Limitations:
On STM32H735G-DK board, PA0_C input is connected either to ARD_A2 signal (CN9 ARDUINO
®
connector) or
to ADC_IN signal (CN1 SMA connector), thanks to solder bridge configuration. As a consequence, when using
ADC_IN line, the user must make sure that ARD_A2 is unconnected and vice versa.

Uno V3 connectors
CN4, CN5, CN8, and CN9 ARDUINO
®
Uno V3 connectors are female connectors compatible with ARDUINO
®
Uno Revision 3 standard. Most shields designed for ARDUINO
®
Uno V3 fit the STM32H735G-DK board.
Important:
The STM32 microcontroller I/Os are 3.3 V compatible instead of 5 V for ARDUINO
®
Uno.
Limitations:
On the STM32H735G-DK board, SPI5 signals are sharing the same IOs with SAI1 and UART7. As a
consequence, when using SPI5 signals on the ARDUINO
®
connector, the audio codec SAI1 interface cannot be
used. Same, the user must make sure that nothing is connected on STMod+ (1,2,3,4 pins) and Pmod
™
(1,2,3,4
pins) connectors.
