24 Channel High Current USB LED Controller - Old Versions
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 per channel. The various jumpers and transistor placement allow the device to control many different types of LED configurations with LED voltages of up to 36v.
Easily 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. Any combination of LEDs in parallel/series. Whatever kind/wattage/configuration can be made to work, to a max of 1A per channel or 2.5w dissipation.
A PIC18F4550 controls 24 high-current darlington transistors. The PIC is ready for USB communication and using Microchip's Library there is a multitude of USB connected devices can be made. From a simple emulated serial port, keyboard, mouse, HID, MIDI Devices, Audio Devices, and more. The available premium firmware allows the device to interact with the ColorMotion computer software, to create and upload patterns and settings to the device.
There are 4 pins left to use for other purposes, such as AdC, more transistors/MOSFETs, shift register whatever is needed. Accessed via the 6-pin polarized header, which can be used to connect to RA0, RA1, RA2, RA3, V+ and V-.
