JadeNode Build (~$50)

The JadeNode is CascadiaMesh's most cost-effective DIY repeater design, purpose-built for the Pacific Northwest's 910.525 MHz band. At roughly $50 in parts, it's an accessible entry point for community members who want to extend network coverage without a large investment.

Parts List

Key Design Choices

• nRF52840 + Wio SX1262: The nRF52840 microcontroller paired with the Wio SX1262 LoRa module provides excellent power efficiency. nRF52-based devices have significantly longer battery life than ESP32-based alternatives, making this design well-suited for solar-powered deployments with limited panel size.
• PeakMesh charging board: Sourced from David on Etsy, this charging board is recommended by the CascadiaMesh community for better winter solar performance compared to generic MPPT modules.
• IP65 enclosure: The 158×90×60 mm ABS box provides weather protection suitable for outdoor permanent deployment.
• Linx ANT-916-CW-HW-SMA: A tuned antenna at 916 MHz, close enough to 910.525 MHz for good performance. Available from Digi-Key with reliable stock.

Firmware

Flash with MeshCore Repeater firmware using the MeshCore Web Flasher. After flashing, configure via the MeshCore Repeater USB Setup tool:

• Frequency: 910.525 MHz
• Bandwidth: 62.5 kHz
• Spreading Factor: SF7
• Coding Rate: 4/5
• Zero Hop Interval: 0
• Flood Advert Interval: 48 hours

Do not include "Repeater" in the node name - it wastes airtime on every advertisement.

Notes

• This build does not use a bandpass filter. For most residential and semi-rural locations, interference is not a significant issue with the nRF52/SX1262 combination.
• If deploying in a high-RF-noise urban environment, consider upgrading to the Raccoon Tree Node or Ikoka Box designs which include filter options.
