OTII-ARC-PRO, Qoitech Otii Arc Pro DC Power Analyzer, 5A Max, 5V Max

The Qoitech AB Otii Arc Pro 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 Arc Pro includes the Otii Arc measurement unit and the Otii software for Ubuntu, Windows & macOS. This product comes with a 1-year subscription to Otii Pro software. Connect Otii Arc Pro and power your device directly to the DC input or battery connectors. It will act as an up to 5V DC power supply and a high-resolution voltage and current measurement unit. Otii Pro software will give you real-time measurements and generate statistics based on the entire data set or small subsections even during the recording process.

Measurement sample rate of up to 4k samples per second
Quick to use – download the Otii app, connect Otii Arc Pro via USB to your computer, start the app and you can start your measurement project
Real-time analysis
scroll, zoom, and select parts of the current consumption
Configurable UI
Unlimited undo/redo
Fully responsive UI during heavy data measurement load (multiple streams, long recordings)
Full HDPI support

Also recommended (for simple 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 (for 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 Otii Arc Pro 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 Otii Arc Pro has a standard 2.54mm pitch, so you can use any female headers and crimps to make your leads to suit your project along with a 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 Pro 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.

What is Otii Arc Pro?

Otii Arc Pro is a small, portable power supply, a current and voltage measurement unit and a data-acquisition module. It can be powered by USB or by using an external DC adapter.
Otii Arc Pro is the ultimate developer tool for energy optimization, made for hardware, firmware and software developers.
Otii Arc Pro comes with 1-year Otii Pro software. The fallback software is Otii basic which is free but limited in features.
