Active prototype developmentMany-to-many input concentrator
Ursa Router
A hot-swappable switchboard for assistive input: plug in switches or pair a device like Murmur, then route any of them to any target device without physically reconnecting anything.

What it does
Router takes input from multiple assistive devices at once — mechanical switches (sip-and-puff, pillow switches) plugged into 3.5mm jacks, or smart BLE devices like Murmur — and routes any of them to any target device: computer, phone, tablet, or TV.
One press of the routing button re-targets a switch from one device to another. No unplugging, no re-pairing, no digging through settings on the target device itself.
How it works
- Two 3.5mm jacks accept standard assistive switches directly — the switches people already own keep working, with nothing new to learn.
- A BLE radio pairs with smart Ursa devices, so a single Router can mix wired switches and wireless devices in the same routing table.
- Status LEDs report connection, battery, and current routing target at a glance, without needing to open an app to check.
- A USB-C port provides wired fallback to a target device when BLE isn't available or reliability matters more than convenience.
Router pairs directly with Murmur and routes every signal into Relay.
