Problem on accessing the P0.00 and P0.01 and also rebooting issue

Hi 

I read this Q&A: How to configure the P0.00 and P0.01 pins as GPIO, which is similar to my question. There are some things I did not get from that section:

  1. "Physically removed" means cutting bridges SB1 and SB2.

  2. What do you prefer to use between a 32.768KHz external and a 32 kHz  internal RC oscillator for a product?

  • Hi,

    "Physically removed" means cutting bridges SB1 and SB2.

    The answer in that thread was referring to a general custom board. For our development kit, more specifically our nRF52840, you can disconnect the external crystal from the GPIO pin by cutting the solder bridge SB1 and SB2.

    What do you prefer to use between a 32.768KHz external and a 32 kHz  internal RC oscillator for a product?

    32 kHz external crystal since it's much more accurate and will not drift over temperature,
