Is this like the Raspberry Pi

 Funding Unsuccessful

We live in the world of technology. There are wide opportunities provided for anyone to create their own automatic system very easily by themselves — using boards such as open-source Arduino, Raspberry Pi, the boards from Intel and so on.

And now, we are going to introduce you to yet another type of development board.


To start off, we would like to show you a project made using Arduino:

What’s wrong with this project?

  • Crossed messy unreliable wires
  • Too many extra modules that make it confusing to use
  • Not enough ports for buttons, LEDs, display and so on
  • Wastes a lot of time and action to work with it
  • Useless if it is not programmed

There are other development boards which have already solved these problems, but they are usually so big and confusingly hard to use that connecting thousands of wires correctly would be difficult. Besides, connecting every item to a microcontroller and operating them simultaneously would be almost impossible to do.

You see, there are a lot of things you wouldn’t want. So let’s forget about the old development board.

Introducing tuBoard!

We are glad to introduce the future of development boards. tuBoard is a small but powerful board that has many features and is easy to use. It will make your project more reliable, arranged, and smart. Besides, it will make your actions easier and save you time.

Why is tuBoard so special?

There are three answers to this question:

So now let’s begin with the first answer: Pair of µControllers.

Most of these kinds of products have only one uController, while tuBoard features two uControllers: modeled after the human right and left brains. They co-operate separately — while connected to each other, with only 4 pins. Data is transferred through SPI serial communication.

One of these is the main controller for users, which they can program however they want. As you know, open-source Arduino has many libraries and is very easy to program. So we have chosen it as the main controller, to create tuBoard. And the other one has already been fully programmed by us, which means users don’t need to program it themselves. We call it “tuController”.

Why do we need tuController?

Users need to use such things like buttons, switches and LEDs in order to make their project well-operating and easier to use, and also for debugging tasks. Normal development boards are complicated to use, causing you to waste a lot of time. They also usually lack ports for connecting modules.

tuController controls over 9 kinds of peripherals — starting from buttons to the OLED display connected to it. You have full control when using tuController and everything connected to it by Arduino nano, through only 4 ports. Furthermore, tuController makes the board capable of having awesome software features. It can do actions individually, even if Arduino nano is not completely programmed.

tuController works automatically as a MAGICAL SUPPORTER for your project, which means it will save you work and time; it also will help you spend your precious time focusing on the main features of your project.

A great looking red board which is symmetrical and perfectly shaped to look at. It is well-organized, and every item is located in the perfect place.

As you can see, there’s no possible waste of surface are on the board. The board measures only 92X50mm, which is smaller than a size of one eighth of A4 paper.

Let’s have a look at the board in 3 parts:

1st part: tuController and items connected to it

  • tuController
  • Buttons × 4 – Up and Down and A, B buttons
  • Potentiometer × 3 – Three rotary potentiometers (RP0, RP1, RP2)
  • LED × 3 – Green, Yellow and Red LEDs
  • MicroSwitches × 3 – three microswitches
  • Buzzer
  • 0.96 inch OLED display – 128×64 pixel
  • BatteryMeter – Sensor that checks if the battery is full or low
  • Motor enable, fault indicators – Indicators showing the motor’s enable and fault

2nd part: Arduino and items connected to it

  • Arduino nano
  • Motor driver × 2 (2А) – Dual motor driver with 2A per channel
  • Analog ports × 8 – A0-A7 analog ports
  • Digital ports × 2 – Some digital ports
  • I2C, UART – Serial communications
  • Mot Con – Ports of additional motor driver

3rd part: Some extra things

  • Power on LED
  • Motor indicator LEDs – Motor indicator LEDs show what the outputs are doing even when no motor is connected
  • Resettable fuse on Motor power
  • Terminals for motor connection
  • The terminal of power
  • Power ON/OFF switch

Here’s how small things can contain many things when arranged. Also having a 3.5mm fitting hole in each corner makes it possible to mount on it whatever you want. It’s guaranteed that your project will become more reliable and most of all, portable and organized. All of these are controllable with just Arduino nano.

And now, let’s check out tuBoard’s feature packed program library.

Arduino Library

tuBoard has its own Arduino IDE library that provides you with the easiest way to program. In other words, users don’t need to write codes for SPI, find out bits of the address and do more pointless things,  just to turn on a yellow LED, for example. All they need to do is to write one line of code: LEDY(1);

This library can be used to control all peripherals, in which the motor driver is included too.

Program of tuController

tuController has a phenomenal program that works just like a mini operating system. And it cooperates well with the Arduino library to become a whole system.

OLED display and Up, Down, A, B buttons are used as USER interface

It has 3 main functions:

Programs – Select and run one of the programs written on Arduino nano. One of the coolest things is that you can import up to 3 different types of programs you have written, and choose one to work on.

tuBoard is easy to program, enabling you to write shorter and more efficient code so you waste less work and time. In the pictures below, two programs are running: The first program turns on a green LED and the second turns on a yellow LED.

Check Mode – Check the progress of items on the board, even when an Arduino program is not running.

And now, let’s check it out.

Digital, Analog Pins – Connect distance sensors to A0 port and then select Arduino’s Digital, Analog Pins from the check mode.

See, we can see the sensor value without even writing a program to show the value.

Output Peripherals – LEDs, RGB, Buzzer, Motors

Other – Other settings

Setting for the battery indicator that shows if the battery is full or low. Also included is emoji support, which makes it more fun to use.

For whom?

All of these features described above make development more efficient, so that you have many advantages. Easy development means easy to use, for beginners and experts as well. Anyone who is into programming will enjoy using tuBoard.

For what?

You can use tuBoard for many types of electronics and robotics projects. You can be sure that your project will become easy to use, smart, small, and interesting — which will make you feel satisfied using tuBoard.


Risks and challenges

tuBoard has been developed for long time since the initial idea had found. it has tested starting from hardware to software. When it comes to manufacturing, we are working with a PCB prototype service that manufactures products in high quality.

It is not an intellectual idea, its beta version has already established which means tuBoard has gone through every batch of production so that the risk reduction have been made.

We are glad to introduce the future of development boards. tuBoard is a small but powerful board that has many features and is easy to use. It will make your project more reliable, arranged, and smart. Besides, it will make your actions easier and save you time.
