QuinLED-An-Penta Specifications

Back to QuinLED-An-Penta-DIY index page

The QuinLED-An-Penta is an Analog LED dimmer/controller board which uses an ESP32 and PWM to control 5 LED channels. It’s built with high power handling for total and per channel in mind and does everything “the right way” including 12v MOSFET gate drivers, 2x replaceable fuses, handling up to 36v and a board current capacity of 15~20Amps with 10Amps max per channel. Some other special features include the ability to hook up the board through Ethernet, dedicated switch/button terminals, having a temperature/humidity sensor onboard (for board temp measurements, not room!) and an OLED screen*!

It can run either WLED or ESPhome and it’s the perfect companion for Home Assistant if you want to run 12v or 24v LED strips, either high quality (CRI) white LED strips, multiple (CCT) white strips, RGB, RGBW or even RGB+CCT or whatever combination the 5 channels allow for!

*OLED screen does not work correctly when combined with Ethernet

Features

Please read till end to see maximum power figures!

  • Based on ESP32

    • 5v, 3.3v, 2x GND Terminals
  • Socket for SPI based OLED status screen
    • *Cannot be used together with Ethernet
    • If not used, extra GPIO pins can be used with DuPont cables!
  • 4x M3 mounting holes

 

Power Handling

  • Since this is a 4 layer board, power handling is based on 1OZ copper for all layers!
    • All testing has been done with a 1OZ,1OZ,1OZ,1OZ version!
  • For higher loads (above 10Amps total) please use both positive and negative input terminals with decent size wires to your power supply!
  • The 2x onboard fuses can be used together with any of the 5 output channels
    • When adding the SS36 “flyback/freewheeling” diode and running an inductive load feedback current will become important, please see board silkscreen for how the channels are divided!

Maximum per channel power

Maximum recommended power for a single channel is ~10Amps!

  • Higher will make MOSFET heat up too much
  • Output terminals also will heat up a lot with more then 10Amps current

 

Maximum total board power

The design goal of the board was to be able to fully utilize a Meanwell LRS-350-24 or the Meanwell UHP-350-24 (no fan, active PFC) which give you 350w of power so roughly 15Amps at 24v volt. If divided over multiple channels the board handles this without issue.

Maximum recommended power for total board is ~20Amps!

  • Higher will make positive input terminals to heat up a lot!
  • Fuses will heat up a lot running more then 10Amps a piece through them
