M10-CUBE community project is a Practical Form Factor Ecosystem. It is the idea of a micro controller cube 10x10x10 cm. It is a hardware agnostic cube.

Only one rule must fulfilled to say that this is an M10CUBE device:
- External enclosure (CUBE) maximum dimensions X = 10cm, Y = 10cm, Z = Up to 10cm . Powered by 24 DC or Battery or POE or AC (220/110).

Some sub rules must also apply but it is to verify that every M10-CUBE incarnation can communicate and stand side by side with the other.

Directives:

- Used materials and modules out of the self if possible.
- DIY friendly.
- Think Green and Reuse philosophy

PCBs, Schematics (Eagle and KiCAD), 3D enclosures and software are in constant developing.
Applications will keep coming so to encourage everyone to get involved and to use the M10CUBE out of the box

CUBEM10  road map V1.1 (M10 for the shake of simplicity)

Some history as a preface.
Despite the fact that we started M10 as a modular PLC system within a cube of 10x10x10 cm soon realized that in a broader sense, everything is a Programmable Logic Controller. Every microControler Programed Logically to help us in everyday life.
 
Many years ago back in 1980 when programming Z80 custom made designs written in assembler for controlling various machinery in reality that was a primitive PLC.
Of course later as wiki states IEC 61131  (then IEC 61131 -3) published in December 1993 PLC came to life for ladder programing. Today (initially published in 2005) the specification of IEC 61499 (as explained by Lewis and Zoitl) is one step up to  IEC 61131.
In a sense the famous Arduino Blink program is a PLC program (not in IEC 61131 -3 but in C).
PLC remains as standard word for industrial controllers. Recent days many change the term PLC into a more appropriate acronym PAC ( Programmable Automation Controller).

PAC is an industrial controller that combines the functionality of a PLC with the processing capability of a PC. You are thinking right. Is a Raspberry Pi running a PLC program called PAC?  The answer is YES.

The idea was tinkering in my mind so in 2011 in the Raspberry Pi forum I started a thread in an effort to combine Raspberry and PLC environment:
Turn Raspberry Pi into a P.L.C (Programmable Logic Controller)
https://www.raspberrypi.org/forums/viewtopic.php?f=41&t=455&hilit=vorrias
That time my Raspberry was not delivered yet.

Time went by. ..

During that time I found enthusiastic designers and they contribute to the final M10CUBE idea.
I hope to be permitted to put their names here. Without these guys M10CUBE could not be born.

It does not matter if M10 contains a PLC or a PAC or a custom made C, C++ or Python firmware. M10 likes them all. Because M10 is a controller cube, a container I may say that makes the control job look easy. Any control job.  
You may ask what hardware is inside? The answer is anything. Hardware that haven't cross our mind yet. The hardware inside M10CUBE may be different as long as the first low of M10CUBE is not violated

But we must start from something we all understand.
To get an idea of what a M10CUBE looks like we will introduce you our first M10CUBE PLC incarnation which at the time of writing ( 05/05/2020) has the following modules ready for fabrication.
1 – CPU module (contains Raspberry Pi 4). All modules share the same 40pin Raspberry bus. 2 – DIO module. Eight opto isolated 24V inputs plus eight 24V outputs high side transistors.
3 – DO module. Eight relays with 16 amps contact capability to power any heavy loads even 220V mains power appliances.

M10CUBE ecosystem in detail
The design must not violate the rule of M10CUBE:
- External enclosure (CUBE) maximum dimensions X = 10cm, Y = 10cm, Z = Up to 10cm. Electronics inside must be powered by 24 DC or 220 AC or POE, or battery.
Some sub rules must also apply but it is to verify that every M10CUBE incarnation can communicate and stand side by side with the other.

Directives:
-Used materials and modules out of the self if possible. -DIY friendly. -Think Green and Reuse philosophy
-Z dimension depends on number of modules . -within the CUBE interconnection bus between modules must exist and modules designed for the specific M10CUBE can be interchanged between M10CUBEs sharing the same bus e.g Raspberry Pi 40 pin.
-All modules belonging to the same M10CUBE type must share the shame mechanical specs for interconnection.
-M10CUBE can be connected with almost any number of other M10CUBEs by CANBUS, WiFi, Ethernet, LoRaWAN, Bluetooth, or the the upcoming standard by Amazon, Apple, Google, and the ZigBee Alliance -Out of the box as industry dictates CAN BUS is the best candidate and very easy utilized by using readily available software libraries and hardware

Why M10 name?
-M stand for modular. -Modular was chosen for obvious...

    On going is an STM32 M10CUBE add-on module. The board is planned to accommodate:

    - NUCLEO-F303K8 module. Interchangeable with Arduino nano.
    - Super-capacitor for STM32 RTC.
    - Micro SD
    - CAN transceiver chip MCP2551 or TJA1040
    - Analog I/O 10V
    - ESP8266 ESP-01 module.
    - Micro SD (common for STM32 or ESP8266. Jumper select)
    - LoRa E22-900M22S + E22-900M30S module
    - GPS NEO-7M

    Design: KiCAD.

    Time: About a month.

    If you have  have knowledge in electronic design and like to contribute on that, please let me know to be part of the team in slack. So to shorten the PCB design time.

    Next a M10CUBE sensor board is planned.
