Computer requirements for VolTRAX V2b
VolTRAX V2b is driven by the VolTRAX software, which is responsible for the control of the device and consumable cartridge array.
VolTRAX V2b computer requirement is less demanding than a MinION™. If you are currently running a MinION Mk1B on Windows, or you plan to use a MinION Mk1B with VolTRAX, the computer requirements for your MinION Mk1B should be sufficient to operate the VolTRAX.
If you plan to purchase a system dedicated to VolTRAX V2b, the minimum requirements are:
Component Minimum specification Operating system Windows 10
macOS and Linux are in development.Memory/RAM 2 GB RAM CPU 64-bit dual core processor Storage/hard drive > 128 GB SSD User account privilege level Local administrator Ports USB TYPE C, 5 V, 3 A † Antivirus software Installation highly recommended Internet connection Appropriate firewall settings are required for downloading the VolTRAX software. † Only the USB TYPE C – Gen 3.1 (I or II) or higher – 5 V, 3 A can provide the full range of functionalities on VolTRAX V2b.

The VolTRAX status is displayed by LEDs
To ensure users can easily determine their VolTRAX status; a series of LEDs are included and described below.
Under-side LEDs:
The LEDs shown in the figure are indicators of the power supplied to the device.
- Red - This indicates that the USB Type-C cable is correctly inserted into the port on the device. This is for Development use only.
- Red - This LED signals that 900 mA are being supplied to the device; this is the least powerful type of USB-Type C or 3.1 Type I/II port. The device will operate basic protocols, but will not be able to perform thermal cycling required for PCR-based library preparations.
- Blue - This LED signals that 1.5 A are being supplied to the device; this is a commonly occurring power supply of USB-Type C ports. The device will operate basic protocols, but will not be able to perform thermal cycling required for PCR-based library preparations.
- Green - This LED signals 3 A are being supplied to the device; this is the requirement for the full capabilities of the VolTRAX V2B device.
- Blue - This LED signals power to the device.
- Blue - This LED signals power to the device.
- These are for use by Oxford Nanopore Technologies.
It is particularly important that LED 4 (green) is illuminated, if the user requires the thermal cycler to prepare their library. If the LED is not on, 3 A are not being supplied to the device.
To check that the laptop to be used with the VolTRAX has a port that supplies 3 A and that the power rating is set to 3 A, contact your IT Department.
Internally at Oxford Nanopore Technologies, we have used USB-power meters as a way of measuring the current provided by a USB port when a laptop is running off charge or plugged in. Users may wish to look into these in advance of their VolTRAX devices arriving.
