Datasheet

UniPi
1Wire sensors
UniPi features single channel 1Wire master controller (DS2482-100, address 0x18). The 1Wire bus is
wired out via the RJ45 connector (see Table 5 for detailed description). The data line is ESD protected
and the 5V power current is limited to 200mA.

UART
The UART interface of Raspberry Pi is wired out via the RJ11 connector labeled UART. See Table 6 -
UART RJ11 connector. This port does not have any protection, so make sure to be careful when
connecting devices. Operating voltage of this port is 3V3.
