Keep serial-dependent equipment usable on current computers with the Brainboxes US-101. This 1-port USB to RS232 adapter is designed for teams that still rely on legacy devices but need a simple path to modern host systems. It creates a direct bridge between a USB connection and a single RS232 serial endpoint, helping preserve access to hardware that remains essential in labs, service benches, and field support workflows. The compact adapter format makes it easy to carry, deploy, and replace as needed. For technicians, that means fewer workarounds when connecting to controllers, diagnostic tools, or older peripherals that still speak RS232. For procurement teams, it offers a lower-risk alternative to replacing functioning serial equipment just to match newer computers. Brainboxes positions the US-101 as a practical connectivity tool for long-lived infrastructure. Its value comes from staying focused: one port, one job, dependable serial access. When the requirement is to keep legacy devices in service with minimal friction, this adapter delivers a clean, purpose-built connection point.
