Everything Works When You Can See It

Development boards with built-in debugging, logic analysis, and power monitoring. Plug in one USB cable and see exactly what your firmware is doing — no external tools, no driver installs, no guesswork.

The Problem with Embedded Development

Every embedded developer has asked the same questions: "Is this pin doing anything?", "Did the chip actually program?", "Why does this work on one board but not another?" — Traditional boards leave you guessing. Zolex boards give you answers.

šŸ”

Built-In Logic Analyser

8-channel, 10 MHz capture. See SPI, I²C, and UART transactions in real time — right from the board. No external analyser needed.

šŸ›

Integrated Debug Probe

CMSIS-DAP over USB HID — works with OpenOCD, VS Code, and every major IDE. Zero drivers, zero Zadig, zero friction.

šŸ’”

LED Pin Dashboard

Bipolar LEDs show HIGH, LOW, and Hi-Z at a glance. See your GPIO state without touching an oscilloscope.

⚔

Power Monitoring

Correlate current draw with code execution. Find sleep bugs and optimise battery life — all through the same USB cable.

šŸ“‚

Drag-and-Drop Programming

Drop a .uf2, .hex, or .bin file onto the USB drive. The board programs itself — micro:bit style, on every OS.

šŸ”§

Smart Peripherals

On-board RTC & EEPROM give you a guaranteed-working I²C target. Your first peripheral project just works — watch every byte on the analyser.

How It Works

Every Zolex board carries a dedicated co-processor — the Warden — that watches your target MCU without interfering. One USB cable does everything.

1. Plug In

Connect a single USB-C cable. The board appears as a composite USB device — debug probe, logic analyser, serial terminal, and mass-storage drive — all using built-in OS drivers. No software to install.

šŸ”Œ

2. Write Code

Use your favourite IDE — Arduino, PlatformIO, STM32CubeIDE, VS Code, or even a plain text editor. The Warden supports standard CMSIS-DAP, so every toolchain works out of the box.

šŸ’»

3. See Everything

Launch the Zolex Workbench (portable .exe, runs from the board itself) to see live waveforms, GPIO state, power traces, and protocol decodes. Or use PulseView — we're SUMP-compatible.

Who Uses Zolex?

šŸŽ“

Students & Educators

Teach real debugging methodology — not just syntax. Students see every I²C byte, every power spike, every GPIO toggle. The HyperBoard carries the whole dev environment on the board itself.

Hobbyists & Makers

Arduino-compatible learning without the mystery. Built-in tools teach you how protocols actually work. No expensive external kit required — everything is on the board.

šŸ¢

Professional Engineers

Accelerate bring-up with known-good protocol slaves, integrated logic analysis, and power profiling. Platform-agnostic — works with STM32, ESP32, PY32, RP2040, and more.

šŸš€

Hardware Startups

Driverless USB means customer onboarding is plug-and-play. Integrate the Warden architecture into your own custom boards, or use ours as a reference design.

Zolex vs. Traditional Tools

One board replaces a debug probe, a logic analyser, a peripheral breakout, and a driver installation headache.
