DIY Sandbox is proud to offer Platinum, an integrated "Arduino Mini" form factor microprocessor with an onboard 802.11b WiFi module and microSD card holder. Measuring less than 2" x 2" (with headers), Platinum offers a fully customizable low power WiFi solution in an extremely compact size.


Platinum is designed for advanced users. A basic understanding of soldering, reading schematics, and programming via an FTDI breakout board is required to use Platinum to its full potential.


Note: Programming your Platinum requires the use of an FTDI breakout board (example). In addition, we have provided detailed instructions on the programming process in our Platinum QuickStart Guide (PDF). Please follow all instructions in this guide to avoid common issues. In addition, we have provided a handy Pinout Guide (PDF) to help you easily indentify the various pins which are exposed for your use.
