use nrf52 for smartwatch spi

jimkaragian

Dear support,

Our team is considered doing their own smart watch, so i found that nRF52 chip is a nice solution. Just before we start, i would like to do some basic questions so we will not spend much time to an dead end.

So my questions are:

1) i see that nRF52 supports SPI. But can i use this protocol with Arduino IDE (with this library for example https://github.com/adafruit/Adafruit_nRF52_Arduino ) that i am more familiar? I want to connect some accelerometer, oled and maybe 1-2 more sensors.

2) can i use this chip (click here)  or like this (click here) or this instead of the big development boards? Do we need a permission to make a final product?

Which module from the above you suggest? (use in Greece, Europe)

Thank you in advance

    IMHO, if you're going to make an actual product I suggest that you stick to our DKs and SDKs for development. 

    1. Sure you can use Adafruits SDKs and DKs, but we wont be able to help you with your development. 

    2. You need at least one nRF52 DK for debugging, and if you want our help then you need to use a HW plattform that we are familiar with, like our DKs. You're free to choose whatever tools you'd like, but we can only help you if you use ours. You do not need our permission to put your product on the market, but you will need to certify with ETSI, FCC, KCC, etc and BT SIG if you use BLE.
