![]() ![]() Suitable for low cost and communication demand of hobbyistsĭFRduino Mega has 54 digital pins and 16 analog pins, 4 UART channels. Mega 2560 has 256KB FLASH, two times of Mega1280, which could offer a larger create space for your projects.ĭFRobot Arduino Compatible Microcontrollers SeriesĪrduino UNO R3, suitable for Arduino beginners and hobbyistsĭFRobot Leonardo is a low-cost controller, integrated with Xbee and SPI. You can simply power it with a USB cable or a standard adapter or use a battery as external power. ![]() ![]() External Interrupts: 2 (interrupt 0), 3 (interrupt 1), 18. Define the interrupt pin with a pullup, and pin 13 as an output: on the Arduino Uno: (pinmode 2 2) (pinmode. The board comes with a bootloader that enables users to download programs directly via a USB. Pins 0 and 1 are also connected to the corresponding pins of the ATmega8U2 USB-to-TTL Serial chip. Arduino Mega 2560: between pin 21 and GND. It features 54 digital I/O ports, 16 analog signal input ports, 4 UARTs(hardware serial ports), and a 16MHz crystal oscillator. What’s more, DFRduino Mega2560 can work steadily even when only powered by a 3.7V lithium battery.ĭFRduino Mega2560 is an ATmega2560-based microcontroller that provides full compatibility with "Arduino MEGA2560“. In addition to optimizing the overheating issue, it offers a wider input voltage range. Therefore, the speed of the Mega cannot keep up with the frequency of steps from the encoders. Arduino Mega Pinout Voltage Regulator-The voltage regulator converts the input voltage to 5V. It has a crystal oscillator-16 MHz, a power jack, an ICSP header, a USB-B port, and a RESET button. The new version of DFRduino Mega2560 has improved the VIN power supply circuit by changing the easily overheat LDO to DC-DC circuit for ensuring safety and reliability in long-term use. I was trying to setup an Arduino Mega 2560 using the interrupt pins and this library as an odometry node in ROS however, I realized I made a miscalculation in my gear ratio. Here you will find all of the technical documentation and support files for the Arduino Mega 2560 Revision 3. Arduino Mega 2560 has 54 digital input/output pins, where 16 pins are analog inputs, 14 are PWM pins, and 6 are hardware serial ports (UARTs). ![]()
