The 48 Channel Mono / 16 Channel RGB LED Controller by Chromation Systems can be used to independantly control 48 groups/channels (up to 120ma per group) of mono-color LEDs or 16 groups/channels of common anode RGB LEDs. It utilizes 3x TLC5940 LED drivers controlled with a PIC 18F2550 microcontroller. The PIC runs at 48mhz, has USB connectivity and controls the drivers through a modified SPI interface. The default firmware uses 8-bit PWM(256 brightness levels) and has a 1.5khz PWM frequency. All LED anodes are connected in parallel and the cathodes are connected to the controller as the outputs sink current. There are 3 connection options for the LEDs, direct soldering, screw down terminal blocks, and headers/housings.
The primary firmware for this device is ColorMotion compatible, which works with the Chromation Systems ColorMotion software. ColorMotion is used for creating and uploading patterns to the device. There is also a open-source firmware version that is compatible with this device. The software for the mono LEDs is not yet ready, check back.
Using the full version ColorMotion firmware or the ColorMotion Demo firmware allows live control of the device over USB via emulated COM(serial) port. Accepts data extremely fast, over 100 frames/second.
This is the perfect kit for Infinity Mirrors, Case Mods, MAME Arcade buttons, LED art pieces, or anytime LEDs need to be controlled through USB or standing-alone.
