Lookalikes and how to tell them apart
It looks like a 4-pin JST PH, but it has a latch (the cables are sold as “buckled”) and it doesn’t mate with PH. Adapter cables exist to Qwiic and to 2.54 mm pins.
| Connector | Pitch | Latch | Per contact |
|---|---|---|---|
| Grove | 2.0 mm | yes, a tab to press | — |
| JST PH | 2.0 mm | no, held by friction | 2 A |
| JST XH | 2.5 mm | no, held by friction | 3 A |
Before you plug it in
Crimp terminals need the crimper die made for their size: pliers crush them and the contact works loose. Housings and terminals of different series don’t mix, even at the same pitch.
The current rating is a maximum per contact, at the wire size the maker states. With thinner wire, or with every contact carrying current, stay well below it.

Frequently asked questions
What is the pitch of the Grove connector?
2.0 mm between the centres of two neighbouring contacts.
