============= MoaT Hardware

This is the collection of files for the physical side of MoaT: Schematics and layouts (kicad), Enclosures (OpenSCAD).

++++++++++++++++ Up-to-date stuff ++++++++++++++++

---

BMS

Controller and module for battery management.

The hardware design supports both active-high (diyBMS) and active-low (MoaT) serial connections.

---

Wire

Connect some wires to the MoaT board.

---

misc

Random stuff (Enocean adapter, USB intercept, …).

CPUs

The proc/ directory contains CPU boards, i.e. things that have a bus plug.

CPUs are responsible for adapting 1wire (5V) and MoaTbus (12V) to their internal voltage.

Boards

The board/ directory contains everything that has a bus socket, i.e. interfaces to the Real World.

Many of these boards have 12V-MoaTbus, 5V-1wire, and/or 3.3V-I2C connectors.

The boards are not responsible for translating voltages to the (commonly) 3.3V which CPUs expect.

Breadboard ++++++++++

The most important part. Use this to test CPUs.

Heating +++++++

This board has two transistors to switch one or two 24V radiator valves (PPM).

Smoke detector ++++++++++++++

This board fits into a Gira Dual or Q smoke detector.

Old stuff

The old/ directory contains things I need to clean up.
