From the project

16 Channel Valve driver (designed for 12 volt Lee valves) using a Feather microcontroller

Feather compatible 16 channel valve driver.

This was designed for 12 volt Lee valves.

See errata for current minor electronic issues.

A simple 3d printed baseplate is included that supports the Lee valves:
