GL.iNet has added the Comet X to its expanding Comet KVM range, with this model taking a more rack-focused approach than the earlier single-system units. Rather than being built around remote access to 1 machine, the Comet X is aimed at users who need to manage several nearby systems from a single KVM point, such as servers, workstations, test machines, or homelab hardware. It keeps the same general idea of browser and app-based remote control, but applies it to a 4-device setup with PoE support, local control options, and a chassis intended to fit more naturally into rack environments. At the time of writing, GL.iNet has shown the Comet X on its official pages, but has not confirmed a final price or general availability date
The Comet X is built around a 4-system KVM layout, with 4 HDMI inputs for video capture and 4 USB-C device ports for connecting the controlled host machines. It also includes 1 HDMI output, allowing a local monitor to be connected directly to the unit rather than relying only on remote access through a browser or app. This is an important distinction from many smaller remote KVM devices, as the Comet X is not only intended to sit between a user and a remote machine, but also to act as a local switching and troubleshooting point when working directly at the rack.
For peripheral support, the unit includes 7 USB 2.0 Type-A host ports, rated at 5 V/0.5 A per port, which can be used for external peripherals and local interaction. Networking is handled through a 1GbE RJ45 port with 802.3af/at PoE support, while a USB-C power input is also available as an optional 5 V/3 A PD-compatible power source. This gives the device some flexibility in how it is deployed, although the presence of PoE is clearly one of the more rack-oriented parts of the design, as it reduces the need for a separate power adapter in suitable network environments.
Internally, the Comet X uses a quad-core ARM Cortex processor, 1 GB of DDR3L memory, and 64 GB of eMMC storage. The storage is intended for firmware, system use, and image storage, including ISO files for OS deployment or recovery tasks. The unit runs Linux 6.1 and supports up to 4K@30FPS video handling. It also includes a 3.69-inch TFT touchscreen on the front, which is used to show device status information such as IP details, online or offline state, and active sessions. Physically, the unit measures 170 x 90 x 40 mm, weighs 560 g, and includes brackets for both 10-inch and 19-inch rack mounting.

The Comet X uses GL.iNet’s GLKVM software platform, which is shared across the company’s current Comet KVM range. This allows connected systems to be accessed through a web browser or through GL.iNet’s own applications for Windows, macOS, Android, and iOS. The core purpose is to provide direct keyboard, video, and mouse access to the attached machines, including scenarios where the target system has no working operating system, no remote desktop service, or needs BIOS-level access. For server maintenance, OS installation, remote troubleshooting, and recovery work, this is the main difference between a hardware KVM and normal remote access software.
The GLKVM software also includes a number of management features that are relevant to a multi-system KVM setup. These include video quality adjustment up to 4K@30FPS, remote file transfer, audio output, virtual keyboard support, Wake-on-LAN, 2-factor authentication, and support for accessories such as ATX boards and Fingerbot devices. The Comet X also supports remote access methods including GL.iNet’s own access service, as well as Tailscale, ZeroTier, and NetBird, depending on how the user wants to expose or restrict access. This makes it possible to keep the device limited to a local network, integrate it into an overlay VPN, or use a more direct remote access method where appropriate.
Where the Comet X is more unusual is in combining remote KVM access, local KVM operation, PoE power, rack mounting, and control of up to 4 systems in 1 device. The current small remote KVM market is mostly built around 1 host system per unit, while traditional multi-port KVM switches are often focused on local switching rather than browser or app-based remote management. The Comet X sits between those categories. It is not just a remote dongle for 1 computer, and it is not simply a local HDMI and USB switch. Its main role is to provide centralized access to several nearby systems while still allowing remote control, local fallback access, touchscreen status information, and ISO-based recovery from the same unit.
The main difference between the Comet X and the rest of GL.iNet’s Comet KVM range is the number of systems it is designed to manage. Models such as the standard Comet, Comet PoE, Comet Pro, Comet 5G, and Comet Q are built around access to a single connected machine, with the exact feature set changing depending on the model. Some focus on compact remote access, some add PoE, some add stronger standalone hardware, and the Comet 5G adds cellular connectivity for fallback access. The Comet X changes the role of the device by moving from a 1-system KVM into a centralized 4-system unit.
That makes the Comet X less of a direct replacement for the other Comet models and more of a separate branch in the same product family. A single-system Comet device may still make more sense for users who only need access to 1 PC, NAS, mini PC, or remote workstation, especially where size, cost, or cellular failover matters more than managing several systems in 1 place. The Comet X is better aligned with rack or bench environments where multiple machines are physically grouped together and need to be accessed from 1 management point. Its trade-off is that some features found elsewhere in the Comet line, such as built-in 5G failover, are not currently listed for this model.

GL.iNet has not yet confirmed the final price or launch date for the Comet X. The official product listing currently presents the device as an upcoming quad-port remote KVM, and GL.iNet’s wider product pages also label the Comet X as upcoming rather than available to purchase. GL.iNet has also publicly referenced beta tester recruitment for the Comet X, which suggests the device is still in a pre-release stage rather than a finished retail launch. Until GL.iNet confirms availability, pricing, regional distribution, and whether there will be any early-bird or campaign pricing, the Comet X should be treated as announced but not yet released.

