nrf52 pinout or dedicated pins

[Nils Minor]

Hi,

I was wondering about that I did not found any information about dedicated pin usage. I am using I2C/SPI and UART and did I understand it correctly that i can use nearly all of the pins for this, there is no dedicated pin/port?

I am also using PWM and since it is Hardware, not software anymore, can i also use every pin I want?

I have attached my Pinout/Pin usage, is this correctly?

best regards, Nils

Hi,

Yes, all the digital interfaces like I2C and PWM can be mapped to any GPIO pin. This can be done directly in the registers or using the drivers found in our SDKs. The only exceptions to the rule are the analog and NFC pins which are connected to a fixed set of pins which you can find in the pin assignment diagram.

If you plan to use a lot of serial interfaces at once then this thread is relevant.

Hi Martin,

thanks for your response, I understand this is good for my hardware design. I need I2C UART and SPI this should work i I use UART0, TWIM0 and SPIM, correct?

What about the PWM pins, can I use any pin I want ?
