attiny1616 (TheCacophonyProject)FirmwareConfidence: Medium

Firmware drives a new I2C repeater enable pin, and the PR notes "PA3 isn't connected on older PCBs, so driving it does nothing there." It was flashed and tested on a new-PCB camera, with i2cdetect results, and lists what was only run with stubs. When one team owns firmware and board revs, the handoff holds up.
