Schematic Overview
SCHEMATIC CURENTLY UNAVAIABLE
Pinout Connections
I2C Display (OLED/LCD):
- PC0 → SCL (with pull-up resistor)
- PC1 → SDA (with pull-up resistor)
UART Serial Communication:
- PD0 → TX
- PD1 → RX
DS1302 RTC Module:
- PD2 → CLK
- PD3 → DAT
- PD4 → RST
Speaker/Buzzer:
- PD7 → +SPK (positive terminal)
- GND → -SPK (negative terminal)
Ensure your power lines are clean and filtered when dealing with sound or communication modules to avoid noise or instability.
