Reference Build
This page documents the maintainer's actual fielded build: the components, vendor links, photos, and basic spec sheet for each piece. Kinboard runs on any HDMI display + any small PC, but if you want a known-good combination this is one.
If you only want the software setup on the same hardware, jump to Kiosk-Windows-11-Mele-4C. This page is the hardware side.
The kiosk in its current home: portrait orientation, oak frame, single power cable to a Schuko outlet below. The room thermostat to the left isn't part of the build. The small black protrusion above the frame is the LD2410 presence sensor in a printed enclosure.
| Component | Choice | Approx. cost (Q1 2026) |
|---|---|---|
| Touchscreen panel | Novomatic 27" open-frame, 1920×1200, capacitive multi-touch USB | €240 (used) |
| Mini PC | Mele Quieter 4C (16 GB / 256 GB eMMC, Intel N100/N150 fanless) | $470 / ~€440 |
| Presence sensor | HLK-LD2410 (or B/C variant) on USB-UART (FTDI/CH340) | €10–15 |
| Wooden frame | Custom oak, hand-built to fit the panel | DIY |
| Cables + PSU | HDMI or DisplayPort cable, USB-A→B (touch), 12V DC PSU (panel), 12V DC PSU (Mele) | ~€20 |
| Mounting hardware | Wall mount of your choice | ~€10 |
| Total | ~€720–€750 |
The Mele is the most expensive piece by a wide margin and the touchscreen is the second. Everything else rounds out the build. You can use also a RPI 4+ but i wasnt satified with the on screen keyboard various linux dustrubutions deliver.
Sourced from comCurrent in Nürnberg via eBay (used / professionally refurbished). Listing format: "27" 68,6cm TFT 16:9 FULL HD M270HVN02.0 MONITOR TOUCHSCREEN DVI DISPLAYPORT VGA".
The model designation M270HVN02.0 is the underlying AUO panel; Novomatic packages the panel + touch overlay + driver board into an open-frame industrial assembly that's typically used in casino displays, POS terminals, or info kiosks. Used units come up regularly because the gambling-machine refresh cycle dumps them onto the secondary market.
| Diagonal | 27" / 68.58 cm |
| Resolution | 1920×1200 (16:10 — the seller's listing says 16:9 but the panel is 16:10) |
| Panel type | TFT LCD, AUO M270HVN02.0 |
| Touch technology | Capacitive multi-touch, glass surface |
| Touch interface | USB (HID, plug-and-play on Windows 7/10/11; works on Linux without drivers) |
| Video inputs | DisplayPort, DVI, VGA |
| Power | 12V DC, ~54 W draw, barrel jack, PSU included |
| Dimensions | 620 × 370 × 43 mm (W × H × D) |
| Construction | Open frame, metal chassis, no integrated stand |
| Bezel | Effectively none — the panel + touch glass go right to the edges |
- Open-frame is exactly what you want for a custom-enclosure build like this one. No plastic bezel housing to dispose of, no manufacturer logo, no stand to remove. Just the panel + a metal back chassis with the driver board.
- DisplayPort is the cleaner choice over HDMI for a long-running kiosk — better with monitor sleep / wake transitions, no HDCP weirdness.
- Capacitive glass-surface multi-touch matches modern phone/tablet ergonomics. Older industrial resistive screens feel awful in 2026.
- 12V DC input means you can power it from the same buck converter as anything else on the wall.
- "Used" condition. Mine arrived with a few minor scuffs on the back chassis and a working PSU. Verify on arrival.
- VESA mounting holes are present on the back chassis but the listing doesn't specify the pattern. Mine appears to be a non-standard pitch around 200×100 — measure yours before designing brackets. The reference build doesn't use VESA at all; the panel sits in a wooden rabbet (see frame section below).
- The driver board sticks out ~1.5 cm beyond the back of the panel. Account for this in your enclosure depth.
- 1920×1200 isn't 1920×1080. Kinboard's CSS uses a 16:9-ish dashboard layout but renders fine at 16:10 — the slightly extra vertical space is welcome.

