openPicus Flyport WIFI

robotonics

I have tried to develop an application using the MRF24WB0MA Wifi module from Microchip. I had no problem building a board, however, I had huge problems unravelling code for the TCP/IP stack.

 

All code provided by Microchip is intended to be used in conjunction with the relevant daughter boards, and development kits, such as the PIC18 Explorer kit. After looking on the internet for some sample code, or a similar project that I could adapt, I found openPicus Flyport!

 

I could not afford to purchase a Flyport Wifi module for myself, and had all components needed to create one, schematics are freely available for download. Therefore I have attempted to build one myself.

 

This blog will contain details on the build of a prototype and relevant test and development notes.

    Nice looking board!  I'm trying to recall - is that particular connector used in order to connect to the PIC24 dev board?

  • I have fixed the printing problem, so the circuit could now be completed. I have purchased a lot of 47 sheets of HP Premium Inkjet transparencies on Ebay.

     

    The difference in finish between the HP and previously used Ryman Inkjet Transparencies is astonishing.  I am using a Canon MP270 Inkjet printer with  Standard / High quality / Plain Paper setting, and the results are excellent for very fine pitch IC's. So far I have managed to create a board that has a 132 pin Hirose connector, with 0.254mm traces connecting to it.

    The question now is, is it worth the effort? I think I would be wise to research wireless modules again, see if there are any new products out there.

     

    I am a little disapointed with Microchip for not making more effort with their wireless modules, does anyone else feel the same?

  • I got the Acetate back from the printers today, it was worse than the one I printed out on my inkjet. I called the printer and tried to have a conversation about what I needed, a 0.02mm gap between the 0.025mm pins on a 64 pin PIC.

     

    He talked to me about differences in printer drivers and layout software, I have never got to delve into these mysteries before, other than the installation of printer or two.

     

    Can anyone point me in the right direction?

  • Well if you ever need a board in a rush, I can make for you and post. All I would need is layout, cost would be around £5 for a 100x80mm FR4 board. Or if you need help with making your own, just ask!

    Interesting to hear about the process.  I've never tried to etch a board but would like to someday.  Batch PCB services are very affordable but the typical 3 week wait is a bummer.
