Nordic Thingy:91 pin name ?

[Andy kang]

The nRF9160 is connected to the nRF52840 by MCU_IF0 ~7(GPIOs) in the Nordic Thingy:91.
and I know to uses UART communication between the nRF52840 and the nRF9160.
Can I know the assigned pin name (UART) for each pin  (MCU_IF0 ~7)?

Hi,

 

Those GPIOs (MCU_IFx) are connected to each respective GPIO, which is described in the documentation here:

https://infocenter.nordicsemi.com/topic/ug_thingy91/UG/thingy91/hw_description/pin_maps.html?cp=12_0_5_4

 

The default pin routing (and usage, if enabled) can be seen from the device tree files for targets thingy91_nrf9160 and thingy91_nrf52840:

Kind regards,
