Nrf52832 uart

[omar]

Hi every body , i have some issue if you don't mind. i rooted a board with NRF52832 SOC without PCA. i want to get a uart connection with pin 8 and 10 . It s possible to do serial connection through the soft !!

Hi,

You can use the UART on pin 8 and 10.

• What do you mean by "rooted a board with NRF52832 SOC without PCA" ?
• You have made a custom board?

Yes, i make a custom board without using any of PCA. whath i mean that it's posible that the NRF pin 10 and 8 support uart connection with +5 V level !!

[Sigurd]

As shown here, the max is VDD + 0.3 V, and max VDD is 3.9V. Recommended VDD is between 1.7V and 3.6V.

In order to use 5V for UART, you will need to use some level shifters. Using 5V directly on the nRF-Pin is not possible.

Thank you for your help !
