I am designing a BLE device. Want to make the PCB as small as possible. to download the code/debug etc I need the a connecter on the board which can connect to the nrf52 preview dk development board. Is there any recommendation for a tiny connector? 8 pins will suffice. Such connectors can be found in mouser etc. The main issue is how to interface those connectors with the 10 pin connector used in the nrf52 preview dk? because I probably need an adaptor to connect it. Is there any tried/tested recommended combination for this issue?
thanks
