| + | we want to create a small STM32F4 based Board (for example 10x4cm in size), with limited Pins/sockets...\\ | ||
| + | [[FantomXR]] had made such a thing before, so we start with his working design, and invest some time in it\\ | ||
| + | see also this article: [[http://midibox.org/forums/topic/20732-another-midibox-core/?page=1|Another Midibox Core]]\\ | ||
| + | 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**\\ | ||

| + | ===== 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\\ | ||
