The ELFSHL1 is compact carrier board/shield and when connected to 3 ELFDRV3 makes it the most compact and cost effective solution to drive a CNC machine. Its modular design makes it a versatile, flexible and maintainable solution that can discreetly drive any entry level and semi-professional 3 axis CNC machine. The whole driving solution (controller, shield and driver) will fit in a 60mm x 60mm x 60mm cube.

Features
- Capable of driving up to 3 ELFDRV1s, ELFDRV2s or ELFDRV3s micro-stepper drivers with indexer.
- On board thermistor based on the LM75B for active thermal control.
- 2.5 A fan driver.
- I2C expansion bus interface to chain other devices such as IO expansion boards, additional thermistors for off board temperature monitoring, LCDs, LED drivers, etc.
- 3 broken out general purpose IOs or analog inputs, user defined.
- +12 V input supply that can power both the mother board/shield and micro-controller.
- Compatible with the vinciDuino, Arduino UNO Rev3 and Arduino Leonardo.
- Breadboard friendly.
Combined with the vinciDuino or any compatible Arduino makes it an ideal and compact solution for driving a CNC machine in a 53mm x 53mm footprint.
