Mega 2560 R3 ATmega2560-16AU Board + USB Cable for Arduino -Black+Blue
Brand N/A Model 2560 R3 Quantity 1 Color Black + blue Material Heavy gold plate Features Arduino Mega is a ATmega2560 as the core of microcontroller development board£¬ itself has 54 set of digital I/O input/output end (14 groups can do PWM output)£¬ 16 groups of simulated than the input£¬ four groups of UART (hardware serial ports)£¬ use the 16 MHz crystal oscillator. Specification Operating Voltage: 5V; Input Voltage (recommended): 7-12V; Input Voltage (limits): 6-20V; Digital I/O Pins: 54 (of which 14 provide PWM output); Analog Input Pins: 16; DC Current per I/O Pin: 40 mA; DC Current for 3.3V Pin: 50 mA; Flash Memory: 256 KB of which 8 KB used by bootloader; SRAM: 8 KB; EEPROM: 4 KB; Clock Speed: 16 MHz Application Learning board; development board Other Power supply design Arduino Mega power supply system£¬ there are two options£¬ the USB power supply directly or external power supply. The choice of power supply will automatically switch. The external power supply can choose AC - to - DC adapter or battery£¬ the limits of the control panel for the 6 v to 12 v voltage range£¬ but if the voltage is less than 6 v£¬ I/O mouth may not be able to provide to 5 v voltage£¬ so will appear unstable; If the voltage is greater than 12 v£¬ voltage stabilizer will likely overheating protection£¬ are more likely to damage the Arduino MEGA. Therefore suggested operating power supply of 6.5 ~ 12 V£¬ recommend the power is 7.5 V or 9 V.
