RP2040 Meshtastic Nibble + BME280 Sensor Kit

RP2040 Nibble – The Ultra Low‑Power Meshtastic Node

The RP2040 Nibble is a Meshtastic node kit debuted at 38C3 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 RP2040 Nibble is the perfect solution for power‑sensitive projects and energy‑efficient mesh networking, thanks to the ultra‑efficient Raspberry Pi RP2040 chip.

This kit is tailored for those who need minimal power consumption without compromising on robust, long‑range communication. 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.

Key Features

• Energy Efficiency: Designed with the RP2040's low‑power consumption in mind, this build is ideal for solar‑powered setups and power‑constrained projects.
• 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 (available in 868MHz or 915MHz), ensuring encrypted communications over long distances.
• Customizable Expansion: Equipped with dedicated I²C and SPI pads for easy integration of additional peripherals.
• Included Environmental Sensor: Includes a BME280 sensor for precise tracking of temperature, humidity, and barometric pressure—great for environmental monitoring.
• Effortless Firmware Updates: Enjoy a smooth setup with drag‑and‑drop pre‑compiled Meshtastic firmware, updated via USB.
