No it is a intergrated design, it is all contained on one PCB.
Just for reference here is the two units I use to presurize the mines, one is a Schwinn frame pump and the other is a Co2 12gram powered bike tire inflator, both work well, and since my AT-4s and the Gustavs use 12grams I have those LBT fuse pouches on my gear so I have quick acess to the 12grms when reloading either the mines or the shoulder fired units. 12 guage shot shell loops also work excellent to carry 12grams. The Frame pumps fits perfectly in a pop flare pouch I use a LBT one, but BHI also works, and the Co2 Inflator fits into a pistol mag pouch securely.
