QuinLED-Dig-Uno

QuinLED-Dig-Uno has not been released yet! Will come somewhere in 2019!

QuinLED-Dig-Uno is part of the digital LED controller family and is an ESP8266/ESP32 powered WiFi connected addressable LED (strip) controller.

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), ESPpixelstick (E1.31), Adafruit NeoPixelbus and FastLED. Pins are available for each of the aforementioned software to drive either in DMA or UART mode on the ESP8266.

Features

  • Choice of Microcontroller!
    • Wemos D1 Mini (ESP8266)
      • Single-Core CPU at 80Mhz
      • WiFi 2.4Ghz 802.11N connectivity
      • Wide software compatibility through Arduino IDE, Micropython or other distributions
      • Onboard Micro-USB port and Reboot switch
    • MH-ET D1 Mini 32 (ESP32)
      • Dual-Core CPU at 240Mhz
      • WiFi 2.4Ghz 802.11N connectivity
      • Wide software compatibility through Arduino IDE, Micropython or other distributions
      • Onboard Micro-USB port and Reboot switch
  • Onboard 74AHCT125N DIP-14 3.3v –> 5v level shifter for driving longer wire and strip lengths without flickering or corruption issues
  • Dual Voltage (5v/12v)
    • Input terminals for getting maximum input power through the board (easily converted to barrel plugs if desired)
    • Selectable 5v or 12v design (input voltage = output voltage)
      • Jumper to set either 5v or 12v
        • If only 5v is desired you can save on component cost and not add the 12v components!
  • Parallel Diode reverse polarity protection on input and output
  • Onboard ATO style fuse holder
    • In part to work in conjunction with reverse polarity input protection
    • Determine fuse capacity by expected amperage + 15%
  • Space for onboard capacitors to smooth out the current and prevent power supply inrush to the LEDs
    • 2 spots, one is max 8x8mm (max 8mm high) the other is 10×10 (unlimited height)
  • Onboard DS18B20 temperature sensor
  • 4 GPIO in/outputs available through pin headers (see pinout article)
    • Can be used for buttons, sensors, etc.
    • 3.3v, 5v and GND pins available
    • Optional pull-high and pull-low with resistors available
  • 4x Mounting holes
    • 4x M2
  • Small size
    • Fully assembled the size is about 5cm by 4cm with a height of 2,5cm

Power handling

Power handling depends on the amount of copper that is applied to the PCB. Generally these values are 1OZ by default or 2OZ if you pay extra. Depending on your needs you need to select the right amount of copper you need in your boards.

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 clock and data output terminals. Input voltage = output voltage to the LEDs. If you build a 5v/12v switchable board, make sure to set the jumper into the correct position before you apply the new voltage. Putting 12v on the board with the jumper in the 5v position will fry the onboard components!

Addressable LED strip often comes with seperate barrel plugs or cables 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!
