reserved pins and documantation inspection service.

[shlomots]

Hello, I have two questions.
1. First, are these pins reserved in the SOC level or DK level? this if from the nrf52840dk device tree.

meaning, if I have a custom board, should I still avoid using these pins?

2. Second, one time I was informed in the forum that nordic offer a service in which they take a look at your custom board documentation and sau if it's good fit for the SOC or not, I would love it if someone explands about this service, how much does it cost? how long does the evaluation take? 

thanks in advance, 
shlomo

Hi,

Please refer to the product specification (pin assignment) to see if there are limitations on the pins at the SOC level.
These pins (as defined in the gpio-reserved-ranges) are reserved in the board / DK level.

Nordic is happy to freely review your custom board files as long as you are using Nordic SOCs and our reference designs.

DK guides and SOC PS are here: Developing with nRF52 Series
