🔧 Built for Developers – Endless Possibilities!

With Femtofox, you have complete control over your project. It runs a custom-built Ubuntu 22.04 (Foxbuntu) that’s ready for Meshtastic, command-line tools, and custom menus. The board features rich I/O options, a powerful LoRa radio with adjustable output power, and an ultra-low power draw of just 0.3W at 3.3V or 5V, making it perfect for solar-powered and remote applications.

From mesh networking to robotics, IoT, automation, sensor projects, and beyond, what you build is entirely up to you!

✨ Key Features & Hardware:

✔ Ultra Low Power: Operates at only ~0.3W, perfect for solar and off-grid deployments.
✔ Compact & Lightweight: 63x54mm – About the size of a Raspberry Pi HAT.
✔ Full Linux System: Runs Foxbuntu (Ubuntu 22.04), a custom build ready for development also possible to run Buildroot for experienced developers
✔ Powerful LoRa Radio: E22-900M30S (SX1262) with adjustable transmission power (up to 30dBm / 1W) for long-range, stable communication.
✔ Ethernet Support: RJ45 Ethernet port for wired networking.
✔ USB-C Console Port (CH340): Built-in serial-to-USB converter – direct access to Linux via a USB-C cable.
✔ USB 2.0 Host & USB-C OTG: Connect keyboards, storage devices, or other peripherals.
✔ Extensive GPIO Access: Exposed GPIO pins, supporting:

UART for serial communication
I²C for connecting sensors and displays
SPI for fast data transfer
PWM & Digital I/O for custom applications

✔ Pre-Soldered GPIO Headers: No need for additional soldering – ready to use!
✔ RTC Support: Empty pad for a real-time clock (RTC) – optional for applications needing precise timekeeping.

📦 What’s Included in the Box?

✔ 1x Femtofox Board
✔ 1x E22-900M30S LoRa Module (pre-installed)
✔ 1x Luckfox Pico Mini A (pre-installed) ✔ 1x Pre-Soldered GPIO Header Set

❗ What You’ll Need (Not Included)

❌ No Antenna - You need an antenna tuned for 868MHz with an ipex connector. Do not use this with the antenna disconnected!
❌ No MicroSD Card Included – You must provide a microSD card (8GB–128GB max) and flash Foxbuntu to get started.
❌ No Cables Included – USB-C cables are not included.
❌ No RTC Module Included – Optional but recommended.
