Electrical Characteristics
The power requirements, port pinouts, GPIO characteristics, cable connections and wireless operational
modes are described below.
Power Input
Power to the SX-560 Module and the SX-560-6900 Evaluation Daughtercard is supplied through the
power jack, located at J6, at +5VDC ±10%. Use the included power supply or an equivalent +5VDC
power supply with a minimum of 1 amp capacity.
Power of +3.3VDC ±5% is supplied to the SX-560 Module via the I/O header, JP13.
