I seem to have used up all the GPIO on my rpi and now I’m looking for an I2C expansion module with isolated inputs. Has anyone worked with the RaspiHats DI16ac? I like the design other than the MCU requirement (would be nice if they had just used something like the MCP23017) and the there is no IRQ line. Unfortunately they appear to be on vacation for a while and I’m impatient.
Any other boards out there that people know of?
Thanks,
Devan
