to fit better (16v 270uF)
        • Added pin headers for 1wire + GPIO0 (WLED Button)
        • Added 2×51Ω 0805 Resistor in data paths (provides additional anti-ringing)
        • Changed SS12 diode to SS24 (to have 3xSS24 diode in total)
        • Optimized power path layout further
        • Fixed header labeling mistake
  • Version 3
    • Revision 7
      • Dates
        • Pre-Assembled – 2021-04-30
        • DIY – TBD
      • Pre-Assembled and DIY (once available) combined changes
        • New pinout to make board Ethernet compatible
          • Very much geared towards ESP32 now, use v2 boards for ESP8266
            • Compatible with D1 Mini32, best to use a QuinLED-ESP32!
        • Optimized board layout improving signal integrity
        • Switched to 249R data channel resistors
        • Full 24v compatibility
        • Outputs renamed to LED1 and LED2 (fully Dual channel ws281x controller with ESP32!)
        • Extra 5vEXT pin headers near power input terminals
      • Pre-Assembled extra features
        • Custom DC-DC circuit
          • Auto Everything TM (matching main input voltage with LED voltage still required!)
            • No more Jumpers! 
            • Auto 5v-24v in for main AND 5vEXT (pre-assembled only!)
            • Auto input switching between main and 5vEXT
            • Enhanced 5.12v LED Data channel voltage boost
        • Always comes with ESP32 now!
        • No more Temperature sensor included by default
          • Pads and capacitor/resistor are still there, easily solder it on yourself!
  • Version 3.1
    • Revision 2
      • Dates
        • Pre-Assembled 2022-05
      • Added onboard resistor switches
        • Reworked Level-Shifter setup 
        • 2 channels with individual selection for 33Ω or 249Ω resistor
          • Default set to 249Ω 
          • Allows per channel selection for 3-wire or 2-wire power + data cable!
      • Renamed 5vEXT to vEXT since it accepts 5v-24v
      • Added auto-reset fuse to vEXT port
      • Removed “yellow jumper” LED1 output selection jumper
      • Added more copper clearance in some areas
      • Small silkscreen improvements
        • Added WLED logo to the board!
