Where to buy JST 3-pin battery connector / batteries?

Official Hardware Nicla Family Nicla Vision

Hi, as far as I can tell your online shop does not sell LiPo/LiIon batteries or connector cables for the Nicla series. Searching for "JST 3-pin 1.2mm pitch" (as it seems to be called, from https://docs.arduino.cc/hardware/nicla-vision/#tech-specs) on e.g. Distrelec or Mouser, does not bring up anything. Are there other sources you'd recommend? Kind regards, Thomas

Amazon, Aliexpress are my two favs. It did take me a while to locate those tiny buggers though.

Do you happen to have a link to a seller or a better query term? Kind regards, Thomas

amazoning "lipo 3pin" --

and then you start looking through all the "Based on your recent views"

'JST' has become synonymous with "little dinky battery connector", whether or not this or that really is JST product.

5

I will have a look, this is the very tiny lipo battery to board connector yes?

You can go back through your amazon orders several years.

Thanks for all the links. Some are not 3-pin, others are different pitches.

In the meantime I found this:

the manufacturer part number of the battery connector is BM03B-ACHSS and its matching receptacle manufacturer part number is ACHR-03V-S.

Searching for "BM03B-ACHSS" on Mouser leads to these (automotive) parts:

(data sheet https://www.mouser.ch/datasheet/2/564/JST_BM03B_ACHSS_GAN_ETF_LF_SN_eACH-3480558.pdf )

And "ACHR-03V-S":

(data sheet: https://www.mouser.ch/datasheet/2/564/eACH-3476850.pdf)

Which seem to match the receptacle of the Nicla Vision:

You can buy the housing and wires separately at Digi-Key or Mouser.
Scroll to the bottom to see the associated wires with contacts

That is the part on the board, you need the mating part.

Thanks. Not sure which part is which on Mouser. Updated post to include both.

Now I'm also confused. Which part do you want, the part that is on the board or the part that plugs into the part that is on the board?

15

Your (DigiKey) link has a good picture. I do need "ACHR-03V-S" on the battery side.

Guess (as you write) I'd also need wires with contacts or a crimping machine.

Or buy, e.g. JST ACHR-03V-S | Lithium-Polymer-Akkus.de

If you also need a battery, then that would be the way to go.
Have fun with your project.

Ended up ordering at DigiKey (455-2198-ND, 455-3345-ND). Thanks @jim-p for mentioning the wires. Despite the small size it's quite easy to assemble them by hand.