The Mele Quieter line is one of the few fanless mini PCs that runs Windows 11 well. Fanless matters for a kitchen wall — no airborne grease ingestion, no audible whir during the morning silence.
| Spec sheet | This build | |
|---|---|---|
| CPU | Intel N100, 4 cores, up to 3.4 GHz boost | Intel N150 (newer 2026 hardware revision) |

The shipping spec sheet at store.mele.cn lists the N100 CPU. The unit captured for this wiki reports an Intel N150 — Mele appears to have refreshed the silicon mid-cycle without renaming the SKU. Both CPUs are Alder Lake-N, ~25 W TDP, integrated UHD graphics. Performance for kiosk-browser duties is indistinguishable.
- Fanless. Single biggest reason. A kitchen kiosk that whirs is a kitchen kiosk that gets unplugged within a month.
- Tiny (131×81×18 mm) and 200 g. Mounts to the back of the frame with double-sided VHB tape — no metal brackets needed, just stick it on.
- 2× HDMI + USB-C means you have spare video outputs for development without unplugging the kiosk display.
- Auto Power On, Wake on LAN, PXE boot, RTC wake — all the stuff you need for "if power blips, come back up by itself."
- Windows 11 IoT LTSC is the killer feature for kiosk use. No forced feature updates, no Edge Bing nag dialogs, no Cortana. The unit ships with regular Win11 Pro; you upgrade to LTSC separately if you have an Enterprise license.
- VESA mount included in the box, though the reference build doesn't use it.
- Wi-Fi 5 only — no Wi-Fi 6 or 6E. For a kitchen wall a few meters from a router this is fine; if your access point is in the basement and the kiosk is on the second floor, run Ethernet.
- The eMMC storage is fast enough for boot but slow for sustained writes. If you do anything write-heavy on the box (recording, large local data), pop in an M.2 SATA SSD.
- US store ships from China; expect 1-3 weeks plus customs. Amazon DE has them with EU stock.
- The included 12V PSU has a fixed-length cable (~1.5 m). May need an extension for behind-the-frame routing.

The display sits in a custom-built oak frame on the kitchen wall, mounted in portrait orientation. The Mele PC and cabling sit hidden behind the frame; the LD2410 presence sensor sits on top.
Empty frame from a side angle, showing the rabbet that holds the panel and the L-brackets at the corners. Red/black wires at the top are the LD2410 sensor leads.
Same frame from above. The horizontal cross-bar at the top of the rabbet is what the panel rests against.
The frame was built by hand from solid oak to fit this specific 27" panel. Exact dimensions, joinery, rabbet depth, and backing material aren't documented here — anyone reproducing this build would size the frame to whatever panel they sourced. The photos show the general shape.
If you don't want to build a frame yourself, off-the-shelf options that work for this kind of build:
- A deep picture frame from IKEA's Ribba/Sannahed line, with the back cut to fit the panel
- A printed enclosure from a maker like SmartHomeKit or similar (search "tablet wall mount enclosure")
- Mount via VESA brackets directly to the wall and skip the frame entirely
The panel and the Mele PC each need their own 12 V DC supply. Both PSUs share a single Schuko outlet via a small power strip routed behind the frame. From the Mele:
- Video — HDMI (or DisplayPort via active adapter) to the panel
- Touch — USB-A to the panel's USB-B touch interface
- Sensor — USB-A → USB-UART → LD2410 leads (only if you've added the presence sensor; see Presence-Sensor)
On Windows 11, the panel reports as a generic HID touchscreen and works without a driver. If taps register a few pixels off:
- Settings → Bluetooth & devices → Touch → Calibrate the screen for pen or touch input
- Pick the right monitor if multi-display
- Tap the cross-hairs as instructed
For Linux: xinput_calibrator (X11) or libinput's calibration matrix in udev rules.
Approximate, based on the spec-sheet draw of each component (not measured at the wall):
- Mele Quieter 4C: ~7-12 W (idle to load)
- 27" panel at full brightness: ~54 W
- LD2410 sensor + USB-UART: <1 W
- Total when active: ~60-65 W
When the presence sensor blanks the display, draw drops to roughly the Mele's idle plus the panel's backlight-off standby. Actual numbers will depend on your panel and Mele's power profile.
