STM32 F4VE V2.0 175 contacts Current package STM32 F4VE board · Match the STM32_F4VE marking and 48-contact J2 and J3 headers. The board exposes separate LCD, microSD, SWD/JTAG, radio-module and serial connectors.
Power the board from USB Required Use a single USB cable to power the board through its native connector. Leave external power headers disconnected. Check the 3.3 V rail before attaching the debug probe.
USB power input USB return Board logic rail Bench checks Identify the USB power input and ground in the board schematic. Measure roughly 3.3 V between the board logic rail and ground. Check for a short or wrong connector if the rail is low. STM32 F4VE V2.0 connector map
Connection scenarios Attach an SWD probe Connect a 3.3 V UART console Connect a 3.3 V UART console Use an external 3.3 V logic-level adapter and keep the board on USB power. Cross transmit and receive, share ground and match the serial framing.
Board transmit Board receive Ground Bench checks Leave the adapter’s supply output disconnected. Enable USART1 on PA9/PA10 and verify that the host receives a known test string. STM32 F4VE V2.0 connector map
