Stamp

Seeed Xiao Form Factor DUELink Microcomputer

---

Overview

Stamp is a fingertip-sized DUELink microcomputer (24×18 mm) in the Seeed Xiao form factor. Plug it into a breadboard with male headers, surface-mount it using the edge pads, or drop it onto a Xiao-compatible carrier. An upgraded regulator lets it host a long chain of DUELink modules over its Downlink port.

Program it in the Arduino IDE, bare-metal C++, or drive it as a host from Python, JavaScript, .NET, or MicroPython.

Pick Stamp for compact projects where you need USB on the board itself. If you don't need USB, Stick is even smaller.

Key features • Seeed Xiao form factor • Downlink DUELink connector • USB-C connector • Surface mountable • 24x18mm Overall Dimension

🌿 Cables not included

Modules ship without cables to reduce waste. Some specialty boards include a USB cable; for the rest, see Cables to add cables to your order.

Commands

Commands this module accepts. See Samples for runnable code in popular host languages.

Function	Description
BtnLdr()	Returns 1 if LDR button is pressed.
DVer()	This driver version.

Peek under the hood

The script below is this module's driver — it teaches the hardware how to respond to the commands listed above. It ships pre-loaded from the factory; most users never need to open it.

On-Module Code

Code that runs directly on this module's MCU. See how On-Module Code allows modules to run standalone.

Script

This example runs using the default DUELink Internal Engine using its Scripting Language, and it expects the module's driver to be loaded first, see the Commands Tab.
