The processors are the same, 16MHz, and one great advantage of these models is the high amount of IOs. The only difference between the Mega12 is the flash memory is bigger on the 2560. So, feeding the Arduino is already feeding the ESP, which is already down to 3v3, and internally that microcontroller is already 3v3. The power in the RobotDyn is 7 to 12 volts, and the ESP8266 is already powered, and already has a voltage reducer.

Alternatively it is possible to pass references to functions which read.

The pins to be used for the serial data (SDA) and serial clock (SCL) control lines can be defined at run-time. It utilises the pinMode (), digitalWrite () and digitalRead () functions. Keyestudio Mega 2560 R3 is a microcontroller board based on the ATMEGA2560-16AU, fully compatible with ARDUINO MEGA 2560 REV3.

This is wonderful, since the traditional Mega Arduino has only 256kb of memory. SoftWire is a software I2C implementation for Arduino and other Wiring-type environments. Crystal : It has a crystal circuit with two capacitors and one 16 Mhz crystal for xtal pins 1 and 2 interfacing with. The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. A push button is used to get 4 cycle low signal on reset pin to get the controller in reset mode. Reset : It has reset circuit with capacitor, button and resistor to reset the controller.

We can see, then, that the intention of the RobotDyn creaters was to maintain the architecture of the ATmega.Īs we see in the table above, the ATmega has 32MB of memory, not counting the ESP memory. Arduino Mega ICSP Pinout for ATmega 2560. I particularly like the more compact option, but the power is the same in both. However, in the RobotDyn, we have the mini-USB. We can see that they are similar, but in the 2560, we have the USB printer, which is a large connector. There are pin mappings to Atmega8 and Atmega 168/328 as well. Below is the pin mapping for the Atmega2560. Here, we have a comparison between the Mega Arduino with the integrated ESP (Arduino Mega RobotDyn) and the traditional Mega Arduino (Arduino Mega 2560). A diagram showing the correspondence between the pins on an Arduino board and those of the ATmega2560 microcontroller.
