Re: Schematic and PCB of v1.5 microbit

All right. By the way, how many layers is this microbit PCB? Two layers or four? I don't know... I was going to reply and say "surely it's four layer..." but I took a quick look under the microscope for a few minutes and couldn't see any obvious evidence of more than the top and bottom layers (i.e....

There is 1.3 schematic,But I didn't find the PCB of 1.3.
There has never been a released PCB design for the "production" micro:bit. Only for the reference design.

Re: What are the open source C++ library for microbit?

Yes, the microbit-dal from Lancaster is probably a very good starting point. Really the next step from there is to go directly to either mbed or nrfx, but then you'll be doing everything manually. The microbit-dal is very straightforward to use (especially if you're using it with the mbed tools lik...

Hi,

Arduino IDE? See https://github.com/sandeepmistry/arduino-nRF5.

Thanks. The arduino-nRF5 have PIN define file only . I find another Full open source library :https://github.com/lancaster-university/microbit-dal/ Then,Is there any better library than this?

What are the open source C++ library for microbit?

Hi,Boy.I don't want to use the micropython library for microbit. Because micropython takes up a lot of space. So,now I'm looking for some C++ libraries for microbit . Do you have any recommendations? :lol:
