Hi,
I'm new here on working on improvment of my gas heating (Rehmea).
I won't to take my nodo otgw into operation and asking my self, if a shematic of that PCB is available.
As I see differences from the origine project. And like to understand.
I for example wondering, how the pwr sup is managed. As no 24V is needed.
Thx in advanced

Re: Nodo OTGW Shematics
The Nodo shop board adds an integrated USB serial converter. But the main circuitry is basically still the same as the original design. One exception is that the 24V is created from 5V using a boost converter, instead of converting 24V down to 5V. When I designed the OTGW back in 2009, boost converters weren't very common yet. If I had to redesign the thing today, I would also go with a boost converter.
