nRF52832 signal voltage level for SPI devices with voltage lower then nrf VDD

[Ars Morozov]

Hello.

I use nRF52832 and power from 3.3V source. Also I use the accelerometer and gyroscope with VDD 2.5V and 3.0V respectively. They are connected to nRF through SPI. Is it possible to configure SPI on nRF to work on voltage level that different from nRF VDD. So, how can I make those configurations?
How can I configure SPI to work with device logic level 2.5V?

Tnaks in advance.

Hi,

You should make sure the voltage levels are within the Electrical specification of the GPIOs. If the voltages are below this, you will need a level converter between the devices to make sure the communication is working correctly.
