Need Someone for a Project: Cypress PSoc6 BLE kit +  Honeywell Pressure Sensor Shield

rscasny

I was contacted by a supplier who is interested in giving hardware for free to someone who could do a project for them featuring  Cypress's PSoc6 BLE kit +  Honeywell Pressure Sensor Shield.

 

They would like the person to do the following:

 

Interface the pressure sensors of the Honeywell Sensor Shield with the PSoC 6 analog/digital peripherals and then transmit data via BLE or showcasing it on the E-ink display of the PSoC 6 BLE Kit. The project should have some kind of medical application. For example, measuring pressure in some kind of health/medical application.

 

Just to refresh your mind, here are the parts involved:

Click here for more information on this Honeywell Sensor Shield. I have not roadtested this product.

 

I would like to do this sometime in October. I'd like to get it accomplished in a month--the shorter time period is why I am not offering it as a roadtest.

 

If you are interested, feel free to comment below.

 

thanks.

    Hi Randall

     

    Well, I found a breakout board that looks good for the project.
    I found one at Adafruit that has the same MPRLS sensor and voltage regulator as well as a level shifter for the data signals on board.
    I would use this as "hello world".
    Because a voltage regulator and level shifter are included, it is easier to use than Honeywell's breakout board.

    Is this a problem to can get one as a sample kit? If not, no problem.

     

    At the Attachment there you can find the schematic and PCB for Eagle CAD.

    I thought as well for the others whether they need this.

     

    Best Regards

    Gerald

    Sorry for my silence about the breakout boards issues in these days, I followed the thread by email but It was impossible to write back a decent comment.

     

    I see two options, here. The first is designing a small breadboard with just the pins expanded to the 2,5 mm distance but as and other say it's a pain to solder the non-exposed pins. In cases like this, where the distance is not terrible but pins are not exposed I adopted a bit delicate but efficient solution, using a wire-wrapping wire to create the pins and gluing the small footprint on an isolated zone of a PCB breadboard. After this small effort, the resulting home-made breakout is almost stable and always worked fine for me. The image below shows my last try to apply this technique to a chip with a pins distance shorten than our case. I just stopped when I discovered a 4 Euro breakout board I bought the next day.

    IMHO, the best solution of ever (I think Randall can be helpful in this case) is buying pre-built breakout boards like the example below. When I lived in Fremont, CA I found plenty of these stuff with many different configurations but here in Europe I never found this.

    What about making some footprint design for a micro-production? It will cost a few dollars I think. Let me know if this has sense I can try to provide if 30 days to have the stuff ready to ship is acceptable.
