Hi,
Is it possible to connect a device over UART (ideally not over the USB port) to the thingy:53?
Thanks!
its possible to connect a device over UART to the thingy53. The thingy53 is limited in terms of easy accessible GPIO pins but you can see the pin map here: https://infocenter.nordicsemi.com/topic/ug_thingy53/UG/thingy53/hw_description/pin_maps.html?cp=15_2_3_4
Depending on the use I think P0.04 and P0.05 could work.
Here's an unofficial example for low power UART created by one of my coworkers you can look to for inspiration
https://github.com/nrfconnect/sdk-nrf/tree/main/samples/peripheral/lpuart/boards
There is also an example in the nRF Connect SDK for low power UART in located in "NCS/v2.x.x/nrf/samples/peripheral/lpuart/"

Ok, a couple questions:
1. What does "depending on the use" mean in reference to P0.04 & P0.05? What does this depend on?
2. How are those pins physically accessed on the thingy:53?
Hi.
1. I don't think there are any good way to solder a connection to the pins. As I wrote in the my first post the thingy is limited in terms of easy accessible GPIO pins.
2. You can either use Stemma/Qwiic/Grove to access the 4 pin JST connector

Hi Runar,
In the diagram you sent I don't see P0.04 & P0.05 listed on the expansion board.
Hi Avi
They are listed as EXP_BOARD_PIN1 and EXP_BOARD_PIN2. However if you look in the pin map they are also described as P0.04 and P0.05
