====== mnmlCore ====== **--at the moment obsolete-- because there is [[dipcoref4]]!!!**\\ 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\\ ===== Introduction ===== ...\\ ===== a Name ===== mnmlCore, miniCore32, 10x4CORE, RFcore, fundimentalCore, basisCore, baseCore, XRcore, midicore ====== Design Concepts ====== phatlines idea with onboard-split-cut MidiIO: {{:phatline:desing-concept-midi-port.jpg?1000|}}\\ ====== PCB ====== =====the inital FantomXR Board:===== ==== 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\\ ====== Hardware Requirements ====== * a jtag programmer (or a Discovery Board) * Soldering Iron, Wires, PCB....\\ * USB Power Supply ===== Resources ===== [[http://midibox.org/forums/topic/20899-mnmlcore/|Forum to discuss]]\\ ====== Community users working on it ====== * **[[Phatline]]** = Documentation, PCB-layout-or at least give it a first try...\\ Just let a Private message on the forum to user already involved
