Frequently asked questions
Can I connect it directly to a 5 V microcontroller?
Not directly. The supply range is 2.3 V to 3.6 V, so power the device at 3.3 V, and use level shifting on the signal lines from 5 V logic to avoid overdriving the inputs.
Which SPI mode should I configure?
The device supports SPI modes 0 and 3, so set your microcontroller to one of these clock polarity and phase combinations.
