ESP32s3 Meshtastic Nibble + BME280 Sensor Kit

An all-in-one bundle for building a feature-packed Meshtastic node + environmental sensor add-ons.

The ESP32s3 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 ESP32s3 Nibble is the perfect solution for maximizing power and connectivity to be a perfect mobile node. The ESP32s3 Nibble can connect to your phone wirelessly to Meshtastic and used as a client, but can also be connected to your home Wi-Fi.

Key Features

• Robust and Powerful: Utilize the ESP32s3's wide range of features to create the perfect portable Meshtastic node.
• 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 or update your Nibble node wirelessly with web-flashing options using it's Bluetooth and Wi-Fi compatibility.
