The circuit implements mainly an interface between the Seatalk bus (12 Volt) and the Arduino (5 Volt). -The easiest way was to use the 74LS07 open collector driver device. This is much easier than most of the other implementations I have seen so far. The PCB also contains the voltage regulator (12-14 Volt from Seatalk bus to 5 Volt for the Arduino) and a 433 MhZ receiver. Please select/buy the right ProMicro device (5 Volt). There are also 3.3 Volt devices available. But the 3.3 Volt devices will not work. +The easiest way was to use the 74LS07 open collector driver device.

As antenna please use a short wire (e.g. 7,3 cm).
