Specifications for v3 of the board, see v2 specifications here

QuinLED-Dig-Uno is part of the digital LED controller family and is an ESP8266/ESP32 powered WiFi connected addressable LED (strip) controller. It’s designed to be compact and an easy and especially safe way to run addressable LEDs. It’s best suited for small size installations, other boards are available for medium to large size installations!

QuinLED-Dig-Uno is suited for Clocked (Data and Clock pin) and Clockless 5v or 12v Digital LED strips with various chips such as the WS2812b (Neopixel), APA102/SK9822 (Dotstar) or SK6822 LED chips. Further the QuinLED-Dig-Uno has been tested to work with ESPhome (For Home Assistant), ESPixelstick (E1.31), Adafruit NeoPixelbus, FastLED and the excellent WLED firmware!

  • Uses Espressif ESP32 Micro-controller
    • Comes with QuinLED-ESP32 !
      • Compatible with all variants including Ethernet and can be selected during ordering
  • 2x Individual channel AHCT Level-shifter
    • 3.3v –> 5.12v level shifter for driving longer wire and strip lengths without flickering or corruption issues
  • 5v-24v voltage input and strip/pixel compatible
    • Input terminals for getting maximum input power through the board
    • “Auto” 5v/12v/24v custom DC-DC circuit
      • Auto selects input (if vEXT feature is used) and auto compatible with 5v/12v/24v
        • Input voltage = output voltage for the LEDs!
  • vEXT feature
    • Allows running the board with 2 power supplies
      • Enables running off standby power (5v phone charger for instance) while main high-power LED power supply is switches off with a relay
  • High current input and output terminals
    • Barrel connections can very much limit input power, screw terminals allow up to the rated 15Amps
  • Reverse polarity protection on input and output
  • Onboard ATO style fuse holder
    • Protects you against the worst failures!
    • In part to work in conjunction with reverse polarity input protection
  • Onboard capacitors to smooth out the current and prevent power supply inrush to the LEDs
  • Optional Onboard DS18B20 temperature sensor
  • 6 GPIO in/outputs available through pin headers (see pinout article)
    • Can be used for buttons, sensors, etc.
      • Dedicated button pin broken out with pull-up resistor
      • Analog audio input broken out (A0 pin)
    • Multiple 3.3v, 5v and GND pins available for buttons and sensors
    • I²C Bus pins available
    • Optional pull-high and pull-low hardware resistors
  • 4x Mounting holes
    • 4x M2
  • Small size
    • Fully assembled the size is about 5cm by 4cm with a height of 2,5cm

Power handling

There are dedicated input terminals on one side of the board and there are dedicated output terminals on the other side of the board to the left and right from the LED1 and LED2 data output terminals.

5v, 12v and 24v LED voltage compatible

Input voltage = Output voltage, match power supply voltage to LEDs!

Addressable LED strip often comes with separate Red (Positive) and White (Negative) wires to feed in more power into the strip directly and/or on both sides. I’ve designed the QuinLED-Dig series to handle as much amperage as possible through the board but there are limits. If more power is needed, please feed the strip directly next to doing so through the board, make sure to do so from the same power supply and properly individually fused!

Maximum input/output power

Maximum input and output power through board

Recommended sustained/continuous power ratings:
2OZ – 15Amps

Max “burst” power ratings:
2OZ – 25Amps
