Arduino Mega 2560 R3

From the shop's description

The Mega R3 is backwards compatible with the arduino mega - same driver, same uploading, same look and work with the existing shields but can adapt to new shields. Description The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. Arduino Mega 2560 Rev3 Overview: – Operating voltage: 5V – Input voltage (recommended): 7-12V – Input voltage (limits): 6-20V – Digital I/O pins: 54 (15 of which with PWM output) – Analog Input Pins: 16 – DC current per I/O pin: 40 mA – DC current for the 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 For Standards Arduino Mega Features, Please click here Documents Arduino Home Page Programming Reference Download the Arduino Software
