We updated the earlier date of end of January to March then April based on production schedule from factory.

The WisMesh 1W Booster Starter Kit brings more TX power and better reception to Meshtastic networks. Powered by the RAK3401 WisBlock Core module with the Nordic nRF52840 MCU and a RAK13302 1W LoRa transceiver module, mounted on a RAK19007 Base Board.

Unlike common solutions, the RAK13302 integrates a dedicated RF filter stage, which not only enables 1W high-power transmission but also significantly enhances receiver sensitivity. This means longer range, more stable links, and stronger mesh reliability. This is ideal for outdoor adventures, emergency communications, or wide-area IoT coverage, positioning it as some of the best hardware for long-range Meshtastic networks.

Notes: Transmit power limits and allowable frequency plans differ by country and region. This product supports high power operation, but users must configure transmit power, antenna gain, and frequency settings to comply with local regulations.

Due to the high power consumption of the 1W transceiver, the RAK13302 cannot work from the 3.3V supply voltage. It requires:

• Using a battery with the WisBlock Base Board
• External 5V supply for the RAK13302 module through its own power supply connector
• Always powering from USB

Why choose the WisMesh RAK3401 Booster Starter Kit for your Meshtastic network?

Whether upgrading a Meshtastic 1W node or building a fresh deployment, this kit is engineered specifically for users who need reliable, long-range mesh communication in off-grid, outdoor, or emergency setups. With a full 1 W LoRa transmitter (30 dBm) and an integrated RF front-end including the SKY66122 amplifier + filter, you gain up to several times the coverage of standard Meshtastic nodes.

The use of the nRF52840 MCU ensures modern BLE and firmware compatibility, while the WisBlock modular ecosystem allows you to expand with sensors, displays, trackers, or repeater nodes with ease.

Compared to typical Meshtastic kits (100-160 mW output) or DIY 1W builds (which may lack RF filtering or stability), this kit delivers a proven, stable high-power solution—all while managing power, heat and regulatory concerns in a single product.

Range & RF Performance: SX1262 + SKY66122 Amplified Path

The WisMesh 1W Booster Starter Kit delivers exceptional performance for users needing a long-range Meshtastic solution. This is done by combining the Semtech SX1262 LoRa transceiver with the Skyworks SKY66122 high-power amplifier and a dedicated SAW filter. Unlike typical high-power boards that boost TX but degrade RX, this filtered RF chain, including an RF filter and PA for improved receiver sensitivity, preserves receiver performance while increasing output power up to 1 watt. The result is a cleaner signal, reduced self-interference, and significantly stronger SNR across real-world deployments. Users can expect more reliable two-way links, improved packet retention at long distances, and stable mesh coverage even in semi-obstructed environments.

Power Requirements & Thermal Notes

The 1W RF stage in the RAK13302 demands a stable 5V supply, as 3.3V sources cannot deliver the surge current required for high-power LoRa transmission. For reliable operation, users should power the module through USB, a regulated 5V adapter, or the WisBlock Base Board’s battery system—especially when using an SX1262 1W LoRa module in continuous or high-duty-cycle deployments.

How the 1W RF Chain Works (nRF52840 → SX1262 → PA/Filter)

The WisMesh 1W Booster Starter Kit uses a staged RF architecture to deliver clean, long-range LoRa performance. The nRF52840 MCU manages firmware and communicates with the SX1262 transceiver, which generates the sub-GHz LoRa signal, making the architecture suitable for a nRF52840 Meshtastic deployment. That signal is then boosted by the SKY66122 power amplifier, a 1W SKY66122 LoRa amplifier module, and passed through an integrated SAW filter to remove noise and harmonics. This ensures both high transmit power and excellent receiver sensitivity, enabling stable two-way communication even at long distances, as shown in the diagram below.
