*Note that each side has 3 selection points, so if it was needed, the main trace could be cut at any point and transistors on the same side could be mixed sink/source. See datasheet for more jumper selections. Set 16(Output1-16) to Sink and 8(Output 17-24) to Source SELx to NEGx for sink, SELx to POSx for source. Side can be set to sink or source voltage based on the SEL jumpers and the position of the transistors. The board's transistors are laid out with 16 on one side and 8 on the other. This board features jumpers to select if the transistors will be sinking or sourcing current. R26 and R27 are 22 ohm (Red - Red - Black) for the USB Data lines, these must be crossed on version 3 PCBs, one on the top side, and one on the bottom side R25 is a 10k ohm (Brown - Black - Orange) pull-up for MCLR Start with the transistor base resistors, R1-R4 are all 1k ohm(Brown - Black - Red) LEDs or LED Strip, Find Some In The Storeįor controlling lower current LEDs over USB, please view 48 Channel Mono / 16 Channel RGB LED Controller All from the same controller.ĬhromationSystems-24ChanUSB_v1-1-eagle.zip (80 KB)ĬhromationSystems-24Chan-Project-Files-v3.zip (4 MB)Įlectronics: Purchase a Kit from The Store or Purchase a PIC or PCB separate.Ģ4x MPSW45AG Darlington Transistors or similarĢ0 mhz, version 3 can use any type, v1 & v2 require a series oscillatorĢ4x 1k ohm 1/6w resistor, value may vary depending on transistorħ805, 5v regulator, optional, can't be used in most casesīutton assembly parts: Momentary Push button, perfboard, ribbon cable, and 10kohm resistor Here the v1 hardware controlling a 3w white LED, a 5mm blue LED, and a few The 48 Channel Mono / 16 Channel RGB LED Controller, which is also USB connected, and is made for lower current LEDs is now available.ġ. It is a single sided version of this circuit, so it is very DIY PCB friendly. The zip includes PCB diagram, Schematic Layout, and drill files. Previous Version Assembly Instructions, Datasheet, Updates and More Info Can Be on the Main Website There are kits available in the Chromation Systems Store and all the files to recreate this project is in the ZIP file below. It accepts data from a PC/MAC/Linux over emulated serial port to the circuit board which outputs 8-bit Accessed via the 6-pin polarized header, whichĬan be used to connect to RA0, RA1, RA2, RA3, V+ and V-.ase. There are 4 pins left to use for other purposes, such as AdC, more transistors/mosfets, shift register whatever is needed. The available premium firmwareĪllows the device to interact with the ColorMotion computer software, to create and upload patterns and settings to the device. From a simple emulated serial port, keyboard, mouse, HID, MIDI Devices, Audio Devices, and more. The PIC is ready for USB communication and using Microchip's Library there is a multitude of USBĬonnected devices can be made. Whatever kind/wattage/configuration can be made to work, to a max of 1A per channel or 2.5w dissipation.Ī PIC18F4550 controls 24 high-current darlington transistors. AnyĬombination of LEDs in parallel/series. The various jumpers and transistor placement allow the device to control many different types of LED configurations with LED voltages of up to 36v.Įasily controls 5mm, 1w, 3w, 3w RGB, 5w RGB, 12v RGB LED lightstrip, 12v solid color light strip, common anode RGB LEDs, common cathode RGB LEDs. This device is designed to be a versatile high-current LED controller, with the ability to sink or/and source currents up to 1A per channel with dissipation of up to 2.5w perĬhannel.
