I don't have a battery for it yet so it's not actually keeping time. The documentation is poor, but I found a chip with a label ds13072, which suggest maybe it's the ds1307 driver. i2cdetect shows that on bus-es 10 and 22, port 68 is occupied, which also seems to match the ds1307 driver. Maybe it's enough just to try the sensing image and nothing needs changing?

I still haven't tested this, because I can't find a wired battery that would fit. The pin headers on the board look like pin hearders used by jumpers or USB headers or the Pi GPIO, but most batteries have a molex connector, which has a smaller distance between the pins.
