# Femtofox &nbsp;&nbsp;&nbsp;<sub><sub>The tiny, low power Linux Meshtastic node
**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 a 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.
