Domonode
About the Domonode PCB
Domonode is an open source ESP8266 PCB design by NdK73, published on GitHub under the MIT license. It is a 2-layer board, with 47 components from 18 distinct parts.
Its main chip is the ESP-12, from the ESP8266 family. Other key parts include the HLK-PM01 and AMS1117-3.3. By type, the board carries 17 resistors, 9 connectors, 4 ICs, 4 transistors, 3 jumpers and 3 capacitors.
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!

Domonode: common questions
What microcontroller does the Domonode use?
The Domonode is built around the ESP-12, from the ESP8266 family.
How big is the Domonode PCB?
The Domonode has 2 copper layers and is 1.6 mm thick.
How many components are on the Domonode?
47 components, from 18 distinct parts. The full bill of materials is listed on this page.
Where can I download the Domonode design files?
From the NdK73/HomeAutomation repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Domonode design in my own project?
Yes, under the terms of its MIT license, which NdK73 chose for the repository.
Can I test firmware for the Domonode without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP8266 firmware against it before you order a PCB.
