Description: This is a 2-pin, through-hole PH series JST connector. The pins are spaced by 2mm.

We really like the solid locking feeling and high current rating on these small connectors. This connector will mate with all of our LiPo batteries.

  • Beware! This part is in the SFE Eagle library, but it’s poles are switched! Luckily I could just put the connector on the other side of the PCB.

  • I agree, I don’t see this in the SFE library.

    • Look in SparkFun-Connectors/M02. There should be several versions in there marked PTH-JST.

      Also note that the “+” in the Eagle schematic editor is the part’s origin point, NOT the positive terminal (all parts will have that somewhere). In the PCB editor, if you turn on the tdocu (top document) layer, you’ll see positive and negative marks. These aren’t in the schematic editor because M02 is a generic two-pin connector. We’ll consider splitting it out and giving it it’s own schematic symbol.

  • Where can I find this one in the Eagle library?

    • Did you ever find it?

      I looked in the right section of the Sparkfun library I installed but I don’t know if I’m looking at the SMD, vert or right angle one (this one).

  • The poles aren’t switched, you are just mistaking the little “+” handle used for moving the components for a “positive” marker. I’ll agree that’s pretty confusing though!

    • Well, yes it is really confusing. But I see your point. If that is not the sign to indicate which is positive then there is nothing to indicate it. I’m hoping it’s your not supposed to check the layout to know if you have made the schematic correct? Some sort of indication for the positive terminal would be nice.

      • Turn on the top document layer in EAGLE. There is a notation there for positive and negative (at least for all the batteries and pigtails we carry).

  • This part doesn’t seem to be in the new Eagle library. I tried copying the one from the charger board.
    *edit: wrong, I just copied it to the wrong place. Whoops!

  • what is the part number on digikey?

  • I’m sorry but the datasheets for all of these connectors are wrong.

    • The datasheet covers this part’s whole family with different numbers of pins. For this particular one, refer to the “pole” table on the right-hand side, and find the two “pole” (pin) version.

  • Is this the same one that’s on the EL Sequencer? Based on the pictures, it looks slightly different.

    • The one used on the EL Sequencer is the surface-mount version of this connector, but as far as plugging things into them they’re 100% compatible with each other.

  • Is the corresponding plug also available separately (ie w/o attached wire)?

  • Is there an easy way to fix the EAGLE part? As Jonas pointed out, the poles are switched

  • Is this connector breadboard compatable?

    • Yes and no, the pins do fit into a breadboard, the pitch is correct. Problem is the leads are not very long and small diameter. They fit very loose into a breadboard. These are meant to be soldered ;-). They will fall out if your moving the breadboard around or have any vibrations. If your breadboards not moving and your doing some temporary testing, these work fine.

      Sparkfun, in the future can you find a slightly different version that has slightly bigger diameter and longer leads?
