A CN11 3.5 mm stereo audio blue jack input is available on the STM32H735G-DK board for audio line input.
8.12 CN1 50 Ω SMA connector for ADC input
A CN1 50 Ω SMA connector is available on the STM32H735G-DK board. It can be connected either to a 16-bit
ADC input or to a 12-bit ADC input of the STM32H735IGK6U microcontroller. In order to get good ADC
performances, a low noise signal generator is recommended to provide an input signal.
