OEM Header Interface
The OEM Header Interface is the primary method for communications between the SX-550 and your
device. It includes the necessary pins for serial data I/O, GPIO, and power.
Table 12 describes the OEM header interface pinout for the SX-550 module. Table 13 shows the OEM
interface signal descriptions. All input and output signals, except the differential signals, are 0 to 3.3V
logic signals.
