9 volt DC, regulated, 2 A AC adapter. Accepts worldwide 100 V - 240 V input and has a US/Canada style plug. For output, it has a center positive 2.1 x 5.5 mm output barrel plug. This is the same power supply included in the WaterColorBot kit; an excellent choice for use with the EBB motor controller.
A through-hole pcb-mount jack (receptacle) is available separately here, in case you plan on adding this to a circuit board.
