DRIVE PCB OVERVIEW
Figure 3: General Purpose Disc Pump Drive PCB interfaces
The General Purpose Disc Pump Drive PCB should be powered from a 3.5 to 5.5V supply, and can
be controlled over a UART connection. In addition, 3x analog inputs allow easy interfacing with a
variety of sensors, and allow the Drive PCB to perform closed loop control on board. Further still,
the board acts as an I2C master, allowing communication with a selection of digital sensors that are
relevant to many common applications for Disc Pump. Note that the PCB does not support I2C
control by another master device.
