What is a solderless breadboard?

A breadboard is a reusable board with rows of spring-clip sockets on a 2.54 mm grid. Components and jumper wires push straight in, so a circuit can be built, changed, and taken apart without soldering.

What are JST connectors?

JST is a connector maker whose small wire-to-board families — SH (1.0 mm), ZH (1.5 mm), PH (2.0 mm), XH (2.5 mm) — are the standard plugs on sensors, batteries, and dev boards. The letters name the series and the pitch between pins; a harness must match both.
