Power supply and monitoring in one simple to use and feature-rich package, the Otii Arc by Qoitech is the ultimate tool for anyone wanting to design highly energy-efficient IoT projects.

Please note this product comes with a lifetime subscription to the Otii Standard software. For more advanced features (key features being scripting, battery simulation and importing logs), please get in touch with us.

You power your device directly to the DC input or battery connectors, then the Otii is ready to act as both an up to 5V DC power supply and high-resolution voltage and current monitoring.   

The Software will allow you to generate statistics based on the entire data set or small subsections even during the recording process. 

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

Features sense Pins, Can be used to compensate for voltage drop in cables or as extra votage sensors.

Features:

  • A sample rate of up to 4k samples per second. 
  • Measurement range of <100nA-5A, however, requires an external power supply if going beyond 500mA. 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.
  • Data+Power via USB. 2.1mm DC jack for external power.
  • Can record current, voltage and UART logs, displaying them as charts and interactive measurements
  • ADC has a differential measurement range of -81.9175 mV to 81.92 mV at 1 ohm.
  • Otii can measure subsystems while also monitoring the main supply. 
  • Two General Purpose Inputs
  • Two General Purpose Output
  • The Sense pins.
  • Synchronize debug logs
  • Monitor multiple units from the same computer. 
  • Crop, downsample & share
  • Product information sheet (PDF)

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 (RedBlack) - 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.
