A ProMicro-compatible board built for production-ready installs and fast prototyping—no soldering required. Every I/O and USB pin is exposed on screw terminals, so you can wire up sensors, switches, and even the USB data lines in seconds. The board ships with a rugged, panel-mountable USB-C cable (135mm, USB 2.0, 4-wire) and supports metal hardware for secure, grounded mounting.

Why this board?

Typical ProMicro boards force you to solder headers and mount the USB port flush with your enclosure, which can lead to awkward fits or broken connectors. With this design, all pins—including USB—are available on screw terminals. The included USB-C connector can be mounted on your product enclosure.
