IMPORTANT: This device requires a MiniUSB 5V power supply which supplies 500mA or more (not included) for stand alone use.  It is NOT recommend for use with passive USB hubs, only powered ones.

Basic Usage instructions:


Voltage Select switches:  Independent for each channel. Does NOT affect MIDI/I2C data

Slider LED color: To change the LED color, simply remove the cap and rotate the square LED 180s.  Do NOT force the LED back in, it should slide in easily, may require wiggling.


USB: Mini USB connection for power and/or connection to computer.  For use, simply connect to a 5V USB wall wart, 150 mA min (not included).  The device is a class compliant MIDI device and requires no drivers.

I2C: 2 buffered I2C ports.  Can be used as a small I2C hub

Dissassembly: Simply remove the 4 screws from the side without the connections, remove the side plate, and slide out the bottom of the device

PCB Rear:

Power backpack: This is the power supply for the device.  When converting to the eurorack configuration simply remove.  There is a standard 10pin power header below.



Module Config DIP switch: This allows you to switch between I2C Follower and I2C Leader modes easily.  Simply move the switch to the "lead" position and restart the module (you can press the blue reset button once).  The other 3 positions are for future expansion and not currently implemented.


 Includes 2m USB MINI Cable





Firmware update procedure:  Connect the Mini USB to your computer and press the blue reset button on the back of the module twice (quickly).  A new drive will appear on your computer, simply copy the firmware file to that drive (it will give you a warning about copying a file without properties).  The drive will disappear once the file is copied and the module will reboot with the new firmware.
