    Lightbulb 10 pin ISP connector really required?

    Hi

    Lately, wondering, do we really require the 10 pin ISP connectors on programmers?

    How many people really use them?

    We are developing a dirt cheap programmer and were wondering if we can take off this part to save further costs.

    Give us your views.

    I think its not required , as most people in India are DIY and use a simple male headers to connect programmer to their board.

    Or maybe we can have something like - http://www.ladyada.net/make/usbtinyisp/ , just cables coming out ... cuts cost.

    But i think that cheap 6 pin connector should also suffice. Saves me 20 bucks .

    Assuming you are working on AVR!! here is my input:

    I have used and insisted our customers to use 6 pin header as its simple for connection. See any of our board, all have 6 pin connectors in sequence of Vcc, GNd, MOSi, MISO, SCK, RST.

    The cost of 5x2 male conenctor + 10 pin flat cable and the cost of 6 pin male header & the 6 pin female to female cable goes almost same.

    The 6 pin connector is simple to use & design.

    The 10 pin connectors has advantage of "stable" and "long life" cable as compared with 6 pin.

    Still personally I prefer 6 pin over 10 pin. As it saves the PCB space.

    @vikas: soldering the cable to PCB is not simple and its time consuming too.
    8051, AVR, PIC Development Boards & Programmers and much more starts from Rs. 10 onwards @ www.deccanrobots.com

    Those connectors seem to be the most sturdy ones and still compact.
    The same applies to the FRC cable that goes with it.

    But then again it depends on what you are comparing it against.
    What is the alternate you have in mind ?

    I have yet not broken my 6 pin connector of my college time programmer i built ( 6 years now ) . But I found that FRC cable header which i had for another programmer , broke easily when i was trying to remove it.

    We can always provide the 6 pin to 3x2 or 5x2 converter cable , and itll be much cheaper.

    So for now i think 6 pin connector will be better deal.

    Exactly, a 6 pin connector is the more cost effective and logical choice for me too.

    The 6pin Relimate connectors are pretty good.
    But you may have some intermittent connection problems after extensive usage ( connect - disconnect cycles) as the female header pins expand. This happens due to the violent shake-bend-yank method employed by impatient users.

    The cure for this socket-fatigue will be to remove or cut off the lock flap in the female.
    Now, its upto the USER to ensure correct polarity......
