4.3 Interfaces
Reference circuit design shows the typical hardware connections for the module. Interfacing to the module
requires connecting to the signals provided on the GL5712 mPCIe connector as listed in pin description. Specific
interface connections are discussed in this chapter.

4.3.1 Interface to host MCU
SPI interface
A SPI interface is provided on the PCIe_SCK, PCIe_MISO, PCIe_MOSI, PCIe_CSN pins of the system connector. The
SPI interface gives access to the configuration register of SX1301 via a synchronous full-duplex protocol. Only the
slave side is implemented.

USB interface
GL5712 series modules support high speed USB interface with a built in TF232H chip convert SPI to USB, can be
connected to any USB host equipment with compatible drivers. The module can uses the USB signals through the
mPCIe interface.

4.3.2 Power pins
GL5712 series modules has multiple power and ground pins available on the mPCIe connector.
It is recommended that all power and ground pins be used when connecting to the module.

4.3.3 RF connection
GL5712 series modules have a U.FL connector for interfacing with an external antenna. For proper operation,
antenna selection must consider frequency band and impedance.

4.3.4 RESET pin
GL5712 series modules have an active-low reset input. Pulling this signal low during normal operation will cause
the module to execute a reset cycle.

4.3.6 RF enable
GL5712 series modules have an input signal used to enable the RF radio on the module. A low level on the
RF_ENABLE pin will disable all RF transmission and reception.
