Key Chains

The documented key-chain display is the 1.54-inch class SE0154MNP36-FNG-A0, with 200 × 200 pixels and black, white, yellow, and red. This is a four-color display palette, independent of the enclosure color.

Before choosing

The supplier document uses 1.50-inch sizing while the firmware identifies the 1.54-inch class. Use the exact panel and finished-product dimensions to check fit; the size class is not a precise enclosure measurement.

The same size class is also included in Price Tags. Confirm the exact product, enclosure, and any included attachment in its storefront listing. No key ring, case color, battery arrangement, or accessory bundle is implied by this guide.

First update

1. Read the NFC getting-started guide.
2. Let the app identify the connected display through Metadata.
3. Prepare square artwork using the reported dimensions and four-color palette.
4. Keep the phone in place through preparation, transfer, and refresh until the app confirms completion.

Use text and image preparation for artwork, and troubleshooting if the update is interrupted.
