Hey All,
The Pin Outs are here (edited 08/11/16, updated pinouts)

Enjoy!

Hi!

New pin outs are beautiful from the aesthetic point of view but the description of pins is not very clear to me. I prefered the style used for Wipy 1.0 pin out. For example the UART code in quick reference docs (https://docs.pycom.io/wipy2/2wipy/quickref.html) mentions UART_1 pins P3 and P4 but it I don't see that information in Wipy 2.0 pin out.

Best regards

Michal

I'm working in quick reference cards with only the basic informations.
Have a nice day,

Hi there,
yes same for me ... it's not clear where are located the 'default' I2C pins :-)
are P9/P10 (GPIO 12/GPIO13) ok when using example code in quickref doc i2c = I2C(0, I2C.MASTER, baudrate=100000) ?

thanks
Rico

You can refer to this until the official documentation is updated :

That's OK. What I am complaining about is the fact, that I can easily see the pin usage in Wipy 1.0 layout:
https://raw.githubusercontent.com/wipy/wipy/master/docs/PinOUT.png

but I struggle to find the same level of information for Wipy 2.0. For example I wasn't able to identify the fact that UART_1 pins are P3 and P4. It was probably caused by the lack of my knowledge (I don't understand properly some of those pin descriptions) but I might not be the only one who will need more intuitive pin out.

@Xykon
Thanks a lot, your schema is much more intuitive for me. Will you make a Wipy version too?

RicoLA

@Xykon yes that's to what I was referring to :-)

yet given this new "official" Lopy pinout pdf file, there are plenty of other possibilities with theses multipurpose GPIOs .

the problem is with alternate functions attached to them, we need to know precisely who is who . e.g. for I2C we need to know either the I2C bus number (like in : i2c = I2C(0, I2C.MASTER, baudrate=100000) ) , or the the SCL pin and SDA pin numbers that we can NOT mix up as we want. (as in i2c = I2C(scl=Pin(5), sda=Pin(4), freq=100000) )

cheers
