I'm building an RPi front end for my Mendel. I want to be sure I'm sufficiently powering the RPi, the Melzi board on my printer, and the peripherials (wireless network dongle and bluetooth dongle). I'm having trouble finding how much current the Melzi draws via the USB. The information was not on the Melzi wiki page or the Melzi GitHub, and I cannot find any kind of datasheet.
Does anyone know how much current the Melzi board will draw through the USB port?
