A high-performance microcontroller board built on the ATmega2560, featuring extensive I/O options for complex robotics and embedded projects.
Technical Specifications
- Microcontroller: ATmega2560 @ 16 MHz
- Memory: 256 KB Flash (8 KB used by bootloader) | 8 KB SRAM | 4 KB EEPROM
- I/O Pins: 54 Digital I/O (15 PWM outputs) | 16 Analog Inputs
- DC Current Limits: 40 mA per I/O pin | 50 mA for 3.3V pin
Power Supply & Operating Voltage
- Operating Voltage: 5V
- Input Voltage: 7–12V (Recommended) | 6–20V (Limits)
- Power Source Selection: Automatic between USB and external power (DC Jack or VIN).
Power Pins
- VIN: Input for external DC power, or output when powered via DC jack.
- 5V / 3.3V: Regulated power outputs (3.3V max draw: 50 mA). Avoid supplying unregulated power directly to these pins.
- GND: Ground pins.
- IOREF: Voltage reference pin to allow connected shields to adapt to the board's 5V operating level.
