The following tools and materials are required to assemble the PixiFlood Driver:Īdditional tools that might be helpful, but not required:Īdditional tools and supplies required to install driver into Housing: The version number is located on the bottom of the PCB. Assembly is identical, the location a couple of components is slightly different but the instructions are the same. I have begun shipping a new version, V1.9. THE FOLLOWING PICTURES ARE FROM THE V1.7 VERSION OF THE PCB. Some of the other changes was moving away from a linear voltage regulator to a switching configuration to address connections to higher voltage sources and overheating issues for the 5v circuitry. One of the other advantages of removing the direct connection is the trace length is less than 15% of the previous design which has yielded a significant drop in EMI and noise which has greatly improved the range of the ESP-01 wireless capabilities. All current LED chips are 36v or under so my circuit has plenty of headroom. By removing the direct connection and now connecting to the LED via soldered on wires, the new board is able to drive any led chip from 10w to 100w (or Higher) as long as the voltage requirement is under 60v. I started with that circuit and swapped out the PT4115 for another constant current driver, I've also eliminated the direct attachment of the LED to the board since this caused issues due to varied spacing requirements. Last year I created a 10w version of the Pixiflood with a built in PixelStick that worked very well. The esp-01 uses opensource firmware created for a device called ESPixelStick and works with E1.31 lighting software or directly with MQTT for home automation. I've ran into 2 issues, one the pin spacing is different between the various LED Chips and a trend for the LED Chips moving to 30-36 volts which are outside of the 30 volt max of the PT4115, so I set out to solve those two issues and also addressed being able to connect to wifi directly from the board using an esp-01. I wanted to expand to powers higher than 10w and had created boards to support 20w and 30w leds that only required 24 volts which was within the component specs. Its been a while since I reported on what was happening with the Pixiflood board.
