Serial Device Explorer

Browse a registry of known serial device profiles — vendor IDs, product IDs, baud rates, typical use cases. Then connect a real device and inspect its port capabilities live.

◉ Now works on Android — Chrome 148+

Known Device Registry

Select a profile to pre-fill connection settings, then connect a real device.

Port Capabilities — port.getInfo()

usbVendorId — not connected —

usbProductId —

Matched profile —

Port state closed

Baud rate —

Platform —

Connection Tester — send a probe command and read back the response

— connect a device to send probe commands —

// Web Serial API — same code works on desktop AND Android Chrome 148+
const port = await navigator.serial.requestPort();
const info = port.getInfo();
// { usbVendorId: 0x2341, usbProductId: 0x0043 }  ← Arduino Uno R3

const knownDevice = REGISTRY.find(d =>
  d.vendorId === info.usbVendorId &&
  d.productId === info.usbProductId
);

await port.open({ baudRate: knownDevice?.baudRate ?? 115200 });
// Now read/write as normal
