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

USB entry (J1)

This header supplies +5V, 0V, USB data and the ID state. Normally it will be connected to the USB module by a short cable.

Extended port (J16E)

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 RES-SD module.

User button (JPA0)

This jumper replaces the “bootloader” functionality of the Discovery board's blue button. It could be wired to an external panel control if needed.
