Yo Dawg, I heard you like TeensyROM so I made a little TeensyROM to connect to your TeensyROM!

TappyROM is a complete NFC tag reader (tap) device in the form of a miniature TeensyROM cartridge--less than 5cm square! It can be used to easily program NFC "tags" which can then be used to launch a program by touching the tag to the device. It has been tested with the TeensyROM though is also likely usable with other devices/software.

Ten NFC cards are included which work with the TeensyROM's NFC loading capability. If you're shopping for more tags, NTAG215 cards/tokens/stickers are widely available and recommended.

You will need a USB A to C data cable (not included) for use with the TeensyROM. (Please ensure that the cable supports data transfer and not just charging.)

Color

This is normally stocked in translucent purple matching the case available as an option with new TeensyROM cartridge orders from Sensorium. If you would like TappyROM in a different color, please indicate in the Additional Instructions during checkout or use the Ask a Question or Contact Store button to inquire. For a selection of colors, please see the TeensyROM Cartridge Case listing.

Technical Information

The compact enclosure houses a PN532 type NFC reader module coupled with a CH340N USB interface, details which may be relevant if you're selecting NFC tags or want to interface with other devices.

If you have trouble writing a card, try holding it at an upward angle above or next to the device, or even behind/under TappyROM. (Reading tends to be extremely easy, but writing can be a bit particular about placement and interference.)

Additional

If you want to see how deep the rabbit hole goes, you can also use mini-TeensyROMs as NFC tags!
