RAK13302 WisBlock LPWAN Wireless Module (Board VD) Datasheet
Overview
Description
The RAK13302 is a LoRa module built around the Semtech SX1262 LoRa transceiver and the SKY66122 signal booster. It offers an easy-to-use, compact, and low-power solution for long-range wireless data applications.
Fully compliant with LoRaWAN standards, the RAK13302 also supports LoRa Point-to-Point (P2P) communication. It seamlessly integrates with LoRaWAN network servers, including The Things Network (TTN), ChirpStack, Actility, and more.
With its 1-watt signal booster, the RAK13302 is well-suited for applications that demand extended communication range.
The module is compatible with the RAK6421 RPi WisBlock HAT and WisBlock Base Boards, when used in conjunction with the RAK3401 WisBlock Core module.
This documentation is for the board version VD, which is the current production version.
The board version VD has different variants for power supply over external 5 V connector or internal battery. It is no longer possible to switch between the power supply options.
If you have a board version VC, use the datasheet for the VC version.

Specifications
Overview
Mounting
The RAK13302 WisBlock LPWAN Wireless Module can be mounted on the IO slot of the WisBlock Base Board. Figure 1 shows the mounting mechanism of the RAK13302 on a WisBlock Base board, such as the RAK19007.

The hardware specification is categorized into five parts. It shows the pinouts and their corresponding functions and diagrams. It also covers the RF, electrical, and mechanical parameters, which include the tabular data of the functionalities and standard ratings of the RAK13302 WisBlock LPWAN Wireless Module.
Chipset
| Vendor | Part Number |
|---|---|
| Semtech | SX1262 |
| Skyworks | SKY66122 |
Due to the high power RF signal output, the module requires power either through the battery on the WisBlock Base Board or from an external 5 V supply voltage.
Pin Definition
The RAK13302 WisBlock LPWAN comprises a standard WisIO connector. The WisIO connector allows the RAK13302 module to be mounted to a WisBlock Base Board, such as RAK19007. The pin order of the connector and the pinout definition is shown in Figure 2.
- SPI related pins, NRESET, ANT_SW，DIO1, BUSY, EX_5V, VBAT, 3V3, and GND are connected to the WisIO connector.
- EX_5V is for an external 5 V power supply for the booster.
- When supplying the WisBlock RAK13302 through an external 5 V power supply, it will power as well the base board, core module, and other modules. It will also recharge the battery connected to the base board.

Power Supply Variants
The RAK13302 version VD module has two hardware variants. One variant only works with an internal battery supply, while the other one only works with an external 5 V power supply. The different hardware versions are marked with different codes on the label.
The battery supply variant, which is powered through the battery connected to the WisBlock Base Board, has the code 001 on the label. It does not have a connector for the external 5 V supply on the bottom of the PCB.
Figure 1: RAK13302 Wireless Module Battery Supply IndicationThe external 5 V supply variant has the code 002 on the label. It has a connector for the external 5 V supply on the bottom of the PCB.
