Power supply, monitoring and analysis in one easy to use and feature-packed product, the Otii by Qoitech is the ultimate tool for any developer aiming to design highly energy efficient IoT projects.
Otii includes the Otii Arc measurement unit and the Otii software for Ubuntu, Windows & macOS, download here. Please note this product comes with a lifetime subscription to the Otii Software.
Connect Otii Arc and power your device directly to the DC input or battery connectors. It will act as both an up to 5V DC power supply and high-resolution voltage and current measurement unit.
Otii software will give you real time measurements and generate statistics based on the entire data set or small subsections even during the recording process. You can record and compare the changes in energy consumption due to changes in your software and hardware in one and same Otii project. Share the data with team mates and suppliers.
Today, based on statistics, tighter calibration limits and updates in the firmware, we can proudly announce an update to the technical specification.
The new accuracy for current measurements is ±(0.1% + 50nA) for currents below 19mA and ±(0.1% + 150uA) for higher currents. The new accuracy for voltage measurements is ±(0.1% + 1.5mV)
Previously we have stated ±(1% + 0.5uA) for current measurements and ±(1% + 10mV) for voltage measurements, so we are delighted with the improvements!

Also recommended (for advanced use):
USB Type A Female Breakout – this is a useful combination for USB device testing. The female connector can then be used with any Type A cable, which adapts to a Micro B or other popular USB variants. To enable Otii Arc to power 5V devices, in the projects settings menu, disable Current “Auto range”. This will unlock the main voltage from 4.55V to instead be 5V back on the “Supply” tab for your project setup.
