FIND YOUR STARTING POINT

Three things engineers do with Otii.

Optimize device’s power consumption

Measure current draw at every device state, find the firmware that wastes the most energy, fix it.

  • Profile sleep + active modes
  • Sync power with UART debug
  • Compare before / after
Predict and validate
battery life

Estimate how long a battery will last in your device, compare batteries side-by-side, qualify the ones you’ll ship with.

  • Profile and emulate batteries
  • Compare runtimes across cells and device activities
  • Cycle test to qualify vendors
Automate power measurements in CI / scripts

Run regression tests on every firmware build, script multi-battery runs, integrate measurement into your benchmark setup.

  • JSON-based TCP API
  • Works with any language
  • Multi-instrument setups

HOW THE SUITE FITS TOGETHER

Hardware + software, one bench, one workflow.

LAYER 1 — INSTRUMENT + DESKTOP APP

Pick the instrument that matches your voltage range.

Both Otii instruments are 2-quadrant source measure units that profile power, supply your device, and measure currents from nanoamps to 5A.

LAYER 2 — SOFTWARE TOOLBOXES

Add capabilities to the same hardware.

Both toolboxes run on Arc Pro and Ace Pro. Buy them as monthly, yearly, or perpetual licenses.

Used by developers and teams in 4500+ companies in 70+ countries

I love my Otii Arc! Next to a scope, this is the best piece of test equipment an embedded hardware/software developer could want. Micropower measurements are a breeze and it replaces my power supply as my go to power source and analyzer. Small, precise, and portable this thing goes anywhere I need to go.

Peter Sterrantino, Sr. Principal Engineer at Stryker

“Can’t imagine firmware development now without using an Otii Arc, and Otii Automation Toolbox allowed us to automate our production power profiling during the final test.”

Mathew Key, CTO at Isansys

“Thanks to Otii, we have been able to reduce our Strips current consumption even further to reach more than 10 years battery life. Every developer should have Otii Arc.”

Mats Pettersson, CTO at Sensative

“Working with Qoitech and establishing this low-power mindset certainly enriches the LoRaWAN community.”

Wienke Giezeman, CEO at The Things Industries

“If you are looking into optimizing your IoT device for low-power design, reach Björn Rosqvist from Qoitech, I cannot express how much energy we saved with the Otii Arc.”

Tal Klinger, Hardware & System Engineering Team Lead at Trax Retail

“If you are doing anything, designing IoT devices, battery-driven devices, handheld devices or anything that uses power where you want to be conservative about the power get this device – it just works for you! Easy to use, out of the box and state of the art.”

Ole Valeur, Senior Global Application Engineer at Okdo

“My favourite developer tool is the Otii and the feature that I like the most is the UART log which is combined with power consumption display – it is wonderful to see AT commands running through the module and triggering the power peaks.”

Marcus Pihl, IoT Connectivity Specialist at Soracom

    Get your first power measurement in under 60 seconds.

    Order your Otii instrument, download the free Otii software, plug in. From there, add the toolboxes you need — or just stay on the free hardware tier indefinitely.
