This is an old revision of the document!
GM5 is an Atmel AVR based USB chip with preburned USB-MIDI firmware (out-of-the-box solution)
This product has been developed by http://www.ploytec.de
Schematics and Eagle file of the PCB: http://www.ucapps.de/mbhp_usb_gm5.html
The chip works under Windows/MacOS/Linux with the common USB-MIDI-Driver, but there is also a custom driver for Windows available to overcome the Microsoft driver flaws (a drawback of the old MBHP_USB module)
Per chip you will get 5 physical MIDI IOs. The dedicated Windows driver makes it multi-client capable. Under MacOS the interface is multi-client capable by default.
Package: TQFP32 (SMD, but can be soldered with a good soldering iron similar)
