 +I have started a new Tread in the Forum, so we can discuss things there: [[http://http://midibox.org/forums/topic/20899-mnmlcore/|mnmlcore]], but i hope that most of the things will be done in the wiki, so it is more clear\\

 +=====the inital FantomXR Board:=====
 ==== Features ==== ==== Features ====
-- **...\\  +- **Size V0:** 98,5mm x 48,5mm \\ 
-- **...\\+- **Micro-SD-Slot**(flat @back on the board)\\ 
 +- **J8/9 SRIO** (for normal shiftregisters)\\ 
 +- **Midi A+B** (+HiSpeed? )(need external Optocoppler)\\ 
 +- **J30 Displays**(need external HC595)\\ 
 +- **Bootloader-Switch**(for program-alphas...debug)\\ 
 +- **onboard-Voltage-Regulator** (5V input regulated to 3,3V)\\ 
 +- **USB over Pinheader** (no onboard-socket)\\ 
 +- **USB-Power-Jumper**\\ 
 +- **J6+J7 - Pedals+Fader**:"for an AINSER64-like-analog-scanning", "I made some pcbs with faders which I connect directly to that connectors" \\ 
 +- **SWD-Header** (to program BOOTLOADER into board by using for a example a Discovery-Board)\\ 
 +- **Reset-Header**\\ 
 +{{:phatline:FantomX-Core-V0-connectors.png?600|}}\\ 
 + 
 +===== our modified Board:===== 
 +==== improvements ==== 
 +[[FantomXR]] made some improvement in his other projects, so we also should change this things:\\ 
 +"For example I changed:\\ 
 +the oscillator to SMD\\ 
 +all none-VDD-traces to 0.2032mm\\ 
 +all vias to round-style and 0.32mm diameter.\\ 
 +all 0603 SMD parts to 0805. 
 +removed the ID-pin from USB.\\ 
 +added an inductor behind the USB connector for EMC-improvements\\ 
 +" 
 + 
 +===== PCB Fabrication/Pick and Place:==== 
 +[[FantomXR]] have a pick and place machine, price he not knows up to now FIXME\\ 
 +need to ask him about the size of a sheet FIXME of multiple pcbs his machine can hold FIXME\\ 
 +find cheap PCB-Manufactor, which do this sheets FIXME for cheap FIXME\\
