Looking for an off the shelf PCB.

I'm looking for a board that runs two Polulu A4988 stepper drivers (12v1.5a each) and a 5v300ma PWM from an Arduino-programmable chip. Having Wifi and a micro SD card reader would be a big plus. (ESP8266 would be acceptable). I'd also like a 12v screw terminal to power the whole thing. I need a USB connector for flashing bootloader and arduino programming. don't care what model.
Do you know of such a board in the wild?
Thank you!

You can also try stacking a few Arduino Shields together. A Stepper shield on a Wireless shield should get you the Pololu and wifi/microsd capabilities, and a Proto shield on top with a simple high power transistor circuit would get you the PWM output. You can use Wingshields for the screw terminals

I believe when I checked it last the pins conflicted.

way too specific, just like any electronics project, you just need to either make one, or use a through hole board and wire everything together, if you dont want to go through the process of building a pcb board, just go to your local electronic scrap store or frys, and get a through hole board and get a size that fits your needs
