About the Domonode inputs PCB
Domonode inputs is an open source PCB design by NdK73, published on GitHub under the MIT license. It is a 2-layer board measuring 95 × 80 mm, with 54 components from 10 distinct parts.
Other key parts include the TLP620, PCA9555 and 24LC02. By type, the board carries 22 capacitors, 16 resistors, 13 ICs and 3 connectors.
From the project
DomoNode, DomoNode-inout, DomoDisp, etc.
This project consists of a protocol spec, the design files for physical nodes and the source code that glues it together.
Full protocol description is available, together with examples of a monitor and a sender. The protocol is text-based to ease debugging.
ClearSky technology inside: the basic concept is that no coordinator is needed for the nodes to work after the initial configuration. There must not be a single point of (catastrophic) failure. And obviously no "cloud" (hence ClearSky) service is needed either: you, and only you, decide if/when/which data can exit from your network!
