I can't find an email on the website so I open an issue here.

Bad contact seems to make appear and disappear the device on the I2C bus.

So I want to solder the piface RTC I have on the gpio pin (any other non definitive solution ?) But what pins do I need to solder ?

There is no mention in the doc of the GPIO pin used ?

my guess would be GPIO 3 and/or 5 and may be 1 and some ground on 6 or or 14 or 25.

Please respond here and also update the doc accordingly. Thanks

So following what could easily be found like on that site https://pinout.xyz/, I soldered only the pin 1, 5, 6

It's working perfectly now. No more bad contact making the RTC appear and disappear.
