JetKVM Mini: a matchbox-sized KVM with 1080p capture and open-source firmware from $39

JetKVM has introduced JetKVM Mini, a matchbox-sized KVM that keeps the capabilities of the original device in a 42 x 42 x 23 mm aluminium case. A press release dated 11 September 2026 announced two models: JetKVM Mini with Ethernet for $39 and the wireless JetKVM Mini W for $42. In packs of three they drop to $33 and $36 per unit. Both go on sale on 26 October 2026 through authorised resellers, with native 1080p video capture, keyboard and mouse over USB, and the same web interface, cloud and updates as the larger JetKVM.

Ethernet or Wi-Fi

The base Mini has an RJ45 port: connect Ethernet, video and the USB cable to the target computer, read the IP address off the display and open it in a browser. Setup mirrors every other JetKVM. The Mini W drops the RJ45 for a 2.4 and 5 GHz radio, aimed at machines a cable cannot reach, such as a PC in another room, a box under the TV or a rack with no free switch ports. Video and USB are the only cables it needs, and setup happens over Bluetooth from a browser on a phone or laptop: pick a network, enter the password, and the device joins it.

Hardware: an ESP32-P4X and two USB ports

The Mini runs on an ESP32-P4X, a microcontroller with a hardware H.264 encoder. Video is captured at 1080p and 30 fps or 720p at 60 fps, encoded on the chip and streamed over WebRTC to the browser; the Mini W adds an ESP32-C5 for wireless, covering 802.11a/b/g/n/ac/ax on 2.4 and 5 GHz, Bluetooth LE for setup and 802.15.4 for Zigbee and Thread. One USB port connects to the managed computer at USB 2.0 High Speed (480 Mbps), presenting keyboard, mouse and virtual media while drawing power from that machine; virtual media runs from a TF card in the side slot. The second port runs at USB 2.0 Full Speed (12 Mbps) and can serve as a backup or secondary power input. It hosts the company's extensions, which are being reworked to standard USB, and with an external power supply it can act as a USB host for other devices.

Software, secure boot and availability

The firmware was rewritten for the ESP32-P4X and is open source from day one. It speaks the same protocols as the original, so the web interface and cloud carry over unchanged: keyboard and mouse control, text paste, keyboard layouts, virtual media from an ISO on the TF card, JetKVM Cloud for access from outside the network, Wake-on-LAN, MQTT and Home Assistant, OIDC login, plus over-the-air updates with automatic rollback. JetKVM OS Services, whose companion service for the monitored machine arrives in the coming weeks, will support the Mini from day one and adds up to 4K capture, a shared clipboard, a guest terminal and file transfer. On secure boot, a digest of JetKVM's public signing key is preinstalled in the chip's eFuse, so owners can permanently lock the device to JetKVM-signed firmware with a single setting in the web interface.
