<p>During the months of confinement, I considered buying a printer. The quality of Prusa is incredible, and during my visit to the Maker Faire Roma I saw the new Prusa Mini. It was awesome. So I decided to order it, and it wouldn't arrive until September. But she came ahead shehe, for my birthday. Another Prusa for every birthday. 🤣🤣</p>

<h2>Upverter</h2>
<p>My friend Marta Verde has shown me another PCB design program that can be interesting. <a href="https://upverter.com/"><b>Upverter</b></a></p>
<h1><a id="adrianino"></a>Adrianino</h1>
<h2>08/09/2020</h2>
<p>Although I have already finished my Fab Academy, I am still researching. Speaking with my instructors Nuria and Pablo, I told them that I wanted to continue working on the <a href="https://gitlab.fabcloud.org/pub/helloworld/index"><b>Hello World project,</b></a> but I was not satisfied with making a board for each sensor or actuator.</p>
<p>So I decided to make a board with the ATtiny1614, where I could use the maximum pins for the inputs or outputs; that had external power; I2C connection. The idea is that a student can test as many sensors as possible, become familiar with electronics and programming little by little. And the <a href="#adrianino"><b>Adrianino</b></a> was born.</p>
<p>Furthermore, I wanted to go one step further and place a VCC pin next to the UPDI programming pins, which I will explain later on how it works.</p>
<p><img src="images/week06/week06.37.jpg" width="80%"; max-width="700" /></p>
<h2>Features</h2>
<ul><li> This board has FTDI and <b>UPDI + VCC</b> connection to program it without the need for external power (or the FTDI).
<li> It contains a voltage regulator to power the board with a <b>power supply</b> (9V battery).
<li> It has another 9V power connection to for example power a DC motor driver.
<li> Then there are 4 outputs or inputs with VCC and GND on each side to be able to connect different inputs or outputs.
<li> On the left there is an <b>I2C</b> connection to connect an LCD, OLED or a sensor that uses this communication.
<li> There are 3 outputs or inputs at the bottom and with a GND pinout.
<li> There is an LED and an integrated button, which will help us to test that the microcontroller works with a simple program.
<li> Through the FTDI connection we can read the data from the different sensors through the Serial.
</ul>
<h2>BOM and Schematic</h2>
<p>This is the schematic where you can see all the components.</p>

<h2>Board design</h2>
<p>In the files section you can download the Eagle files and the PNG's. Here is a sample of the PNG's, traces and cutting lines.</p>
<span class="image main"><img src="images/week06/week06.39.jpg" alt="" /></span>
<h2>Programming</h2>
<p>The new generation of ATtiny's are programmed through <b>UPDI</b>, for more information on the process you can follow my documentation of the week <a href="week08.html"><b>Embedded Programming.</b></a></p>
<h1>UPDI + VCC module</h1>
<p>At the time of programming, until now I used the Hello USB-serial.FT230X + Hello serial-UPDI.FT230X and also the power supply of the board with an FTDI (which later helps us to read through the Serial).</p>
<p>With this adapter we have the Serial + UPDI + VCC adding a higher pin, without the need to use another FTDI to power the board.</p>
<span class="image main"><img src="images/week06/week06.40.jpg" alt="" /></span>
<h2>Schematic and board design</h2>
<p>The design is the same as the one <a href="http://academy.cba.mit.edu/classes/embedded_programming/UPDI/FTDI-UPDI.png"><b>Neil uses,</b></a> except that I add the Vcc pin to power the board that we programmed.</p>
<p><img src="images/week06/week06.41.jpg" width="30%"; max-width="700" /></p>
<p>In the Files section you will find the PNG's and the Eagle file to download them.</p>
<p><img src="images/week06/week06.42.jpg" width="70%"; max-width="700" /></p>
<h2>Operation</h2>
<p>The connection is very simple, we only need the FTDI-USB and we connect the UPDI + VCC module to the board, in this case to the Adrianino that has the three pins (UPDI + GND + VCC).</p>
<p><img src="images/week06/week06.43.jpg" width="70%"; max-width="700" /></p>
<p>In the following video you can see the programming process of the Adrianino and an LCD.</p>
<p><iframe src="https://player.vimeo.com/video/457496735" width="100%" height="360" frameborder="0" allow="autoplay; fullscreen" allowfullscreen></iframe></p>
<h2>Conclusions</h2>
<p>With this evolution, we managed to program through UPDI without the need for external power from another FTDI.</p>
