That looks like a replace to me. The PCB is damaged quite a bit. If you need the stepper outputs, replacing that chip is unlikely to be successful.
If you have enough spare outputs that you can move the function to a different output, it might work to just remove that chip. Cut the legs with the smallest diagonal cutters you can find and then remove them one by one, or just cut flush to the PCB.
Looks like a DIY board with the connector screws and axial resistors. If so, our gutswap replacement deal doesn't apply.
If it was a fully assembled and tested purchase, email info@vems.hu including these pics and the serial number. They can give you a replacement cost.
Thanks,
