Leave a reply Breakout Board Progress! The breakout board for the memory LCD has been made! There were a few delays getting the screen to match the requirements of what our university wanted, hole sizing, track widths and spacing. At the bottom of this post I will post the gerber files and a link to a fantastic website to view them on. Why do we need to do this again? As I explained briefly in my last post, we need a breakout board for this screen because of its connector type. This particular LCD has an elastomeric connector which cannot be soldered to, this meant that until we could actually hook up the microcontroller to the display we needed some way fo connecting wires to it, without solder… ZEBRA Connectors Elastomeric displays are designed for machine assembly and not hand assembly. To create the connection between the display and PCB you simply put the correctly size ZEBRA connector onto the PCB and then place the screen on top, making sure that the displays conductive pads line up with the circuit board underneath.

They are a common item in electronic projects and enable easy, clean installation of electronic devices. The image at right shows a simple DB25 breakout circuit board from Winford Engineering. The breakout board is positioned between your computer or indexer and the motor drivers and serves two purposes in the CNC control system: Your wiring schematic would look something like the following:
INA Breakout Board Hookup Guide Take a look at the schematic, and you will notice that the breakout board consists of a shunt resistor (R), the INA chip, and an output resistor (R). While R and R might appear to have 2 resistors, only one is populated on .
That means i can can now hookup everything at once, finish the alarm clock software and publish the lot. More details to follow After studying the schematics and DS pinout, I made a breadboard sketch in Fritzing, tried it out and transferred the design to a small piece of stripboard. The usual pitfalls were encountered; a broken IC socket had to be de-soldered and replaced and I reversed the polarity of the coin cell holder.
But I did end up with a functional ‘breakout board’ I can use in other projects. And I reckon a small side-step like this can only help in developing the skills needed to tackle a big project. I decided to make a new revised board, with proper pin headers and an activity indicator LED. This output is enabled by writing 0x10 to the DS control register 0x The lower two bits control the frequency of the square wave and the default value of 0b equals 1 Hz, causing a slow blinking LED.
Changing the register to 0b will set the frequency to Hz which produces a nice steady glow. Musically inclined readers will have noticed that Hz and Hz are solidly within the audible range for humans. Or you could disable the SQW output and switch it on when a certain condition, like reaching a certain date or time, has been met

The other is to connect a 5v DC power source to the DC in terminal block labeled as Item 1 in the parts overview. With DB25 parallel connector facing to the left make sure the input selector switch is pushed over to the right. Make sure you have a Positive Red and a Negative black wire. It is highly recommended you use the correct wire colours for each step, this will avoid confusion at a letter stage.
Strip the insulation off each of the wires back 6mm approx and give each wire a twist to bind all the loose fibers together. And insert the stripped “Negative” Black wire in to the terminal marked “5V-” on the terminal block. Tighten both screws on the terminal block. The next step is slightly more complicated as we don’t know the actual length of wires needed to connect the JK02 Breakout board to the 5v DC Converter as everyone’s enclosure will be different.
So we are going to have to measure them by running them from the JK02 Breakout board to the Converter. Allow the surplus wire to hang over the top or back or top of the converter. With the wires now run to the DC Converter, allow another mm of wire as a stripping allowance and cut off the remainder.

Try It If you want to give Breakout a try, gather an Arduino or other compatible board , a button, an LED, a couple of resistors 10k for the button and something between ohm and 1k for the LED and a breadboard. Wire up the LED and Button.
This breakout board, based on the best-of-class Si, is an all-in-one stereo audio FM transmitter that can also transmit RDS/RBDS data! Wire up to your favorite microcontroller (we suggest an Arduino) to the I2C data lines to set the transmit frequency and play line .
If you just want rotation in a single direction, you can leave DIR disconnected. The chip has three different inputs for controlling its power states: For details about these power states, see the datasheet. The default state of the ENBL pin is to enable the driver, so this pin can be left disconnected. Note that the carrier includes a 1.
Current limiting To achieve high step rates, the motor supply is typically much higher than would be permissible without active current limiting. The DRV supports such active current limiting, and the trimmer potentiometer on the board can be used to set the current limit. One way to set the current limit is to put the driver into full-step mode and to measure the current running through a single motor coil without clocking the STEP input.
The measured current will be 0. The ref pin voltage is accessible on a via that is circled on the bottom silkscreen of the circuit board. The current limit relates to the reference voltage as follows: The coil current can be very different from the power supply current, so you should not use the current measured at the power supply to set the current limit. The appropriate place to put your current meter is in series with one of your stepper motor coils.

Capable of 27 colour combinations and controllable from either a GUI or the command line, it can also perform patterns. Small board which connects directly to the GPIO header, Light up your case to suit your mood or display status information. The board has been designed to fit directly on top of the RaspberryPi similar to the HAT physical specification. Also available as a bare PCB – ideal for school projects and anyone wanting the extra challenge of soldering some hardware for their Raspberry Pi.
The kit includes a pre-prepared strip-board, all the necessary components and cables, and a very complete full-colour manual with lots of code examples.
Breakout Boards. Breakout boards are a common electrical components that take a bundled cable and breaks out each conductor to a terminal that can easily accept a hook-up wire for distribution to .
Currently I have one built on a weird protoboard I bought from RadioShack. Then for the Photon 3. Well this circuit works as it should but I have a feeling it won’t be great as a stand alone setup. I managed to get it working on an Arduino also although I think I toasted the Arduino because it won’t work anymore. Which is weird because my oscilloscope still shows a data waveform but no LEDs are lighting up when instructed.
Anyways, all this fussing about with this clunky board has led me to develop a PCB in which I want to have made. But just before I pull the trigger on that I wanted to read the datasheet again and really make sure I’m getting the most of Rev 1. It’s not great by any means I know. So here begins my questions which I hope you all may be able to talk some sense into this project.

Just because the stripes are in a certain order doesn’t mean the resistor has a direction! Resistors are the same forward and backwards, it doesnt matter which way they are used. Highlight the text below to see the answer Red – Red – Brown – Gold What is the value of this resistor? Highlight the text below to see the answer Ha! Trick question, it is not possible to put a resistor in ‘backwards’. They work either way! Say hello to the LED! We’ve had some time with the LED already, but lets get to know her a little better.
The light-emitting part, well, that makes sense.
