From the project
Schematics and files for MoaT IoT things
This is the collection of files for the physical side of MoaT: Schematics and layouts (kicad), Enclosures (OpenSCAD).
++++++++++++++++ Up-to-date stuff ++++++++++++++++
Controller and module for battery management.
The hardware design supports both active-high (diyBMS) and active-low (MoaT) serial connections.
Random stuff (Enocean adapter, USB intercept, …).
The proc/ directory contains CPU boards, i.e. things that have a bus plug.

Base heating: common questions
How big is the Base heating PCB?
The Base heating measures 40.7 × 43.4 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Base heating?
27 components, from 19 distinct parts. The full bill of materials is listed on this page.
Where can I download the Base heating design files?
From the M-o-a-T/moat-hardware repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Base heating design in my own project?
The repository has no license, so all rights stay with M-o-a-T. Use it as a reference, and ask the author before reusing the design.
