Hi.
You might be better off using the official DK builds at first: http://www.espruino.com/nRF52832DK
It'll be on P0.06 (RX) and P0.08 (TX), however in order for it to initialise the UART (since the UART takes a lot of power to run) you need to boot with P0.06 (RX) connected to a UART adaptor (it its idle state, the UART should be 3.3v, and this is detected)
