Product Details


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. 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.


•Records currents, voltages and UART logs and displays them in real time as charts and interactive measurements and comparisons
•Recordings synchronized with UART debug logs
•Enables long continuous recordings, recording time limited only by computer storage
•Sample rate of up to 4k samples per second.
•Measurement range of <100nA-5A. Requires an external power supply if going beyond USB capabilities. Note: If using a Yellow USB port or with a lightning symbol, often they can power up to 1500+mA without the need for an external power supply. Check your USB port power limits for more info.
