Four DUTs. One box. Full control.

NablaBox lets remote developers and test engineers work on up to four devices under test (DUTs) as if they were sitting next to them – without exposing those devices to any outside network.

Each DUT slot provides switchable power, a serial console and a port on an isolated, switched network segment. The gateway itself connects outbound to your NetBird network, so the lab needs no inbound firewall rules at all.

Power control

Switch each DUT on and off from the browser, a script or your CI. Select 5 V, 12 V or 24 V per slot; a power cycle doubles as a hard reset.

Serial console

Open the DUT’s serial console directly in the web UI, or bridge it to any tool that expects a plain stdio console – LAVA included. One session per DUT at a time, so a human and an automated job never fight over the same line.

Isolated network

DUTs live on their own switched segment with DHCP and an NFS export for network boot. It is never bridged to the uplink unless you explicitly enable IP forwarding.

Test execution

Pick tbot test cases in the web UI, run them against a DUT and follow the output live. Every run is kept with its full log and result.

Preliminary specifications. Dimensions, weight and regulatory certification are pending final characterization.

Two enclosures

Choose the 1U 19″ rack-mount version for the lab or the desktop version for the bench. Both share the same electronics and front/rear panel layout.
