Pin connection for UART and SPI for Thing:91

[RamizB]

Hello,

I need to connect the Thingy:91 to an MCU via UART and/or SPI bus.  I need help to identify the pins for communications for:

SPI: CSK, CS, MISO, and MOSI

UART: Tx, RX

I would greatly appreciate it if you could provide the Pin ID for each; and a reference to photo will make it much easier.

Thanks for your help in advance.

Hello Ramiz, 

This information should be available in the Thingy:91 HW user guide. Have a look at the connector pinouts. Note that only the nRF52840 is available for external connection. 

Kind regards,
Øyvind

Hello Oyvind,

Thank you so much for getting back to me. i should have mentioned, that i have navigated through that page and particularly the HW document https://docs-be.nordicsemi.com/bundle/ug_thingy91/attach/Thingy91_UG.pdf?_LANG=enus

i could see the mapping for the pint of the SPI: CSK, MISO, and MOSI, but not for the CS.  I am not able to locate the pinout for the UART Tx, Rx.  Your feedback will be greatly appreciated.

regards with handshake :)

Hello, and thanks for your patience with this issue.

This is most likely due to the connectivity bridge. As these are connected to the nRF52840 and routed out through USB. You could probably access UART through P6 through devicetree configuration.

These are listed under e.g. ADXL372_CS
