No. Wrong number of pins. This device has 40.

All PETs have a user port on the back that's an card edge. Original, static
RAM models have a card edge connector for memory expansion. Later models had
a pair of 40-pin pin connectors.

Given the apparent 0.1" spacing on this device and the number of pins, I'd
suspect that it's a TRS-80 device. I don't think it attaches to a Commodore
of any vintage.
