02 / CONNECTION

## Match the interface. Then connect the equipment.

Match physical interfaces and application protocols separately.

01 

### SPI host connection

Mini-PCIe describes the form factor; data uses SPI, and the host must support full-duplex SPI.

02 

### Timing and control

Supports external GPS PPS input, active-high reset and RX\_ON / TX\_ON / CFG\_ON status signals.

03 

### RF connection

Uses a first-generation I-PEX connector; match the antenna band to the module model and deployment region.

For terminal positions, wire assignments and installation, follow the [official wiring instructions](https://package.think-link.net/manuals/pmc51x/pmc51x-manual-en.pdf)  .

03 / CONFIGURATION

## Choose a configuration that fits your site.

01 PMC514-433-N: EU433; PMC514-470-N: CN470.

02 PMC518-868-N: EU868; PMC518-915-N: AS923 / AU915 / US915 / KR920.

03 The 4 / 8 in PMC514 / PMC518 identifies the frequency family, not the number of channels.

04 A pin-compatible SX1303 is available as a custom option; the module requires a host and gateway software.
