Digital I/O
Configure, read, write and monitor pins in real time.
No firmware coding required
Your Arduino,
Your Arduino,
reborn as a test bench.
SiccaLab is a Windows desktop app that turns Arduino boards into test and measurement instruments. Flash firmware once from inside the app, connect over USB, and drive every function from a purpose-built panel — no code, no toolchains, no guesswork.

Instruments
Eight instruments. One board.
Every panel is purpose-built for the job. Wire up a supported Arduino, pick a function, and start working — the interface does the heavy lifting.
Analog Input
Multi-channel voltage capture with configurable VREF and engineering-unit formulas.
PWM Output
Hardware PWM with duty-cycle control and live waveform preview.
Square Wave
Precision frequency generator with real-time waveform display.
DAQ
Binary data acquisition up to 100 Hz, one or two channels, live graph.
SPI
Master and Slave modes, multi-device support, full transaction log.
I2C
Master and Slave modes, bus scan, Write / Read / Write+Read with per-device logs.
UART
Hardware serial channels, ASCII/HEX send & receive, command history, CSV export.
All in one app
Switch between panels instantly — one download, one license, everything included.
Supported boards
Works with the Arduino you already have.
Start with the boards already on your bench. SiccaLab supports the most common Arduino form factors, with more on the roadmap.

Flagship feature
Build test sequences.
Build test sequences.
No code.
The Sequencer is a no-code test automation engine. Chain steps across every instrument, add named nested loops and variables, set pass/fail limit checks, debug with breakpoints, and export professional PDF and CSV reports — all without writing a line of code.
- ✓ 28 step types
- ✓ Expression engine
- ✓ Limit / check pass-fail
- ✓ PDF & CSV reports
Fully included in the 14-day trial.
How it works
From board to bench in three steps.
-
1
Connect over USB
Plug in your board and it's detected automatically — you're ready to go.
-
2
Flash firmware from inside the app
No Arduino IDE, no sketches. SiccaLab loads the firmware for you in a click.
-
3
Start measuring and testing
Run measurements, automate tests with the Sequencer, and watch results on live graphs — no code required.
Who it's for
Built for the bench, priced for everyone.
Affordable instrument control for the people who actually use it — from the classroom to the workshop.
