Does the BBC micro:bit have a serial port (not SPI)?

• "Answer" from http://www.espruino.com/MicroBit → No, no USART.
• "Answer" from https://en.wikipedia.org/wiki/Micro_Bit → Yes, serial I/O.

Does anybody know whether it will be possible to connect a sensor with a serial interface (+3.3V voltage level) ?

The MicroBit has a one serial port that's connected to the interface chip - but those pins aren't exposed to the user, so aren't marked on that page.

However the nRF51 is pretty cool in that you can remap pins anywhere. You should be able to use Serial1.setup(9600, { tx: .., rx : .. }) to re-map it - but then obviously you can't communicate with the micro:bit except via BLE.
