## Summary description

LilyPad RTC adapter module designed to hold a CR2032 coin cell and provide real-time clock functionality. Compatible with wearable and textile electronics that use LilyPad form factor; allows timekeeping for projects such as data logging, timers, alarms, and scheduling. Compact and easy to integrate into circuits where a small onboard battery-backed clock is needed.

## Long description

The LilyPad RTC adapter module for a CR2032 battery provides a compact, battery-backed real-time clock solution for wearable and textile electronics built to the LilyPad form factor. The module holds a single CR2032 coin cell to maintain time when the main power is disconnected, enabling accurate timekeeping for small projects. Designed for simple integration, it connects to standard LilyPad-compatible boards and components to add clock, timer, alarm, or scheduling capabilities with minimal footprint.
Advantages
This adapter module offers persistent timekeeping through a CR2032 cell, preserving clock settings during power loss and supporting long-term battery operation in a lightweight package. Its LilyPad-compatible layout simplifies attachment to textile circuits and sewable electronics using standard pads and spacing. The compact dimensions and low power requirement make it suitable for projects where space and energy are limited, while straightforward electrical connections reduce integration time.
Suitable for
Wearable electronics requiring timekeeping functions
Textile and sewable projects that need timers or alarms
Data logging setups that record timestamps
Portable or battery-powered prototypes with scheduling needs
Key specifications
Battery type: CR2032 coin cell (user-supplied)
Form factor: LilyPad-compatible layout for sewable electronics
Function: Real-time clock with battery backup
Mounting: Sewable pads and standard LilyPad connection spacing
Operating condition: Designed for low-power clock retention
How to use
Install a CR2032 battery into the holder, ensuring correct polarity. Sew or connect the module to your LilyPad-compatible circuit using the provided pads, aligning connections for power, ground and clock signal lines according to your clock chip wiring or microcontroller interface. After connection, set the time using your microcontroller or software interface compatible with the RTC chip on the module; once set, the battery will keep time while the main power is removed. Replace the coin cell when timekeeping becomes unreliable or when battery voltage drops below the required threshold.
Usage recommendations
For reliable long-term operation, use a fresh high-quality CR2032 cell and avoid prolonged exposure to extreme temperatures. Verify polarity during installation and follow standard sewable electronics practices to prevent short circuits in textile projects. Periodically check the time and replace the battery as part of regular maintenance for devices that require accurate timestamps.
