Q21 Flasher Nano ET Dongle - OBD 2

The Nano ET is a professional, compact vehicle diagnostic interface. It combines full-featured workshop diagnostics with a compact design and is designed for permanent use directly on the OBD-II port. 

The Nano ET is the perfect counterpart to the Qntum21 Flasher.

Highly integrated, compact, and versatile – designed for the perfect interplay with the Qntum21 Flasher. Regardless of the area of application: The Nano ET provides the right hardware platform for maximum flexibility.

Versatile connection options via Wi-Fi, BLE, or USB-C offer maximum flexibility – whether on a PC, smartphone, or tablet. The software can be installed and used on multiple devices simultaneously.

As a bonus, the Nano ET includes the J2534 PassThru, ENET/DoIP, and ELM327 protocols – at no extra cost.

Discreet & permanently ready for use

The Nano ET can remain permanently in the vehicle – no constant plugging in and out. Three intelligent functions ensure safety, efficiency, and immediate operational readiness:

Intelligent sleep mode

The Nano ET automatically detects when the vehicle is not in use and switches to a deep sleep with minimal power consumption. When the vehicle is started, it wakes up immediately and is ready for operation without delay.

Protection against unauthorized access

The Nano ET communicates exclusively with devices that you have personally added to your trusted list. Unauthorized connection attempts are reliably blocked.

Adjustable communication range

The Bluetooth signal strength can be limited so that the Nano ET is only accessible within the vehicle interior – making access from the outside more difficult.

Important safety note – CAN-Bus / Ethernet pins

Warning: It is strictly prohibited to connect the Nano ET to vehicles where the CAN-Bus is located on pins 12–13 and 3–11 of the OBD-II connector. Since these pins are used for Ethernet on the Nano ET, a short circuit of the CAN-Bus may occur. Although this does not damage the vehicle electronics, it can lead to the logging of numerous error codes or the desynchronization of keys.
