From the project

Tensile testing machine

The EdgeBoard is the main controller PCB for the MaD tensile tester. It hosts the Parallax Propeller 2 microcontroller and carries all of the machine's I/O.

- Propeller 2 microcontroller (the firmware in Firmware/MaDCore runs here). - Servo / stepper driver interface for the motion axis. - Encoder input for position feedback. - Endstops and the door interlock / ESD safety chain. - SD card (tests run autonomously from G-code stored here). - Host USB-to-serial link (2,000,000 baud) for the control app. - Header for the DS2 Addon force-gauge interface.
