RAK4631 Meshtastic Kit - SX1262 RAK19007 Base Board with Antenna
$79.99
RAK4631 Meshtastic Kit (SX1262 LoRa + nRF52840)
The RAK4631 Meshtastic Kit is a professional-grade LoRaWAN and Meshtastic-compatible developer set designed for long-range wireless communication. This kit combines the RAK4631 WisBlock Core—which features a high-performance Nordic nRF52840 MCU and a Semtech SX1262 LoRa transceiver—with the RAK19007 WisBlock Base Board. It is optimized for ultra-low power consumption and is factory-preloaded with Meshtastic firmware for out-of-the-box mesh networking capabilities in the 868MHz and 915MHz bands.
Product Features
- Dual Wireless Connectivity: Features LoRa for long-range data (up to 15km+) and Bluetooth Low Energy (BLE 5.0) for easy configuration via smartphone.
- Meshtastic Ready: Specifically designed for off-grid mesh networks; allows for decentralized text messaging and GPS tracking without cellular service.
- WisBlock Ecosystem: Modular design allows for the addition of GPS, sensors, and displays via simple plug-and-play IO slots.
- Ultra-Low Power: Engineered for battery and solar applications, with deep sleep currents in the microamp range.
- SX1262 Transceiver: Higher efficiency and improved receiver sensitivity compared to older SX1276 modules.

Antenna Installation & Safety
- LoRa Antenna: Must be connected to the IPEX connector labeled "LoRa" or "ANT" before powering the device. Operating without an antenna will damage the SX1262 chip.
- BLE Antenna: The nRF52840 requires the smaller internal antenna for Bluetooth pairing with the Meshtastic mobile app.
- Mounting: Use the included screws to secure the RAK4631 to the RAK19007 base board to ensure stable electrical contact during vibration.
