So far, I created the schematic for WakePad, a 4-key alarm clock macropad designed for my younger brother. I added the Seeed XIAO microcontroller, four mechanical switches, a 4-pin OLED connector, a 4-pin RTC connector, and a 2-pin buzzer connector. The switches are connected to separate GPIO pins, while the OLED and RTC share the I2C SDA and SCL lines. The buzzer is connected to a GPIO pin and GND. The next step is to fix ERC warnings, assign footprints, and start the PCB layout.
