Does nRF52840 has capsense/capacitive touch supported pins?

[Parth Parekh]

if available can you please share the pins supporting touch and the design guideline for capacitive touch pad design with nRF52840.

Hello,

Any analogue pin can support this. I do not think we have any design guidelines for capacitive touch pad. This is supported in nRF5 SDK https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v12.0.0/hardware_driver_comp.html?cp=9_5_12_2_3_1_0#hardware_driver_comp_csense .

We have an example https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.1.0/lib_csense_example.html?cp=9_1_4_6_5 for testing capacitive sensor. This is very old example. It is only proof of concept. Not for production quality.

Thanks.
