Overview

The overview presents the top and back views of the RAK19713 board along with the block diagram describing its internal components.

Board Overview

The RAK19713 is a compact Mini PCIe module for low-profile, high-performance LoRa integration. The top of the board hosts the RAK4630 module, providing both MCU and LoRa radio functions. It includes USB and UART interfaces for communication, programming, and debugging. The bottom side has an unpopulated J-Link interface for a 5-pin connector (RST, GND, CLK, DIO, 3V) usable with a J-Link or RAKDAP1.

Block Diagram

The RAK19713 card integrates one RAK4630 module which represents the core of the device. This provides a Nordic nRF52840 microcontroller attached to a Semtech SX1262 radio. Additional signal conditioning circuitry is implemented for PCI Express Mini Card compliance, and two UFL connectors are available on the module itself for external antennas integration.
