Atmega16U2 Mega 2560 R3 Improved Version CH340G + Cable for Arduino Mega 2560 + transparent acrylic case for Arduino Mega 2560

The ATmel MCU ATMEGA16U2 MEGA 2560 R3 Improved Version CH340G Board is a microcontroller board based on the ATmega2560. Here are its key features:

1. Microcontroller and Connectivity:
– Powered by the ATmega2560 with 54 digital input/output pins (15 PWM outputs), 16 analog inputs, and 4 UARTs for hardware serial communication.
– Equipped with a USB host interface using the MAX3421e IC, enabling connectivity with Android-based phones.

2. Hardware Components:
– 16 MHz crystal oscillator ensures reliable clocking.
– USB connection, power jack, ICSP header, and reset button for versatile functionality.
– Improved version (R3) features enhanced pin-out with added SDA, SCL, and IOREF pins for shield compatibility with different voltage levels.
– Stronger RESET circuit for enhanced stability.

3. Revision 3 Enhancements:
– Added SDA and SCL pins near the AREF pin for shield adaptation to various voltage levels.
– IOREF pin for compatibility with boards operating at different voltages (e.g., AVR at 5V and Arduino Due at 3.3V).
– A reserved pin for future purposes.

4. Power Options:
– Can be powered via USB connection or an external power supply.
– Automatically selects the power source.
– External power can come from an AC-to-DC adapter (wall-wart) or battery, connected through the power jack.
– Battery leads can be inserted into the GND and Vin pin headers of the POWER connector.

5. Android Accessory Development Kit (ADK):
– Compatible with the Mega Arduino R3 ADK.
– Can be powered through the USB connection or external supply.
– USB Host functionality enables the phone to draw power (500mA total) from the board for charging when needed.

The ATmel MCU ATMEGA16U2 MEGA 2560 R3 Improved Version CH340G Board offers an array of features, including enhanced pin-out, stronger RESET circuit, and compatibility with various power sources, making it suitable for diverse electronics and development projects.
