29
+**JST** stands for **Japan Solderless Terminal**.
30
+It is a Japanese company that manufactures a wide variety of electrical connectors used in consumer electronics, automotive, industrial, and hobby applications.
31
+
32
+## Key Points
33
+
34
+- **Company**: JST Mfg. Co., Ltd. (founded 1957, Japan).
35
+- **Products**: Electrical connectors (board-to-wire, wire-to-wire, board-to-board, IDC, FFC/FPC, etc.).
36
+- **Famous series**:
37
+ - **JST-XH** (2.50 mm pitch, board-to-wire)
38
+ - **JST-PH** (2.00 mm pitch, board-to-wire, very common in LiPo battery packs)
39
+ - **JST-SH** (1.00 mm pitch, used in drones and compact electronics)
40
+ - **JST-SM** (2.50 mm pitch, wire-to-wire, common in LED strips)
41
+- **Why popular**: Reliable, compact, standardized, and with secure locking features compared to generic “Dupont” connectors.

61
+The **JST SM series** is a common wire-to-wire connector, often used in LED strips, RC electronics, and low-current applications.
62
+
63
+## Key Specifications
64
+
65
+- **Series**: JST SM
66
+- **Type**: Wire-to-wire, single row, housing + crimp terminal
67
+- **Pitch (pin spacing)**: **2.50 mm** (not 2.54 mm)
68
+- **Current rating**: ~3 A (per pin, typical)
69
+- **Voltage rating**: ~250 V AC/DC
70
+- **Number of positions**: 2–12 pins available
71
+- **Locking mechanism**: Positive latch (prevents accidental disconnect)
72
+- **Wire gauge**: AWG 22–28 (stranded wires, typical)
73
+- **Mating cycles**: ~30 times (not a high-durability connector)
74
+
75
+## Important Note
76
+
77
+- Many vendors (especially on marketplaces) mislabel it as **“2.54 mm”**, but **the official JST specification is 2.50 mm pitch**.
78
+- Since 2.50 mm ≈ 2.54 mm, people often confuse them, but they are **not guaranteed cross-compatible** with other 2.54 mm systems (like Dupont, KK254).
79
+
80
+## Summary
81
+
82
+- **Correct spec**: **JST SM 2.50 mm pitch**
83
+- “JST SM 2.54” is just a common mislabeling.

+The SparkFun Qwiic connection system utilizes a `1.0mm pitch`, 4-pin JST-SH connector. These connectors are specifically designed to be tiny, polarized (meaning they can only be plugged in one way), and reliable, making them ideal for quick, soldering-free I2C prototyping.
