Qoitech Otii Arc Pro

Combine Qoitech's versatile power-optimising tool with their best-in-class software.

We use Qoitech's power monitoring solutions to test and calculate the run time for a Weather Station powered from AAA batteries.

Power your device directly from the DC input or battery connectors, then the Otii is ready to act as both a 0.5V - 5V DC power supply and high-resolution voltage and current monitoring system.

The Software will allow you to generate logs, graphs and stats based on the entire recording or small subsections even during the process!

You can compare how your software and hardware changes have affected your power consumption by comparing previous Otii project files to new recordings.

• All-in-one functionality: Otii hardware and Otii software integrates power supply, real-time monitoring, and detailed analysis in a single, compact, user-friendly product.
• Quick installation & easy to use: Download Otii 3 Desktop app, plug the Otii Arc Pro to your device under test (DUT) and start measuring energy data in less than a minute.
• Optimal power alternatives: Power up Otii Arc Pro based on your solution setup and power requirements via USB or an external DC adapter.
• Versatile connection: Power source your device under test using the Otii Arc Pro, which can deliver up to 5V at high voltage/current resolution. The DUT can be connected either through its DC input or battery connectors.
• Real-time measurements & analysis: Analyze and compare charts and measurements in real-time, covering currents, voltages, and power within the Otii 3 Desktop App – it allows scrolling, zooming, and selecting current consumption and debugging logs during measurement.
• Continuous serial synchronization: Measurements are continuously synchronized with debug logs from the device under test via UART.
• Responsive UI: Ensure smooth performance under heavy data measurements loads, supporting multiple streams and long recordings – optimized for high-definition displays to enhance user experience during analysis.
• Collaborative features: Share recordings and analyses with team members to get insights and feedback for further product releases on a recurring basis.
• Upgradeable software: Unlock a wider range of features and specialized functionalities, including battery profiling and automation tools.

Also recommended (basic use):

• IC Clips - these will fit into the Arc black and red outlets, which then connect to your device under test. You could use any standard banana plug style connectors though.
• If available, use a Yellow USB port or one with a lightning symbol to increase the power supply limit from 500mA to 1500mA (sometimes, these ports can go up to 3Amps).

Also recommended (advanced use):

• If you are powering devices beyond USB power constraints and would like to interface with the 14 port header, then read on.
• 27W Switch Mode Power Supply - set this variable supply to 7.5 Volts and your Arc will be able to power the device under test well beyond the USB limitation.
• SMD Clips and Through Hole Clips (Red / Black) - the 14 pin connector on the Arc has standard 2.54mm pitch, so you can use any female headers and crimps to make your leads to suit your project along with stranded wire for better flexibility.
• 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.
