Micro:bit board

[marc_is_curious]

Reference: bbc micro:bit (microbit) board Eagle schematic files

I heard that bbc's micro:bit board is based on Nordic's nRF51822 & build by Nordic Semiconductors

Since I would love to customise some of the Micro:bit board's features (e.g. & amongst others: directly adding IR & WIFI features on the board):

I looked at Github's 

- Eagle (all within "Eagle2" folder) 

- Kicad (all within "Kicad" folder) files 

... and tried to open/generate Microbit board's .pcb or .sch version but failed 

- to find these files 

- trying to add some of the source files to Eagle folders (in order to generate a .pcb or .sch version)

May you please let me know

- if/how I may generate or access Micro:bit board's Eagle .brd or .sch files?

- if there are any Eagle (or KiCad) versions of these files?

I look forward to hearing from you,

Best regards

Marc

Thanks for your reply & hint –

I contacted

- Micro:bit support & learned that there are Altium Software based open Source PCB files (via Github)

- Farnell (I assume that they produced it from what I read on BBC's Micro:bit project site ) & hope that they may provide links or even Eagle files

I had a look at NRF51 reference designs, liked them a lot!

The Micro:bit board is more suitable for my purposes. It comes with ...

- easy & plenty of coding examples & option for Microsoft's MakeCode (amongst other scripting options)

- LED Matrixes, Accelerometer, Magnetometer, Bluetooth, Nordic's nRF51822, embedded Buttons, lots of analog & digital & GPIO Pins etc.

- less expensive pricing (at least at Digikey)
