It presents as a USB composite device: HID keyboard/mouse plus a CDC-ECM network bridge, giving a private USB Ethernet link (target at 192.168.11.2, phone at 192.168.11.1) with no drivers needed on most systems. Because HID works without an OS, it reaches BIOS screens and boot menus. Two variants exist: Mini (USB-C, BLE-only, $42) and Plus (USB-A, adds wired USB up to 10 Mbps, $42), both cheaper-competing against InputStick and DexoPad. The KeyCmd phone app (Android APK now, iOS coming) adds features like Compose & Send, macros, presentation mode, and an experimental AI Agent Mode that plans terminal commands from an LLM API key or a local on-device model. Caveats: BLE encryption isn't enabled yet, CE/UKCA certification is pending, units will ship in a 3D-printed enclosure, and Windows support needs RNDIS still in development. The campaign has raised $9,618 of a $15,000 goal, closing October 1, 2026, with shipping estimated February 14, 2027. ## Full article daily.dev links to this article rather than hosting it.

Openterface KeyMod is a tiny USB dongle that plugs into a target machine and presents itself as both a USB HID keyboard/mouse and a USB network bridge using CDC-ECM. This creates a private USB Ethernet link where the target gets a fixed IP of 192.168.11.2 and the phone gets 192.168.11.1, enabling SSH over BLE or USB with no drivers or network setup needed on macOS and Linux targets. _Developers managing headless servers can follow hardware releases like this on daily.dev as they ship._ ### Does the Openterface KeyMod support Windows targets for its network bridge feature? Not yet. The network bridge works with macOS and Linux targets today because it uses the CDC-ECM USB standard, but Windows requires RNDIS instead, which is still in development and not yet supported. _Anyone comparing cross-platform hardware tools can track compatibility updates like this on daily.dev._ ### Is Bluetooth encryption enabled on the Openterface KeyMod dongle? No, BLE encryption is not turned on yet. The security design is finalized using Bluetooth LE Secure Connections with AES-128 and ECDH P-256, but current beta and engineering kits ship without it enabled; the switch-on is planned via a firmware update before the product ships, and the wired USB link on the Plus variant bypasses BLE entirely if wireless exposure is a concern. _Security-conscious builders evaluating new hardware can watch for firmware update news on daily.dev._ ## Similar posts on daily.dev - [Openterface KeyMod turns your smartphone into a USB keyboard, mouse, gamepad, or SSH client \(Crowdfunding\)](https://daily.dev/posts/openterface-keymod-turns-your-smartphone-into-a-usb-keyboard-mouse-gamepad-or-ssh-client-crowdfu-lgzfv0lpp) · CNX Software · 0 upvotes · 0 comments - [Comet Q USB-C KVM device is made for smartphones, tablets, and laptops \(Crowdfunding\)](https://daily.dev/posts/comet-q-usb-c-kvm-device-is-made-for-smartphones-tablets-and-laptops-crowdfunding--71a8gtwye) · CNX Software · 0 upvotes · 0 comments - [Your Laptop Keyboard, On Another Device](https://daily.dev/posts/your-laptop-keyboard-on-another-device-iks8sodls) · Hackaday · 0 upvotes · 0 comments --- Tags: [#ssh](https://daily.dev/tags/ssh), [#raspberry-pi](https://daily.dev/tags/raspberry-pi) [View this post on daily.dev](https://daily.dev/posts/this-tiny-usb-device-turns-your-phone-into-a-keyboard-mouse-and-ssh-terminal-gcmljxb1j)
