Continuing the saga of designing a "tries to meet all requirements" current loop converter, I've decided to redo it as a modular design with separate modules for: - Loop supply - Receive converter - Transmit converter This will make the board smaller, plus you won't have to populate the modules you don't need. They'll also be available for inclusion in other projects. The edge connector spacing is intended to mate with Digi-Klips or have 0.1" pin headers soldered on. It's a single-inline connector, so it's breadboard friendly too. Here's some pictures of the 24V isolated loop supply module: http://imgur.com/a/U9RMK I'll probably end up using that module in projects not related to the current loop project, too! Thanks, Jonathan
