STM32H561 I2C2 data OK but USART3 baud rate at 1/3 of set baud rate

NUCLEO-H563ZI with STM32CubeMX 6.18.1 and STM32CubeIDE 2.2.0 reading in magnetometer data at 100 kHz then printing the data out the USART3 VCP. Baud set at 115200 but to read the data requires receiving it at 38400, one third the set baud rate. PLL

Multiple Devices on MiPi - VL53L9CX

Hello, Our setup uses a VL53L9-based board with an STM32N657 (NUCLEO-N657X0-Q). The sensor streams RAW8 over one data lane at 1 Gbps on VC0. We are using ST’s driver, and 54 × 42 at 100 fps works well.We would like to connect three or four sensors to
