Overview

Labview 2 is an open-source printed circuit board by miautort, from the miautort/PCB-Shark repository on GitHub, published under the MIT licence. It is a 2-layer board of 98.3 × 96.5 mm with 29 parts on 30 nets, routed with 184 tracks and 3 vias.

It is built around the MSP430G2553IN20 and TLV1117-33DCY. Its parts include 12 diodes, 7 resistors, 3 capacitors, 2 ICs and 2 connectors. It belongs with the MSP430 boards of this library.

This is a simple project given as an assignment. The conditions were for the board to be within 100x100mm, and to use the specified microprocessor.

The task itself was to draw something with LEDs. As just placing some LEDs was just boring, I decided to make it interesting through shape as well, and use the components themselves to make it look better. The rat with pink bow meme exploded just about in time to inspire me, so here we are, with a shark with a pink shiny bow.

Here's the component list:

ComponentNumber and/or Type
MicrocontrollerMSP430G2553IN20 (U1)
LED12* ; both 3mm and 5mm are compatible
Capacitors1x1nF (C1) ; 1x10uF (C3) ; 1x22uF (C2)
ConnectorsMicro-USB for power (J2) ; 4-pin for programming (J1)
Resistors1x100kOhm (R1) ; 6x330** Ohm
Quartz Crystal32kHz (Y1)
Voltage RegulatorTLV1117-33 (U2)

*I used 10 pink for the bow and 2 blue for the eye

**The resistor values depend on the chosen LED color

Questions

How big is the Labview 2 PCB?

It measures 98.3 × 96.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Labview 2 use?

29 parts, built around the MSP430G2553IN20 and TLV1117-33DCY. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Labview 2 KiCad files?

From the miautort/PCB-Shark repository on GitHub, at the commit this page was made from: the board is labview 2.kicad_pcb and its schematic labview 2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Labview 2 design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
