Abstract
In one example in accordance with the present disclosure, a fluidic ejection controller is described. The fluidic ejection controller includes a firing board to pass electrical control signals for ejecting fluid from a fluidic ejection device. An ejection board of the fluidic ejection controller is electrically coupled to, and selectively removable from, the firing board to pass the electrical control signals to the fluidic ejection device. Electrical pins are disposed on the ejection board in a pattern that matches a pattern of electrical pads on the fluidic ejection device. The electrical pins interface with corresponding electrical pads to pass the electrical control signals from the ejection board to the fluidic ejection device.
