If you have the RAMPS, and drivers the least expensive thing is to looking the GRBL for ramps. But you could reuse the drivers off the ramps setup with a $10 uno and a $11 cnc V3 shield

The shield has the exact stepper header connections, so the original cables would connect. No soldering. You could splurge and spend $3 more and get 4 drivers with the shield.

If you want to add auto on/off router control, the add a $6 one or two channel relay if you don’t mind some wiring.
