Is a 5 V trinket capable of sourcing enough current to drive this SSR?

Can't tell without seeing a datasheet. The product page says it can accept 3v to 28v input and handle 40A of controlled AC, but doesn't say how much input current it needs.

Hopefully a spec sheet is included with it when it arrives

According to the sheet, it takes input signals of 3v-32v DC with an ON threshold of 2.4v. It requires 7.5mA with a 12v input. Most likely less at 5v..

If I recall the trinket can handle 150 mA so I should be fine. Correct?

Per-pin, you should try to keep it under 20mA. But you are probably still OK

Re: Can 5v trinket drive SSR?
Just wanted to add that I've driven 4 of those SSRs directly from a Mega256 board, so all is good.
In a later rev of the project, I swapped out the mega board with an esp8266, which required me to use transistors to pump up the current driving the SSRs.
