====== 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.
