Universal USB I/O Interface
Abrantix Pulse
Compact, powerful USB-to-I/O interface for modern vending machines, unattended terminals, and payment systems. One device. Every vending standard.
Designed For
Real-World Vending Environments
Galvanic Isolation
Full electrical isolation between USB host and field I/O protects your system from voltage spikes, ground loops, and the electrical noise common in industrial vending installations.
Configurable I/O
Adaptable input and output pull-ups let you match different machine generations and regional standards — without hardware changes or additional components.
Wide Voltage Support
Mixed-voltage environments are the norm in vending. Pulse Hardware handles internal pull-ups at 5 V or 12 V and external voltages up to 24 V, covering legacy and modern systems alike.
USB-Powered Operation
Powered directly from the USB-C host at 5 V. Simple deployment, simple maintenance — no external power rails, no additional wiring, no complexity.
Specification
Key Features
Pulse Hardware was built to solve a real field problem.
Bridging modern USB-based hosts with the legacy and industrial interfaces that vending and payment systems still rely on — cleanly, reliably, and without compromise. It enumerates as a standard CDC serial device. No drivers, no surprises.

In-Field Updates
Supports unattended firmware updates — no bench access required. Maintain and upgrade devices in the field.
Applications
Perfect For
The same hardware adapts across your entire project portfolio — from prototyping to production, from field service to certification labs. Fewer SKUs, faster development cycles.
Vending Machine Controllers
Directly interface with vending machine I/O using Pulse, BDTA, or BACTA protocols. Ideal for controller replacements and upgrades.
Cashless Payment Integration
Connect modern cashless payment modules to legacy vending infrastructure without custom PCB development.
Retrofit & Modernization
Upgrade existing vending hardware to current standards while preserving mechanical and I/O compatibility.
Test Benches & Lab Automation
Automate I/O stimulus and measurement in test environments. Controllable from any USB host running test automation software.
Development & Certification
Prototype new controller concepts and validate against vending interface standards before committing to production hardware.
Field Diagnostics & Service
Use as a portable field tool to diagnose, test, and verify vending machine I/O from a laptop or Android terminal.
Developer-Friendly Simple Integration
Pulse Hardware enumerates as a standard serial device via USB-CDC — no custom drivers, no vendor SDKs required. Control it from any host environment that can open a serial port.
Its flexible I/O configuration means the same hardware can be reused across multiple projects, reducing BOM complexity and speeding up development cycles.
