The Quantum Tiny Linux Development Kit 🚀 is composed of a compact System‑on‑Module (SoM) 🧩 and a matching carrier board 🔌 for expansion. The SoM, Quark‑N ⚡, is built on the Allwinner H3 platform 🖥️, featuring a quad‑core Cortex‑A7 processor 💪 and an ARM Mali400 MP2 GPU 🎮. The carrier board, Atom‑N 🔧, exposes a row of golden‑finger expansion pins ✨, enabling access to essential interfaces such as SPI, I2C, UART, GPIO, and more. Despite its size, the kit is designed as one of the smallest Linux development platforms 🌱 available, making it well‑suited for applications like a personal server 🌐, an intelligent voice assistant 🎤, or robotics development 🤖. Features ⭐ Ultra‑small (31mm × 22mm) 🧩 and highly integrated quad‑core Cortex‑A7 Linux SoM ⚡. Expansion board (40mm × 35mm) 🔌 with rich peripherals and interfaces: microphone 🎤, gyroscope 🌀, accelerometer 📈, 4× buttons 🔘 (GPIO‑KEY, Uboot, Recovery, Reset), and a TFT display 📺. Integrates a complete ARM‑Linux system 🐧 for advanced development. Ability to design your own baseboard 🛠️ thanks to the M.2 interface. Suitable for applications such as personal servers 🌐, voice assistants 🎧, and robotics development 🤖. Description 📘 The Quantum Tiny Linux Dev. Kit ⚙️ is possibly one of the smallest Linux development boards 🌍 on the market — a highly integrated kit with a quad‑core CPU 💪 capable of running Linux at only 40mm × 35mm 📏, including network connectivity 🌐. It is suitable for scenarios such as personal servers, voice assistants, and robotics development. The updated new version 🔄 improves wireless performance with a redesigned antenna, optimizes PCB layout by moving fan solder joints to the top, and removes the Uboot and Recovery buttons. The SoM, Quark‑N ⚡, is based on the Allwinner H3 platform 🖥️ with a quad‑core Cortex‑A7 CPU 💪 and ARM Mali400 MP2 GPU 🎮. Its 6‑layer high‑density gold PCB ✨ integrates a complete ARM‑Linux system 🐧 (CPU, DDR, eMMC) in a compact 2×3 cm footprint 📏. Most GPIO pins are exposed through the M.2 Key‑A golden‑finger interface 🔌, simplifying custom baseboard design. The carrier board, Atom‑N 🔧, connects to Quark‑N through the M.2 interface. Atom‑N exposes golden‑finger pins ✨ for I/O expansion, including SPI, I2C, UART, and GPIO. It also includes a microphone 🎤, MPU6050 motion sensor 🌀 (accelerometer + gyroscope), 4 onboard buttons 🔘, an IPS display 📺, and Wi‑Fi/Bluetooth connectivity 📡 — greatly expanding development possibilities.
