I personally don't like these combined drives, all on one board.
A stepper driver is the weakest link in the CNC chain, fry one axis and the whole board is toast. Separate drivers are about £40 each for good ones with protected circuitry, the on board ones are very basic.

All this is in that box is a power supply, say £40 tops, 3 drivers £120 and a breakout board say £45 and that all components available in the UK so warranty isn't like having to send a box back to China and waiting God knows how long.

If you want an all on one board driver then DIY-CNC does one for £90 built and tested.
