Open Source Nibble – The DIY Meshtastic Node Kit The Nibble is a Meshtastic node kit debuted at the 38th Chaos Communication Congress to accompany the talk by Kody Kinzie, which you can watch here: "Hacker's Guide to Meshtastic: Off-Grid, Encrypted LoRa Meshnets for Cheap!" The Nibble is the perfect beginner-friendly node for learning about Meshtastic, and it allows you to select one of two microcontrollers: the RP2040 and the ESP32s3. You can buy one in a few ways: PCB Only - Buy just the PCB and source the parts yourself! Unsoldered Kit - Everything you need to solder your own together Fully soldered kit - Fully assembled nibble, flashed and tested For projects that don't require a Wi-Fi or Bluetooth radio, the RP2040 Nibble provides significantly longer runtime, and is able to run on lower voltages. If you're planning on working with an iPhone or need Bluetooth/Wi-Fi for your project, stick with the more powerful esp32s3 Nibble instead. Check out the assembly video here: Key Features Compact & Rugged Design: The PCB fits snugly into a 25mm (1 inch) PVC pipe or 3d printed enclosure, (https://www.thingiverse.com/thing:6461262) making it perfect for outdoor and remote deployments. Reliable LoRa Communication: Comes with an RFM95 LoRa radio supporting 868MHz or 915MHz, ensuring encrypted communications over long distances. Customizable Expansion: Equipped with dedicated I²C and SPI pads for easy integration of additional peripherals. Effortless Firmware Updates: Enjoy a smooth setup with pre‑compiled Meshtastic firmware updated via USB.
