Otii Arc Pro

Otii Arc Pro is an instrument that can precisely source voltage or current and simultaneously measure voltage and/or current. It computes power and energy, and syncs with software output, enabling engineers and developers to easily see what drains the energy and optimize the battery life of their devices under test. Created by and for hardware and software developers.<h3>Big features in small package</h3>The Otii Arc Pro is a small yet powerful measuring device that's 10.9 x 14.4 x 4.4cm (WxLxH) and weighs 450 grams. It provides a voltage of 0.5-5V and can measure current with a range of nA-5A and a resolution of 5nA, and it has a sample rate of up to 4ksps. You can connect it to your computer with a USB cable and use the Otii Pro software to analyze the measurements. The software works on Windows, Ubuntu, and macOS.<h3>Otii Arc Pro can be used for</h3><ul><li>Powering your devices under development</li><li>Energy profile microcontrollers, sensors and devices in real-time and over time</li><li>Optimizing sleep current and extending battery life</li><li>Estimating the battery life of your product</li><li>Designing power-efficient hardware, firmware and software through regression testing</li><li>Troubleshooting your hardware, firmware and software</li><li>Sync UART logs with power measurements to see what drains the energy</li></ul>Otii Arc Pro comes with featured-packed Otii Basic perpetual software and 1-year Otii Pro software. Additional software modules can be purchased to use it with scripting and to profile and simulate batteries and energy harvesting solutions like solar panels.
