Hardware Overview


  1. Click here to login or signup to mbed
  2. Import the mbed_blinky program
  3. Click the Compile icon of the top toolbar to compile the program, then download a compiled hex file.
  4. Drag-n-drop the downloaded bin file into the mbed disk
You can open main.cpp to change the program. For example, use the following code to blink the LED every 0.1 second
#include "mbed.h" DigitalOut led(LED1); // on-board led is connected to D13 int main() { while (true) { led = !led; wait(0.1); } }


To enable SWD debug or to get debug message through USB Virtual serial, please install a driver from mbed.

Update or Restore Firmware

The latest firmware version for the Arch Max is v0203 built at Oct 8, 2014. To check your firmware version and built date, open the mbed.HTM file of your mbed disk in a text editor.
  • Press and hold the Arch Max’s button to power it on.
  • A CRP DISABLD disk will show
    • On Windows, replace firmware.bin with the above firmware
    • On Linux/Mac, enter command: dd if={new_firmware.bin} of={firmware.bin} conv=notrunc


Help us make it better

Thank you for choosing Seeed. A couple of months ago we initiated a project to improve our documentation system. What you are looking at now is the first edition of the new documentation system. Comparing to the old one, here is the progresses that we made:
  • Replaced the old documentation system with a new one that was developed from Mkdocs, a more widely used and cooler tool to develop documentation system.
  • Integrated the documentation system with our official website, now you can go to Bazaar and other section like Forum and Community more conveniently.
  • Reviewed and rewrote documents for hundreds of products for the system’s first edition, and will continue migrate documents from old wiki to the new one.
An easy-to-use instruction is as important as the product itself. We are expecting this new system will improve your experience when using Seeed’s products. However since this is the first edition, there are still many things need to improve, if you have any suggestions or findings, you are most welcome to submit the amended version as our contributor or give us suggestions in the survey below, Please don’t forget to leave your email address so that we can reply.
Happy hacking
