KL-B25 or C11g Breakout board?

[technosteve]

I just ordered the KL-B25 Breakout board from Keling, but I'm wondering if I should have gone with the C11g board. The only difference that I can tell is that the C11g has a couple of relays and a charge pump. I don't plan on using the relays, but like the idea of the charge pump. Is this worth the extra $80? Will geckodrives even work with the KL-B25 breakout board?

I'm using 4 Nema 34 - 640oz steppers with G203v drives.

Thanks!

I used the C11G in my CNC mill retrofit.
It has the charge pump, one solid state relay, one mechanical relay and a variable speed control to hook my DC spindle driver to.
Made sense to me to buy this board instead of trying to add all these features later with additional boards.
