  • The description and compatible products for this (PRT-09914) and other JST connectors in the Sparkfun Eagle Library is.....well, to put it mildly, somewhat confusing and totally inaccurate. By selecting this connector in the Sparkfun Eagle Library I assumed I would be given accurate information, such as the pitch, for example. The pitch is NOT 0.1" (as stated in the S.E.L.). The correct pitch is 2.0mm. Unfortunately, I did not discover this discrepancy until I got my boards back from the fab house and went to insert a 0.1" shrouded header that I had purchased a batch of... specifically for this project. It's really no big deal. I can use the 2.54mm headers in another project, as they are pretty much the standard for my applications, and I can buy some 2mm pitch JST headers and connectors for this run of circuit boards. I'm just wondering why the information in the S.E.L. is so screwed up where these connectors are concerned?

  • None, no and no.

  • There's one huge advantage the 20M2 has over the 20X2....two words..."parallel tasking".

  • I've been meaning to buy some wire strippers for small gauge wire for quite some time, but I just couldn't bring myself to pay $30 or more for a tool that only strips insulation from wire, as I can consistently strip as small as 26 gauge wire with regular wire cutters. I was skeptical about these being able to strip 30 gauge, especially given the price, as you usually get what you pay for, especially when it comes to tools. A $5 tool usually equates to a waste of $5, but not in this case, these little strippers are fantastic. If you need an inexpensive small gauge stripper that actually works as advertised, this is the best $5 you'll ever spend.

  • I don't see how you could be having a connection jumping rows on you like that (i.e. getting a connection where there shouldn't be one). It's basically just four 600 tie-point boards connected together with 5 pwr rails. Do they not have the double sided tape on the back of them? There would have to be something broken for two rows to get cross connected on the inside Man, if that were to happen on a power bus you could fry your chip.

  • Which specific ICs are you referring to? I'd like to try that trick myself?

No public wish lists :(