Découvrez le NAS UGREEN DXP4800 Pro, un modèle avec un processeur Intel Core i3, 8 Go de RAM DDR5, double réseau (2.5 GbE et 10 GbE), et d'autres surprises.
Le post Test UGREEN DXP4800 Pro : un NAS avec 10 GbE, un Intel Core i3 et 8 Go de RAM a été publié sur IT-Connect.
L'expert en électronique connu sous le pseudo de Krauseler s'est mis en tête un truc que la plupart des ingénieurs auraient lâché au bout d'une semaine, à savoir fabriquer un vrai ordinateur qui tient dans le format exact d'une carte bancaire.
Et pas "à peu près la taille d'une carte" comme on dit tous pour un Raspberry Pi, non, non, la vraie norme ISO 7810, 85 mm sur 54, et surtout l'épaisseur, soit moins d'un millimètre. Sa Muxcard, il l'a sortie tout seul, chez lui, après des mois de bidouille, et le résultat est très impressionnant !
Alors déjà, "ordinateur", c'est lui-même qui le met entre guillemets. En réalité sous la fine couche de Kapton se cache un ESP32-C3, le microcontrôleur que tous les makers connaissent bien, avec du WiFi, du Bluetooth et une intégration Arduino aux petits oignons.
Donc pas de Windows ni de Linux là-dessus, ne rêvez pas, mais ça tourne sur du firmware maison flashé directement sur la puce, façon Arduino. C'est donc surtout ça qui fait râler les experts en expertise de Reddit, mais j'suis désolé, un machin qui calcule et exécute du code, ça reste un ordinateur. Et sinon, oui, avant que vous posiez la question, ça fait tourner DOOM... À 0,7 image par seconde, certes, mais ça tourne !
Mais le plus dingue, ce n'est pas d'avoir réussi à caser tous les composants car malgré ce qu'on pourrait croire, trouver des pièces assez fines, c'était la partie facile. Le vrai cauchemar, c'est la mécanique car à cette épaisseur, tout devient fragile. Le moindre pli, la moindre pression localisée, et paf, les soudures lâchent.
Krauseler a donc conçu des "îlots" rigides autour des puces et des zones de souplesse calculées ailleurs, pour que la carte plie sans jamais forcer sur les points sensibles.
Et la partie qui va parler aux bidouilleurs, c'est le circuit imprimé. Plutôt que d'attendre 3 semaines une commande de flexPCB chez un fabricant à l'autre bout du monde et de prier pour que ça marche, il a tout simplement gravé le sien à la maison.
Du ruban Kapton avec une feuille de cuivre laminée, une couche de photorésine, et une imprimante 3D détournée en machine de photolithographie pour insoler les pistes.... Ajoutez à cela le pochoir pour la pâte à souder, qu'il a fabriqué en empilant du film photorésine à usage unique, et voilà.
Si vous avez déjà tenté de fabriquer un circuit au marqueur , c'est le même principe, mais poussé à un niveau de dingue.
Le moment le plus douloureux, de ce que j'ai compris, ça a été le branchement de l'écran. Les connecteurs étaient trop épais, alors il a soudé chaque fil à la main en retenant sa respiration tellement c'est petit.
Maintenant, le point faible c'est la batterie. Un accu LiPo aussi fin, ça n'aime ni la chaleur, ni les chocs, ni qu'on s'assoie dessus avec le portefeuille dans la poche arrière. Une mini perforation et hop ça part en fumée, au sens propre.
Krauseler le reconnaît sans détour, et c'est sa plus grosse contrainte. Mais rassurez-vous, il bosse déjà sur des feuilles d'acier inox pour blinder l'accu contre la pression. Pas simple quand on sait que chaque solution crée un nouveau problème...
Bon, et qu'est-ce qu'on en fait au juste de cette Muxcard ?
Hé bien pour l'instant le proto affiche surtout des trucs sur son écran e-paper et joue les cartes de visite qui claquent. Mais pour moi, son potentiel qui fait rêver, ce serait d'imaginer qu'avec le NFC en lecture-écriture et l'ESP32, vous avez là de quoi bricoler un générateur de codes 2FA, un gestionnaire de mots de passe hors ligne, un portefeuille de QR codes pour vos billets de transport et autres, un portefeuille crypto, voire un petit outil de pentesting dans l'esprit du Flipper Zero .
Le tout dans un objet qui se glisse dans votre portefeuille sans que personne ne remarque la différence. En fait, le seul vrai frein, c'est qu'il faut savoir coder son propre firmware Arduino pour en tirer quoi que ce soit.
Maintenant, est-ce qu'on peut le refaire chez soi ?
Bien sûr, Krauseler a mis les schémas, le layout et un firmware d'exemple sur son GitHub mais attention quand même, c'est sous licence CC-BY-NC-SA, donc vous avez le droit de vous amuser à le reproduire mais pas de le vendre.
Maintenant, je pense que vous l'avez compris, reproduire ce truc relève de l'exploit. Il faut l'équipement de photolithographie, une soudure de précision de chirurgien, et surtout une batterie de moins d'un millimètre d'épaisseur que lui-même galère à sourcer. Et sur le coût total de tout ça, on n'a pas l'info ! Dommage, j'aurais bien aimé savoir combien ça coûte.
Bref, c'est moins un produit qu'une démonstration de force. Et c'est surtout une preuve de plus qu'un passionné seul peut encore repousser des limites que l'industrie jugerait pas assez rentable pour s'y coller...
