A custom-designed single-board computer built with RP2354B MCU. This project serves as a hardware platform for my experimental operating system. In its form it was inspired by the original Raspberry Pi SBC. However, it features an MCU that is much more managable in terms of low level development, as it is provided with comprehensive datasheet covering all details. Additionally, the board includes hardware interfaces (VGA, PS2, microSD) specifically selected for their simplicity in driver implementation. The board also features Ethernet chip by WIZNet and slot for soldering Raspberry Pi Radio Module.
This repository contains the hardware design files (KiCad schematics, PCB layout, BOM).
