- There's a single (unused in grip) pin that shows some digital communication on camera start, photo shots and sometimes random "messages" on idle. Signal is active-low 3.3v, around 50kHz, but no luck trying to treat is as 57600 serial communication.

Here's my attempt at manually identifying the message format and timings. It appears to be UART, bit time about 18.5-19 microseconds, so about 52000-54000 baud. Couldn't identify any plain text in these short fragments, though.
