New Temperature Sensors Are Here!!!

We received the latest revision of both the Brain and THP Probe PCBs. While the Brain update was purely about bugfixes, the Probes received a considerable facelift, including a new form factor, a new case, and a rack screw hole for mounting. Both the Openviro Axe Brain and the THP Probes are now in their final form factors, and one step closer to a final version. Read the full update.

Full Metal Enclosure!

Openviro has undergone a significant change this week with an upgrade to its enclosure. The initial 3D-printed IO shields, while excellent for prototyping, were not robust enough for long-term use in a rack-mounted environment.

The panels now offer a far better fit and finish, and have the added rigidity needed from a rackmount device. Keep reading for more details, a couple photographs, and a video! Read the full update.
