Trapezium One

Trapezium One - Low cost redundand node for IoT


Towards a More Smart Thing

for Automation in the Internetwork



Besides its complexity, the dimension of Trapezium One is set to 33mm x 25mm

The same of a common Xbee PRO.

The Brain of Things (BoT) in the Internet of Things (IoT)

BoT concept and acronym add an important feature to those interconnected and automated Things,

for the interpreters involved, running on top of a real-time and multithread Full-POSIX RTOS Apache NuttX or in future our forked Alcor OS, the power of functional languages or languages used for artificial intelligence (like F# or LISP), while supporti concurrently very popular languages like C#Micro-Python, Lua,, Javascript . Source-Atoms sharing data sets talking at various speeds and media and interconnected (Ram, Flash, SPI, RS485, Wireless or distributed over iternet via standard networking, SDNS and MQTT protocol) for all kind of etherogeneous work or automations construct (not all building material are the same or for same purpose) done with different parts in a whole.

The supported interpreters include the forgotten Forth

still interpreted and dynamic but so powerful with the algorithmic speed of compiled C. Forgetting binary or keep it marginal, as it is for the (not obfuscated) Web. If not the base firmware. - Extending a node binary proof. menas: make it dynamic, responsive, changeable and never fixed. -- involve incremental and interactive programming in control, deployment, observation of a running system, a new way to development process or editing, deployment of small and large automations, with editing flow based using IBM NodeRed forked General Node integrated with many of good concepts that Symbolics Genera or Lisp machines had, in One harmonized, extended, simplified form. Dissipating complexity downsides and failures.

- Some make on it to depends the stability of the automation, systems small and big, wich is wrong. All should run independently at a single node level, or even inside it, on a bed of a powerful RTOS Like NuttX. Inside a node, a bunch of them wired, as a thousand involved locally or distributed over IPv6.

Relying on low cost, reduntant (even A+B ISPs or WAN) Gateways... (read well) not _concetrators_, for a strong, secure and fail safe distributed automation. Of course if some of the distributed automation is over a network, a gateway is a must. So we use it! with a full featured GNU/Linux OS (without to reinvent the hot water), Mosh or an advanced SSH tunnel, as interface for nodered, a fork of it, an hybrid with many genera concepts built in, that solve a lot of security problems to put hands on what behind that gateway as nodes so tiny that could not be hog with control or editing interfaces, so with that, make it in simplicity and where it not harms and is obvious more resources as a way to access is located.

- The Hardware:

Trapezium One, Avior32 as production boards, ESP32 and Mizar32 as Educational/Development kit.

Supported add-in cards & Headers:

Trapezium One support 1x MikroBus-Clickboards stacked

in the extension sockets (or more depending the add-in board how is done), other connections are handled via USB Type-C headers or the rear 40 pin rear connector.

The Type-C is a very well done and cheap connector, it solved also the problem since have let us to concentrate USB many signals, as well as full redundand RS485 20Mbit bus (easy translable in differential fiber optics) all over 1 single connector. I2C, power in and out, as it is important and omnipresent.

Wired Networking

RS485 (redundant half duplex) - Copper wires  optional(simple)

external SC/ST adaptor for Fiber Optics (Tao Fiber technology).

Wireless Networking

LoRa modules, over MikroBus. (LoRa PHY was fully decyphered, Here)

Trapezium One Specs:


Concept not completed, as soon as completed

we will pass to some demo boar d creation.


Research Path in SW & HW

with Sub and Meta projects:

This Demo Board is connected with the Sagittarius Sub-Projects Alcor OS, and Mira Spiralcity,

its distributed Automation PiAutos - World Wide Distributed and decentralized Automation. 

Valid for IoT in general, Robots, Home automation, Industry, Smart city, and Internet

"turn the PWM rotor in Japan, and close the Niagara Falls main valve"

With an extensive use of IPv6, Secure DNS database, never done before.
