Product description

This is a 8-relay board with an ESP-12F.

Each relay has COM+NO+NC exposed. Product descriptions don't seem to specify maximum load.

The board can be powered either via 7-30VDC or via 5VDC (separate connectors).

I bought it from: https://s.click.aliexpress.com/e/_DnEOi2r (affiliation link so i can make others like this, no guarantee it will continue to exist).

GPIO Pinout

This board has headers for every GPIO pin on its ESP-12F.
