or where i can buy it cheaper
For another i want to do this is so i can use the two servo outputs on a lor controller to control relaysIf you're just using them for on/off, couldn't you use some of the digital outputs of the Prop-1 to control a TTL relay board? How about one of these?
Also, a lot of solid state relays (SSR) will run on 3-32V, in which case you could run an SSR directly from a TTL output from the Prop-1.
