Boston Engineering FlexStack™

FlexStack logoFlexStack™ is a full-function embedded computing platform that is small, battery powered and is ideal for both prototyping and production use. FlexStack empowers your company to jump-start the product development process; its modular design allows peripherals to be added simply by adding boards to the stack. FlexStack provides a hardware platform that easily migrates from prototype to production thanks to its small and flexible form factor that meets the needs of many small and low powered devices.

The FlexStack can be used in high vibration environments, making it ideal for remote sensing and data collection applications. Its compact size makes it easy to package FlexStack inside watertight enclosures allowing it to be used in the harshest of environments.

Modules available are: Power, CPU, DAQ, Bluetooth, FPGA, Communications, ADuC7026 Board, Audio Board and a Breakout board.
