Femtofox is a Linux-based mesh development platform - a Raspberry Pi sized computer with onboard LoRa radio, capable of being run with only 0.3w, making it ideal for solar powered nodes.
The Luckfox Pico Mini is the postage stamp sized heart of the Femtofox - a compact and power efficient Linux board, running Foxbuntu, our own customized version of Ubuntu. Femtofox is an expansion of the Luckfox's capabilities, utilizing a custom PCB with a 30db LoRa radio (over 6x the transmit power of a RAK Wisblock or Heltec V3) to create a power efficient, tiny and highly capable Meshtastic Linux node.

- Features and Specifications
- Supported hardware
- Installation guide
- How to order
- DIY instructions
- USB configuration tool
- Building your own Foxbuntu image
- Tiny size (63x54mm for Femtofox, 65x30mm for the Smol Edition). Equivalent to a standard Raspberry Pi hat and Pi Zero respectively.
- Power efficient (~0.27-0.4w average, depending on radio and mesh congestion)
- Full Linux CLI (Ubuntu) via our pre-built Foxbuntu image
- Meshtastic native client support via SPI
- USB host support - attach USB peripherals
- USB wifi support
- RTC support for timekeeping
