EDGE NETWORKING

Ethernet Switch Boards for Embedded System Integration

Bare-board Ethernet switches engineered for direct integration into UAVs, ground robots, underwater vehicles, and industrial platforms. Compact, rugged, and built for the environments where standard networking hardware fails.

SWITCHBLOX

Most embedded systems don't need a managed rack switch. They need a compact, reliable Ethernet backbone that fits on the board stack, survives the environment, and disappears into the architecture.

BotBlox Boards are unmanaged and lightly managed Ethernet switches in bare-board format. No enclosure. No unnecessary overhead. Just the switching fabric your system needs, at the size and weight your platform allows.

Every board in the family is designed for direct PCB integration or bracket mounting inside an electronics module. All variants are tested to MIL-STD-810H environmental standards — the same benchmark used to qualify military hardware for field deployment.

How Boards Fit Into Your Embedded Architecture

FORM FACTOR

Smallest Form Factor Possible

By shrinking the Ethernet circuitry down to just a bare board, we're able to achieve the smallest form factors possible while retaining full performance with the ethernet specification. For applications that are very SWaP sensitive, boards offer the best solution.

CONNECTIVITY

Cable Mate

BotBlox boards use headers such as Molex PicoBlade, PicoClasp and JST to mate directly with cables. This is far more space efficient than RJ-45 headers, while still being able to handle up to 10Gbps ethernet.

CONFIGURATION

Close-up of BotBlox PCB circuit traces with "Assembled in the USA from globally sourced components" — NDAA Section 889 compliant embedded networking hardware

NDAA Compliance

For applications that are supply chain sensitive, we offer NDAA compliant versions of nearly all our boards. Both our NDAA and non-NDAA compliant boards share the same design, allowing them to be interchanged within a system. Look for the blue colored boards if you need NDAA compliance.

FEATURES IN ACTION

Built for Environments Where Commercial Hardware Fails

Every board in the BotBlox family is tested to MIL-STD-810H — the U.S. Department of Defense standard for environmental qualification. Tests are conducted under operational conditions with continuous network load, not powered-off storage tests.

Temperature Range

−40°C to +85°C

Validated under high and low temperature, thermal shock, and rapid decompression at altitude equivalent to 30,000 ft.
