Wireflow and Pickering Interfaces have launched a joint venture called Testblox AB to provide modular automated test hardware. The company debuted with a line of over 30 miniature modules designed for streamlined test fixture integration.
Why it matters
The modular architecture is intended to reduce floor space requirements and the need for instrument racks in testing labs. By shortening signal paths through compact design, the system aims to improve overall signal integrity.
The modules are approximately the size of a playing card and feature individual ground plane isolation. Each unit supports connectivity via standard D-Sub connectors and is managed over USB using the Brygga software environment.
The players
Wireflow
A Swedish company specializing in multi-function I/O and power supply technology for industrial applications.
Pickering Interfaces
A United Kingdom-based manufacturer known for signal switching and simulation solutions for electronic test and verification.
Testblox AB
A newly established joint venture focused on producing modular hardware for automated test fixture systems.
The details
Designed and manufactured in Europe, these modules support Python, C#, and NI LabVIEW APIs. The system integrates Pickering Interfaces' switching technology and Wireflow's I/O and power supplies to minimize complex cabling.
Timeline
Testblox AB officially launched its product line on October 13, 2026.
The Tech Race
This venture represents a broader industry shift toward shrinking the footprint of test infrastructure. By competing with established PXI and rack-mount systems, Testblox AB seeks to capture demand for space-efficient, integrated modular architectures.
Engineers and lab technicians can expect reduced hardware setup times due to the simplified cabling enabled by these custom interface boards. The three-year warranty offers long-term maintenance assurance for facilities adopting the platform.
The takeaway
The use of standardized connectors and software APIs allows for faster integration into existing test workflows. Facilities looking to optimize floor space may find the playing-card-sized modules a viable alternative to traditional rack-mounted instrument stacks.
