A fully configurable active load & A small format 48V stepper motor driver

We are students of the National Technical University of Athens, working in the Electronics Lab. We are applying for a couple of projects related to our diploma thesis. 

Active Load

Microcontroller controlled, fast response active load capable of 500W dissipation with any V/I characteristic. USB capability and display.

Stepper Driver

DRV8711 based open source hardware solution, capable of 48V bus voltages and 5A+ steppers. Fully configurable through USB port, isolated step / direction / enable / fault connections. Pckaged to allow easy packaging of multiple modules, to be integrated in the lab's CNC router.

We have used Pcbway in the past through the lab's account. We believe your company offers the best quality / price among all prototyping services at the moment. Your help in those two projects will be greatly appreciated.
