    To etch fast, use warm water to make a solution with Ferric Chloride and shake(gently) the clad(by attaching it through a 'Grip' made by a PVC wire) or shake gently the plastic container of solution.

    We will not be selling this , we are working on a new L298 shield and will release it soon after testing. You can DIY or buy from us.


    The above shield you can DIY for about 150 bucks max.
