From da14531 module datasheet the operating voltage is 1.8 - 3.3 . for my application i need to connect a sensor with operating voltage of 1.8 V. I have a custom board of module and USB development kit. the custom board is powered with 1.8 V regulated supply and in GPIO pins ,also the readings are 1.7 - 1.8 V .
Is there any way to power up USB development kit with 1.8 V.?
In sdk , there is power rail to configure pin power to 1V or 3V , and there is syscntl.c which we can configure multiple power configuration like buck , boost with varied voltage levels.
My requirement is set GPIO voltage level to 1.8 V without any regualator circuit. is it possible with dialog module?
