Hi,
I'm using wittypi4 mini on RPI zero 2w (I'm using Yocto build image).
I can start RPI using push button and also can see device on address 0x8 -> which is Wittypi.
When I want to use scripts for evaluating Wittypi I'm getting error:
root@raspberrypi0-2w-64:~/wittyPi# ./wittyPi.sh

[ 30.271140] rtc-ds1307: probe of 1-0068 failed with error -5
[ 30.277087] i2c i2c-1: new_device: Instantiated device ds1307 at 0x68
Seems Witty Pi board is not connected? Quitting...
Is there internally RTC connected to RPI I2C bus? So there are actually 2 RTC's on WittyPi? I cannot see any device on address 0x68 though. Any ideas please?
Thanks.
You have installed the wrong version of software.
Software version 2.xx is for Witty Pi 2.
There is a similar topic in this forum:

Thanks that did the trick.
One more question: can I power some external board using WittyPi VOUT pin also and not only RPI? What are current limitations please?
Thanks
@marekb please do not ask different questions under one topic, this has been clearly stated in our forum rules.
Also I believe the user manual or product page already lists the output current rating (usually under "Specifications" sector).
