2 layer board of 3.15x1.93 inches (80.01x49.02 mm). Update: This revision is not fully functional, it can be made to work partially with minor modification but it is not suggested you order it. Rev v1.01 is planned to fix the issues preventing full functionality. Optically-isolated 4-channel automotive relay driver (ARD). Intended for use in lab environment, robust and flexible driver with 1A output possible per channel. Jumper to select between active-high and active-low inputs, jumper to select between DB9 or external power for input side. Reverse-protection on both logic and relay side power. LED across relay driver output indicates if relay is getting power. Test points for logic and relay power, as well as one per channel on logic side. Board fits Sick of Beige DP8049 form factor (but should be used with 10mm stand-offs between board and top panel). You can find this project on GitHub.
