Description

Technical Overview

The LilyPad Coin Cell Battery Holder CR2032 Battery Mount Module provides a compact power solution engineered specifically for sewable electronic ecosystems. The board houses a single 20mm coin cell battery, providing the necessary operating voltage for low-power microcontroller systems and peripheral hardware. Notably, a small slide switch is installed directly onto the board in-line with the electrical power trace. Consequently, this integrated switch allows users to shut off power to the entire project easily, which effectively conserves battery capacity during idle periods.

Furthermore, this board simplifies your circuit layout by providing four large, circular connection pads. Specifically, the configuration includes two positive and two negative connection points. Therefore, developers can route multiple power lines or sew secure, redundant structural connections using standard conductive thread. As a result, the hardware streamlines the integration of power distribution within flexible substrates and wearable systems.

Applications

Engineers and e-textile creators primarily utilize this CR2032 Battery Mount Module as a primary energy source in e-textiles, wearable technology, and interactive apparel systems. For instance, the low-profile board acts as the central power node for miniature projects that require a lightweight, independent voltage supply sewn directly into fabrics or everyday garments. Moreover, the dual-terminal layout allows developers to build parallel power pathways to multiple LEDs, sensors, or microcontroller boards with ease.

Meanwhile, the mechanical slide switch makes the unit ideal for portable, self-contained interactive displays. External power modules often add unnecessary bulk or require complex disconnection procedures. However, this board eliminates that issue completely by providing local control over the power state. Ultimately, it offers a reliable, low-profile energy solution for mobile technology projects, theatrical costumes, and smart textile designs.

Maker Store Tips and Tricks

• Turn the slide switch to the “OFF” position before inserting or replacing the CR2032 battery to prevent sudden current spikes.

• Ensure your conductive thread stitches are tight around the connection pads to maintain consistent electrical continuity during project movement.

• Check that positive and negative thread traces never cross each other on the fabric to prevent direct shorts across the battery cell terminals.
