ACS711 Demo Board User Instructions • The following picture is the top view of the demo board with explanations pointed to each test point hook up and socket pin, and the connection diagram in a typical application. • On board 3.3V voltage regulator U2 input voltage (Vin) range: 3.5-16V. • No external pull up resistor is needed for Fault pin as a 10k pull up resistor is already installed on board. • Once the sensor faulted (Fault signal went low and Fault LED lights on) the only way to reset the fault is to reset Vcc. • See ACS711 Data Sheet for detailed information. See next page for board schematic. Vin (3.5-16V) GND Viout Fault LED Fault Load Source
