JST Right-Angle Connector - Through-Hole 2-Pin

Jargon buster

Plain-language definitions for the technical terms used above.

JST PH

A small keyed plug-and-socket connector with 2 mm pin spacing, often used for low-power electronics connections. You need the correct JST PH cable, and its current rating limits how much power should be passed through it.

LiPo

A LiPo (lithium polymer) battery is a rechargeable lithium battery widely used in portable projects because it is light and compact. LiPo cells need correct charging circuitry and careful handling to stay safe, so equipment that supports LiPo generally includes charging or protection hardware suited to that battery type.

PCB

A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.

pH

A measure of how acidic or alkaline a liquid is, on a scale where 7 is neutral. For a water monitoring kit, pH tells you about water chemistry and whether the included probe matches the range and accuracy your project needs.

through-hole

A mounting style where the component leads pass through holes in a circuit board and are soldered on the other side. Through-hole parts are often easier to handle and solder by hand, which is useful for classroom and hobby projects.
