Key Features

 The schematic includes all necessary components for powering, programming, and extending the functionality of the microcontroller. 

Microcontroller:

  ATmega1608 (U1) microcontroller serves as the core of the development board.

  Supports UPDI programming.

Power Supply:

  Powered via a micro-USB port (U13).

  Integrated 3.3V voltage regulator (AMS1117-3.3) to provide stable power for the system.

  Optional power fuse (F1, 500 mA) for overcurrent protection.

Programming and Debugging:

  UPDI programming header for uploading firmware.

  Serial-to-USB converter CH340C (U2) for UART communication and debugging.

  NOTE some PCS might need to install a driver to use the CH340C

Integrated Peripherals:

  Real-Time Clock (RTC): Includes a DS3231 RTC module for timekeeping applications, with a 32.768kHz crystal.

  Accelerometer: MPU6050 sensor (U4) for motion and orientation detection, interfaced via I2C.

Indicator LEDs:

  Power and activity LEDs for visual feedback.

  RX and TX LEDs for UART communication.

Logic Level Conversion:

  Logic converter for interfacing between 3.3V and 5V peripherals.

Breakout Headers:

  Exposes all microcontroller pins for easy prototyping and integration with external modules.
