I2CDetect software utility built on a PCB business card.

This is currently a WIP. Plan is the DNP the JTAG connector and USB to TTL chip on the final build. Just adding them for development purposes. The USB-C connector will stay as I think there are too many LED's to make this battery powered.
I may add a button to trigger the i2cdetect function, that or the device will constantly poll i2c addresses.

Cute! I like the design with the reference to i2cdetect.
Might be nice to include a 3.3v pin in addition to sda/scl/gnd, so that you could test a breakout board with just this card + some jumper wires.
Might also be nice to include a Qwiic / Stemma-QT connector as well / instead of the 2.54mm header pins. They're low-profile and surface-mount, so you could probably have your PCB assembly house place them for you.
