Youmile 10PACK Coin Cell Battery Holder Lilypad CR2032 Battery Mount Module for Arduino
Product description
What it is
The Youmile 10PACK is a set of coin cell battery holders designed to work with Lilypad-style projects and CR2032 cells. These mounts include a small slide switch and four connection points (two positive, two negative) to provide a compact power solution for wearable electronics, textile-based computers and DIY kits that use conductive thread or soldering for connections.
What matters most
On paper, this accessory aims to simplify integrating coin cell power into soft electronics and Arduino-based wearables. The embedded on/off switch adds convenience, especially in projects where you want quick power control without removing the battery. The low-profile form factor makes it feasible to stitch into fabrics or mount on small boards, which is particularly useful for hobbyists experimenting with wearable tech and DIY robotics.
Key points
- Includes 10 packs of coin cell battery holders geared toward Lilypad-compatible layouts.
- Four connection points provide redundancy and easier wiring for simple circuits.
- Integrated on/off switch offers a straightforward power control option.
- Sized to suit Lilypad-style projects, product mentions a compact diameter and shallow height typical of wearable modules.
Practical use tips
For best results, plan your wiring so that the positive and negative pads align with your Lilypad or compatible Arduino-style board. If you’re sewing, conductive thread can be used as an alternative to solder, but ensure solid stitching to minimise resistance or loosening over time. Remember, these holders are generally suited to low-drain wearables, don’t expect them to drive high-current devices.
Who it’s for
- Makers building wearable electronics, soft robotics or textile-based computers.
- Hobbyists looking for an affordable, reusable power solution in a DIY kit format.
- Educators teaching beginner-level electronics with a focus on fabric-friendly projects.
What to consider before buying
- Suitability for your power needs: coin cells provide modest current, this solution is more appropriate for low-power wearables than for motors or high-drain components.
- Fabric integration: the small size helps with sewing projects, but ensure fabric tension and stitching won’t interfere with contacts.
- Replacement and availability: you’re buying in a bulk pack, check if 10 packs match your expected project volume.
How it compares to other approaches
If you’re choosing between a fabric-friendly coin cell holder and a larger, rigid battery mount, the Lilypad-friendly option wins on flexibility and integration into garments. For projects requiring higher current or longer runtime, a different power solution might be more appropriate.
FAQ (quick answers)
- Is this suitable for high-drain devices? Not ideal, better for low-power wearables.
- Can I sew these into fabric? Yes, the design is intended for textile projects with conductive thread or stitching.
- Do the packs come with CR2032 batteries included? The listing refers to holders in packs, not necessarily batteries, batteries would be separate.
Is it worth it?
Buying verdict: Worth considering if you’re building wearables or textile-based electronics and want a compact, sewable power solution with a simple on/off switch. If your project demands higher current, you may want to evaluate alternatives or use this as a secondary power option for light-duty components.
