Unveiling Qoitech's Otii Range of Power Monitors: A Game-Changer for IoT Devices

In the world of IoT devices, understanding power consumption is crucial. At Hardware Pioneers Max 2023, we had the pleasure of meeting Werner from Qoitech, who introduced us to their Otii range of power monitors.

The Otii range, including the Otii Arc Pro and the new Otii Ace Pro, are programmable power supplies that can both sink and source current. This unique feature allows them to discharge batteries, creating a battery discharge curve that can be used to emulate the battery in an application. This is particularly useful for characterizing the battery you want to use in your products.

But the Otii range doesn't stop there. It also offers the capability of synchronizing current consumption with UART outputs from your IoT device. This feature allows you to see the correlation between your device's output and its current consumption, making it easier to identify and address power spikes.


The Otii Arc Pro and Otii Ace Pro differ slightly in their capabilities. The Otii Arc, which has been available since 2017, offers a range of 0.5 to 5 V and can sink up to -2.5 A. The Otii Ace Pro, released at the end of 2022, is a more advanced model with a sample rate of up to 50 ksps, with a range of 0 to 25 V, -5 to 5 A and a completely floating output. Both products have significant wide range current measurements and measure accurrately down to nAs.


The Otii range of software is another key selling point. It allows you to interact with the power monitors and script using Python or any other language. This makes the Otii range not only a powerful tool for hardware engineers but also a versatile tool for software developers.
