JetKVM Mini Cuts IP KVM Cost to $39 With ESP32-P4X

A $39 IP KVM Built on a Microcontroller Instead of Linux

The JetKVM team has announced the JetKVM Mini, and the interesting part is not the price so much as how they got there. The original JetKVM ran Linux on a Rockchip SoC, which meant paying for DRAM and eMMC. The Mini runs FreeRTOS on an Espressif ESP32-P4X instead, and dropping the Linux tax takes an IP KVM down to $39.

• Processor: ESP32-P4X dual-core RISC-V at 400 MHz, 768 KB L2, 32 MB PSRAM, 16 MB flash
• Video in: HDMI capture at 720p60 or 1080p30, streamed as H.264 over WebRTC
• Two models: Mini with 100 Mbps Ethernet at $39, Mini W with WiFi 6, Bluetooth and 802.15.4 via an ESP32-C5 module at $42
• Size and shipping: 42 x 42 x 23 mm aluminium enclosure, with units due October 26, 2026

What Does an IP KVM Actually Do for a Homelab?

For anyone who has not needed one: a KVM over IP sits between a computer and the network and gives you keyboard, video and mouse access at the hardware level. Not remote desktop — hardware level. That means you can watch a machine POST, get into BIOS, pick a boot device, and recover a box that has no working operating system at all, from anywhere. In a homelab that is the difference between a five-minute fix and a trip to wherever the server lives.

The catch has always been price. Enterprise KVM-over-IP appliances ran into the hundreds of dollars, and the open-source wave that followed — including the ESP-KVM ESP32-P4 project and Radxa's LinkR USB-stick KVM — has been steadily grinding that down. The JetKVM Mini is the same trend arriving as a finished retail product.

Why Does Dropping Linux Save So Much Money?

This is the part worth dwelling on, because it is a design lesson that applies well beyond KVMs. A Linux-capable single board computer needs external DRAM and some form of mass storage, and those two components carry real bill-of-materials cost plus the board area and routing complexity that go with them. Moving to a microcontroller with 32 MB of on-package PSRAM and 16 MB of flash means the RAM and the storage are simply part of the chip.

The trade is that you lose a general-purpose OS. On FreeRTOS you are writing against a real-time kernel, and the H.264 encode, the WebRTC transport, the USB HID emulation and the virtual media all have to fit in a fixed memory budget with no swap and no package manager. That the ESP32-P4X can carry that workload at all is a sign of how far the high-end RISC-V microcontroller class has come — the same silicon generation that recently showed up as a Tomb Raider port running on about one watt.

Specs Worth Reading Closely Before You Buy

A few details deserve attention. HDMI capture tops out at 720p60 or 1080p30, which is fine for BIOS screens and console work but is not a remote workstation. The wired Mini is 100 Mbps Ethernet rather than gigabit — again, adequate for the job, since an H.264 console stream is not bandwidth-hungry, but worth knowing. The 240x240 IPS display on the front is a status readout, not a working screen.

The optional JetKVM OS Services push further: with the host agent installed on Windows, macOS or Linux, the Mini can do 4K capture, clipboard sharing and file transfer. That is a nice tier to have, though it is worth noting it only works once the host is healthy enough to run software — which is precisely the situation where you did not need the KVM. The bare-metal path is the one that matters, and it does not depend on the agent.

At $39 single or $33 each in a three-pack, the calculus changes for anyone running more than one machine. Putting a dedicated KVM on every node stops being a splurge and starts being cheaper than one wasted afternoon. Shipping is slated for October 26, 2026, so this is an announcement rather than something you can plug in this week.
