Small Size, Huge Performance Our VC21 series (powered by the popular Freescale Semiconductor 266MHz ARM926EJ-S™ i.MX21 processor) is based on the stackableVCMX212 single board computer (shown below), less than half the size of a business card. This computer can be used as a standalone device or enhanced by any number of our daughter boards. Everything from cameras, touch screen LCDs, sound cards, solar panels, GPS, Bluetooth, FPGA, ethernet, USB, motor controllers and memory cards can be stacked together to quickly develop your application. Even designing your own custom daughter boards is made easy with our open documentation.
