Re: X-nucleo-iks01a3's SPIs?

[QShan.1]

1. Are SPI_MISO/MOSI/CK/CS connected to STM32 MCU on the board? Logic Level 1.8V?

2. Are SPI_MISO/MOSI/CK/CS_O for external connections on the board? Logic Level Vio?

3. Are there a dedicated shunt for Vio connecting to 3.3V on the board?

4.If a 3.3V logic-level external SPI connects to SPI_SPI_MISO/MOSI/CK/CS_O, please advise me how to connect Vio to 3.3V on x-nucleo-iks01a3?

Thanks

Ciao @QShan.1 ,

1. Are SPI_MISO/MOSI/CK/CS connected to STM32 MCU on the board? Logic Level 1.8V? No

2. Are SPI_MISO/MOSI/CK/CS_O for external connections on the board? Logic Level Vio? No, this board doesn't support SPI, all the sensors are in I2C

3. Are there a dedicated shunt for Vio connecting to 3.3V on the board? All signals are level shifted and depending on the value of Vin (pin cn6.2)

4.If a 3.3V logic-level external SPI connects to SPI_SPI_MISO/MOSI/CK/CS_O, please advise me how to connect Vio to 3.3V on x-nucleo-iks01a3? No, as answered in question 1, this board can be used only in I2C.
