The I-Type version is the most commonly used style for general electronic projects. It offers a compact profile and is ideal for breadboard circuits, prototypes, and battery replacements.

---

T-Type Battery Snap

The T-Type design provides an alternative mounting orientation, making it suitable for applications where wiring direction or enclosure space is limited.

---

DC Plug Version

The DC barrel plug version allows a 9V battery to power devices equipped with a standard 5.5 × 2.1 mm DC input, eliminating the need for soldering and making it ideal for portable testing or temporary power supplies.

---

Designed for DIY Electronics

These connectors are compatible with a wide range of embedded development platforms and accessories.

For battery-powered Arduino projects, they pair perfectly with our Nano V3 CH340 Development Board, providing a simple portable power solution. If your project also includes sound playback or voice interaction, our DFPlayer Mini MP3 Module and 40mm 8Ω Speaker integrate seamlessly to create compact battery-operated audio devices.
