Our Products

Three tools targeting the full embedded development lifecycle — hardware bring-up, protocol validation, and production test.

🔲

SuperBoard

A development board with a logic analyser, SWD debug probe, and LED pin dashboard built in. AT32F405 + RP2040. No extra bench gear needed for bring-up.

🔌

SWD MultiProbe

Seven independent SWD channels on one USB cable. Flash and test 7 ARM targets simultaneously. Designed for production test farms and hardware CI/CD pipelines.

Why Zolex

Each product solves a specific problem that off-the-shelf tools handle badly or not at all.

Bench-in-a-board

The SuperBoard puts a logic analyser, debug probe, and per-pin LED indicators on the same PCB as your development target. Stop juggling cables between a dev board, a J-Link, and a scope.

Integrated instrumentation on every single pin — visible truth instead of silent failure.

🔲

Protocol-level Zigbee testing

Testing Zigbee devices manually against the ZCL spec is tedious and doesn't scale. The Zigbee Test Tool scripts every read, write, and command — then validates responses automatically against expected values.

43 test scripts covering 93 ZCL clusters. Production-proven on commercial thermostats and sensors.

📡

Parallel SWD at scale

A J-Link farm for 7 targets costs over €8,000 in probes alone, plus a PoE switch and 7 separate USB connections to manage. The SWD MultiProbe replaces all of that with one unit on one USB-C cable.

Flash all 7 in parallel, run independent test scripts per channel, collect results centrally.
