What is the High Power Module for LoRa?
The High Power Module for LoRa with SX1262 + SKY66122 Booster is a WisBlock add-on for extending Meshtastic, LoRa P2P, and LoRaWAN® links. It combines the Semtech SX1262 transceiver, SKY66122 RF front-end booster, and an integrated RF filter to provide hardware capability of up to 1W (30 dBm) output with improved receiver sensitivity.
The module mounts on a compatible WisBlock IO slot and adds higher-power radio capability to an existing WisBlock or WisMesh design. It is not a complete node; a compatible WisBlock Core, baseboard, antenna, and power source are also required.
Two versions provide the same RF performance but use different power arrangements:
- Battery Powered: An onboard boost circuit generates the amplifier’s required 5V from the baseboard supply.
- External 5V DC Input: The amplifier receives regulated 5V DC through a dedicated module connector.
Compatibility Note
Due to its higher power consumption, the RAK13302 High Power Module for LoRa requires a 5 V supply and cannot operate from 3.3 V alone. The module is available in two hardware versions:
- Using a battery with the WisBlock Base Board (recommended to have USB or Solar Charging 5V for continuous operation).
- External 5 V supply via its power connector
NOTE:
This changed from the previous version of the RAK13302 module, where you could select the power source. In the new hardware version, you cannot switch anymore between the two power sources; there are two different modules, one for battery supply and one for external 5V supply. Make sure you order the correct version.
This module is FCC-certified for operation in the US915 band. The current FCC-certified configuration has a maximum output of approximately 24.5 dBm (about 280 mW), which is below the 30 dBm hardware maximum. FCC ID: 2AF6B-13302. Due to transmission power restrictions in other regions (e.g., EU), the 863-870 MHz variant should not be used at the module's maximum output.
Why You Need the High Power Module for LoRa
The module helps maintain communication where standard-power nodes struggle with distance, terrain, sparse coverage, or obstructions. Its modular format also lets teams strengthen an existing WisBlock deployment without redesigning the complete node.
Why it’s useful:
- Fewer Coverage Gaps: Keeps distant or obstructed nodes reachable across demanding deployment areas.
- Simpler Upgrades: Adds higher-power communication without replacing the existing modular node design.
- Flexible Power Planning: Supports self-powered nodes and integrations with an available regulated supply.
- More Consistent Links: Reduces retransmissions and intermittent connectivity across weak communication paths.
- Expandable Deployments: Leaves room for sensors, positioning, and other WisBlock functions on one platform.

ESP32-S3 + Semtech SX1262 with high-power RF stage |
Uses SX1262 in newer boards. |
|
Supply Voltage |
Requires 5 V due to the high-power output stage |
Varies (often 3.3 V or battery) |
Mostly standard node voltage (3.3 V) |
|
Ecosystem Focus |
Modular upgrade path, WisBlock/WisMesh ecosystem, Meshtastic compatibility |
Dev-board approach, ESP32 + LoRa board, less upgrade, modular component focus |
Developer module board, IoT dev-board focus rather than high-power module |
|
Differentiators |
High-power module with hardware capable of up to 1W (30 dBm), receives boost and filter for better sensitivity, upgrade path for users already in the ecosystem |
Boards with 1W output exist, but may be less modular or less ecosystem-upgrade focused |
Strong dev-board environment, but not always 1W or upgrade-path module oriented |
|
Key Takeaways |
Best for modular, high-power deployments |
Better for prototyping, not scaling |
