JetKVM Mini: a $39 KVM the size of a matchbox
JetKVM rebuilt its remote-control box around a single microcontroller, and the price fell to $33 a unit in a three-pack.
In brief
JetKVM rebuilt its remote-control box around a single microcontroller, and the price fell to $33 a unit in a three-pack. Dropping Linux for an ESP32-P4X with a hardware H.264 encoder cut the cost enough to put a KVM on every machine, not just the important ones. Originally reported by JetKVM.
A matchbox-sized KVM
JetKVM Mini is 42 x 42 x 23 mm of aluminium and starts at $39, or $33 each in packs of three. The wireless Mini W is $42, or $36 in a three-pack.
Same JetKVM, less of it
It captures video at 1080p natively, drives keyboard and mouse over USB, and runs the same web interface, cloud, and updates as the full-size unit. OS Services push capture to 4K.
“It does what a JetKVM does”
Pick a port or a radio
The Mini has an RJ45: plug in Ethernet, video, and USB, then read the IP off the display. The Mini W swaps the jack for 2.4 and 5 GHz Wi-Fi, set up over Bluetooth from your phone.
“It is for machines a cable does not reach”
Not a stripped-down version
JetKVM started over rather than cutting features. The goal was a unit cheap enough to leave on every machine, re-engineered around the four things a KVM must do well.
“The Mini isn't a stripped-down JetKVM.”
One chip does everything
An ESP32-P4X handles capture, H.264 encoding, USB, and firmware with no separate DRAM or eMMC. Video streams to the browser over WebRTC at 1080p30 or 720p60.
Two USB ports, two jobs
One port runs at 480 Mbps to the target machine, presenting keyboard, mouse, and virtual media from a TF card while drawing power from it. The other takes extensions or backup power.
Open firmware, familiar software
The rewritten ESP32-P4X firmware is open source from day one and speaks the same protocols, so virtual media, Wake-on-LAN, Home Assistant, OIDC, and rollback updates all carry over.
“over-the-air updates with automatic rollback”
Lock it down, then buy it
A digest of JetKVM's signing key ships in the chip's eFuse, so one setting permanently restricts the Mini to signed firmware. Both models reach resellers on October 26, 2026.
“Secure boot, when you want it.”
The key point
Dropping Linux for an ESP32-P4X with a hardware H.264 encoder cut the cost enough to put a KVM on every machine, not just the important ones.
