This is a software package for a 2-player board game Reversi, that can be played through wifi and controlled through a keyboard. This includes a library for the UART communication, the game logic, and interfacing with the wifi card.
The block diagram below outlines the interface between the microcontroller and each peripheral.
The schematic below shows the pinout and a few basic voltage dividers to step a 5V signal down to a 3.3V signal for the microcontroller and SD card reader to use.
