Dev Kit Setup

Your kit arrives assembled, tested, and already flashed. From the box to your own words glowing on the panel is about five minutes, and everything happens in your browser — no app, no account, no cloud.

01

Step 1 — Power it on

Plug the panel into the included 5V USB-C supply. The panel announces its setup hotspot: JOIN ME → DEVMATRIX-XXXX (the Xs come from your board's serial).

⚠ Use the included power supply. A weak phone charger can brown the board out at full brightness — the firmware caps brightness for exactly that reason, and the Console warns you if a reset was a brown-out.
02

Step 2 — Join the setup hotspot

  1. On your phone, join the DEVMATRIX-XXXX Wi-Fi network the panel is showing.
  2. A setup page opens by itself. If it doesn't, browse to 192.168.4.1.
  3. The page scans and lists your networks live. Pick your 2.4 GHz network, type the password, and watch it join in real time — no blind reboot-and-hope.
✓ Wrong password? The page tells you and lets you retry — the device never reboots into limbo.
03

Step 3 — Open the Console

After joining, the panel itself shows the last step: WIFI CONNECTED · LAST STEP: OPEN DMX-XXXX.LOCAL IN YOUR BROWSER. Open that address — it's the Console, served by the device itself: live status, apps, a 64×32 paint canvas, brightness, updates, and settings. The phone that ran setup is already signed in.

⚠ Address not found? Some networks block local hostnames — use the IP address the panel showed during setup instead. Both work. And make sure your computer is on the same Wi-Fi as the panel.

Step 4 — Your first app, 30 seconds

Console → Apps → Messages → type your words → PUT IT ON THE PANEL. They're saved, enabled, and showing. From the same page you can turn on flights from your own ADS-B receiver, install live weather layouts, or run 1,000+ community Pixlet apps.

05

Step 5 — Pair your other browsers

On any other phone or laptop, open the panel's address and tap Pair. The panel shows a 6-digit code; type it into that browser and it's in. Reading the panel is the proof it's your device — nothing to write down, and a lost browser never means starting over.

06

Step 6 — Updates, and the floor under everything

Firmware updates upload from the Console's Deploy page and install over the air — the previous version stays in a second slot on the board. If an experiment ever goes truly sideways, double-press the board's reset button and it mounts as a USB drive you can drag known-good firmware onto. There is always a way back.

✓ Optional: point the device at your own MQTT broker (Console → Settings) and Home Assistant discovers it with zero YAML.
07

Going deeper — your device, my docs

The panel serves its own quick guide (Console → Guide), so the instructions survive an internet outage. The complete owner's manual — recovery and re-flash to default, MQTT and Home Assistant details, and the REST API — is right here: flighttrackerled.com/devkit/manual. Building the open firmware yourself lives with the source: request source access.

This is a self-serve developer product by design: the setup guide, the built-in Guide, and the manual are the support. I add real support capacity only if demand requires it.
