Hacking Digital Calipers
How is the board powered? By the same cell as is already in the calipers? What is that thin connector called that runs from the SAM32 to the calipers?

The board is probably powered by USB, because if the whole point is to emulate a keyboard and type in the numbers, then you're going to have USB anyways.

Not necessarily, ESP32 has WiFi and Bluetooth so you could emulate a Bluetooth keyboard or so something entirely different using WiFi.
But yes, I suspect USB like you suggest.

Uh, the actual article says it's USB, and talks about HID implementation and so on.
No need to second-guess anything.
