====== wCoreF4 PCB ====== This is the carrier board for the Waveshare Core407v. It performs breakout functions of all of the standard ports as per the design based on the STM32 Discovery. ===== Schematic ===== [[http://www.ucapps.de/mbhp/mbhp_core_stm32f4.pdf|The circuit is mostly identical to what was drawn previously.]] The following parts are different: ==== USB entry (J1) ==== {{::wcore:j1.png?nolink&200|}} This header supplies +5V, 0V, USB data and the ID state. Normally it will be connected to the [[wcore_usb|USB module]] by a short cable. ==== Extended port (J16E) ==== {{::wcore:j16e.png?nolink&200|}} The original J16 functionality is preserved, but extra pins are available on a IDC16 header. These include the Reset signal and pins normally controlling LEDs. This header is normally connected to the [[wcore_res-sd|RES-SD module]]. ==== User button (JPA0) ==== {{::wcore:jpa0.png?nolink&200|}} This jumper replaces the "bootloader" functionality of the Discovery board's blue button. It could be wired to an external panel control if needed. ---- ===== BOM v1.0 ===== ^Type ^Qty ^Value ^Package ^Parts^Mouser^Reichelt^Conrad^Other^Notes ^resistors^ | |2 |220R 5% |THT |R7A, R8A | | | | | | |2 |220R 5% |1206 |R7B, R8B | | | | | | |1 |330R 5% |THT |R102 | | | | | | |4 |1k 5% |1206 |R7B1-4 | | | | | | |2 |1k 5% |THT |R11, R13 | | | | | | |1 |10k 5% |THT |R12 | | | | | | |1 |220k 5% |THT |R101 | | | | | ^pots^ | |2 |10k |6*5mm vert |P1, P2 | | | | | ^capacitors^ | |3 |100n |1206 |C1A, C1B, C2 | | | | | ^diodes^ | |1 |1N4148 |THT | | | | | | ^transistors^ | |1 |BC337 |TO-92 | | | | | | ^ICs^ | |2 |74HCT125 |SOIC | |595-SN74HCT125DR|||Ensure **HCT**| | |1 |74HC595 |SOIC |T1 | | | | | ^Headers^ | |2 |1*2 |male | | | | | | | |1 |1*3 |male | | | | | | | |1 |1*5 |male | | | | |or wire directly| | |9 |2*5 |male | | | | | | | |3 |2*8 |male | | | | | | | |2 |2*8 |female | | | | | | ^Hardware^ | |4 |M3 spacer |8mm(?) | | | | | | ^MCU breakout^ | |1 |Waveshare Core 407v | | | | | | ===== Versions ===== v1.0: first release. ===== Assembly ===== ---- ==== License ==== Currently the design is (c) 2016 antilog devices with all rights reserved; all documentation is CC BY-NC-SA 3.0.
