STEVAL-MKI208V1K conecting to nucleo F401

[KDług.1]

Hello I want to connect to the STEVAL-MKI208V1K via STEVAL-MKIGIBV2 (conected those both togheter) , with Nucleo-F401RE. I conected pins as it is shown below

F401RE-> MKIGIBV2

MOSI (PB3 -> SDA

MISO -> SDO

SCK -> SCL

PWM/D6 -> CS

3v3 -> VDD

GND- >GND

I want to use SPI 4 wire interface but immediately after connecting nucleo to the PC I lost conection to the board and led LD1 starts blinking red. Do I need to connect some other pins as well with a board? Do I need to use some pull up resistors to the pins?

Hi @Konrad Długozima​ ,

You need to connect also VDDIO to 3V3.
