Walnut Pi 1B — Industrial ARM Development Board, Quad-Core A55 1.5GHz, usb3.0, Ethernet, 1GB/2GB/4GB

The Walnut Pi 1B is a Linux-based development board driven by a 4 cores ARM A55 processor with a main frequency up to 1.5GHz, designed for high performance and flexible use. Memory options include 1GB/2GB/4GB (optional), and storage can be expanded with up to 64GB eMMC or Microed card expansion to cover a wide range of applications. Connectivity and expansion are extensive: multiple USB interfaces (including usb3.0), an Ethernet port, and a GPIO pin support connection to various peripherals. Thermal and reliability concerns are addressed with an aluminum heat sink design that improves heat dissipation and helps ensure stable long-time operation. The board runs a developer-friendly Linux environment and supports multiple open-source software packages and development tools to accelerate project development. Well suited for education, training, technology research and development, and prototyping production of innovative projects.
