Workshop Update for December 7th, 2012

in Workshop Update by DP | 10 comments

We finalized 6 new designs and sent off a box of PCBs. Several test a new header-less programming pad we’re working on.

We researched various feeder mechanisms for pick n place machines, and posted about them. Which also provided some material for app notes.

The protoboards received another update. We added mini USB B breakouts to all of them. We’re also working on a smaller header-less programing footprint for our boards.

    Have you seen this alternative for a isp/icsp header? http://www.daniel-spilker.com/blog/2011/04/25/isptouch-for-avr-microcontrollers/

    It’s using a spring loaded “solo stacker” connector – good for just flashing new firmware onto the board but a real pain if you need hook up the board for a longer In Circuit Debugging session…

    I have two suggestions for this proto board’s next revision.

    1. Add a micro-USB footprint just in the opposite side of the mini-USB. It will be good addition.

    2. Add a place to use SMD7050/3225/6035 crystal/oscillators.

    Oh goodie! I suggested the USB somewhere else in another post, so I’ll give myself a little gold star for that LOL :D
    I’m assuming that this holes around the outside of the QFP match your other QFP-Header boards, so that we could fit a different pitch QFP if necessary by using a daughter board?

  4. Sleepwalker3 says:

    Well 0.65mm is handy too, looks like a useful board :)

  5. Sleepwalker3 says:

    Is this board likely to be available through Seeed and if so, could you give me an idea of when?
