Acroname MTM-IO-SERIAL
Software-Controlled USB Hub, GPIO & Serial Communications for Automated Test
The Acroname MTM-IO-Serial combines programmable USB switching, adjustable-voltage GPIO, and serial UART interfaces in one rugged module. Test devices across multiple voltage rails, communicate over USB or serial, and control it all through the BrainStem API—ideal for automated functional test systems that need flexible digital I/O and communications.

Why Choose the MTM-IO-Serial?
Multi-Voltage Device Testing
Test devices running at different logic levels without hardware changes. Software-adjustable voltage rails (1.65V–5.0V) let you switch between 1.8V, 3.3V, and 5V devices on the fly.
Programmable USB Control
Isolate or enable USB ports under software control. Perfect for USB device enumeration testing, power cycling, and fault injection scenarios.
Flexible Serial Communication
Four UART ports with adjustable voltage levels handle serial communication with a wide range of embedded devices. Hi-Z disable prevents bus conflicts during test sequences.
Production-Ready Durability
Part of Acroname's Manufacturing Test Module (MTM) series, ruggedized for CM and OEM environments worldwide. Designed for 0°C to 70°C operation without external cooling.
Seamless MTM Integration
Connects to the BrainStem I2C network alongside other MTM modules. Control via host PC using the BrainStem API (C++, Python) or run standalone embedded programs.
Ideal Applications
- USB device enumeration and power cycling tests
- Multi-voltage embedded device testing
