thingy 52 uart

[KVAJOH]

Hi Nordic, 

I'm starting a project using the Thingy 52 and I'm going to connect Thingy with another sensor.

 I have four communication options from the sensor:

UART, I2C, USB and SPI. 

I've seen a lot of mixed opinions on this, and I was wondering what option is supported by the Thingy 52, and how do I connect it? 

Thanks

Hi

Is there a specific reason for why you want to use the Thingy and not the nRF52 DK?  The thingy supports I2C, UART and SPI. The preferred communication protocol is based on the requirements of your application. Low power, data throughput etc.. The GPIO pins on the thingy can be configured to be used with the communication protocols. I suggest that you read through the Thingy's product specification for more information regarding the pin mapping. The product specification can be found here.

Hi Jared, 

Yes, I'm creating a hand-held SAR so I need the combination of IMU and BLE. The radar I'm connecting will stream a lot of data, so high throughput is important. I've read the document you're referring to and couldn't find any information on how to connect external hardware through UART. Are there any documentation on this? 

Thanks for the fast response

Hi

The PIN mapping shows which pins that are available for you to configure, for instance you can configure P0.02, and P0.03 to be Tx and Rx respectively. Then connect your external hardware to these pins and communicate with the hardware through the UART driver which is found in the Thingy SDK.

Alright, thanks.

Have a good weekend!
