The biggest difference between the Otii Arc Pro and Otii Ace Pro hardware is in the power supply and sampling rate. Otii Arc Pro goes up to 5 V and has the sampling rate of 4ksps and goes Otii Ace Pro up to 25 V and has the sampling rate of 50 ksps.
Here is the detailed hardware comparison between Otii Arc Pro and Otii Ace Pro.
The package includes an Otii Ace Pro, a USB C cable, and a USB A to USB C adapter. Otii Ace Pro is used with feature-packed, multi-platform Otii software. Check the "What's included" page for further details.

If you choose to run with an external DC adapter, we recommend you to pick one from an established supplier. The adapter should be low noise, approved for IEC 60950-1 as a Limited Power Source. The output from the DC adapter can be in the range 7-20V, max 5A. Pick an adapter that is able to provide a little more than the output power you will need. Be aware that the voltage drop in most cables at 5A is not negligible.
Otii Ace voltage and power output range: 0-25V, 0-15W In most cases, the power supplied by your computer’s USB C ports will be sufficient since Otii Ace has PD implemented. However, not all computer’s USB C ports are created equal, today you mainly find 15W support, and if you experience problems you might need an external power supply, see the next section. Hint: By enabling ”meters” (Device => Meters) you can see the actual voltages. VBUS is the USB voltage. If this goes below 4.75V, you should switch to an external DC adapter. The input voltage from the external DC connector is also monitored (VDC) and this should not go below 7V.
Otii Ace voltage and power output range: 0-25V, 15-30W continuous power For this you should use an external DC adapter. There are many good ones available, and we recommend you pick a certified one of good quality with sufficient power rating and 7-20VDC, max 5A output. One example is TRH70A180-11E03 VI from Cincon Electronics Co. LTD, and available through Digikey.com but there are many more to pick from.
Otii Ace voltage output range: 0-25V, 30-50W peak power Otii Ace can support output power of more than 30W and less than 50W but not continuously. Otii Ace will be overheated if too much power is sourced and an overtemperature protection will shut down the power supply if needed.
