The voltage regulator allows to use up to 18V as an input value, however we do not recommend exceeding the recommended values aforementioned, since this can lead to excessive heat and damage the device. The maximum output current for 5V is around 800mA, while for 3.3V it is about 800mA. The used voltage regulator operates in a range of 6 to 9V DC. The board can be powered directly through the Micro USB connector, or via the corresponding contact on the board (Vin). ![]() The board has a Micro USB connector that allows you to connect the microcontroller to the computer via the USB-UART adapter CH340(A driver installation may be required).Ĭonnectivity to the computer is provided through the common micro USB connector (universally used by most phones, including Android smartphones). Even though it is an Embed board, it is solid stable as the Mega Board. ![]() The Mega Pro Embed functionalities are identical to the Arduino Mega 2560. The board has a compact form factor of 38X55mm and is an excellent solution for developing projects based on ATmega2560. It uses the original chip, and a 16 MHz high-quality quartz resonators is present on the board. The board is compatible with Arduino Mega 2560. I use cheap arduino rs485 module in the project. Pin 8 of Arduino Mega and Arduino Pro Mini is used to control the RE(Receive Enable) and DE(Data Enable) pins of MAX485. Arduino Pro Mini has only one Serial channel so i am using it in my application. Hello I am just wondering, 'How do I connect and code the DFPlayer Mini to play a sound with an Arduino Mega 2560' May someone, please, tell me how to do this My attempt with someones wiring diagram seemed to work in only some cases, and before you ask, YES, ground is connected from the Arduino Mega 2560 to the DFPlayer Mini. It has a compact form factor of 38 x 54mm and is an excellent solution for developing projects based on ATmega2560. Arduino mega has 4 Serial channels, I am using Serial Channel-1 for my application. The "Arduino Mega 2560 Pro Mini" board is compatible with the Arduino Mega 2560. But the size, pinout, circuit and functionality will be identical. The boards might look slightly different than in the pictures(like text on board). in gnd out en bp 1 2 3 4 5 6 7 8 9 10 11 1 12 2 3 4 5 6 7 8 9 10 11 12 1 2 pb5(sck) 17 pb7(xtal2/tosc2) 8 pb6(xtal1/tosc1) 7 gnd 3 gnd 21 vcc 4 vcc 6 agnd 5 aref 20. Please Note: This is a generic board, and can be manufactured by a variety of different manufacturers. It is assembled with a genuine Atmel ATmega2560 microcontroller and the low cost CH340G USB-UART interface. This is a low cost and miniature version of the popular Arduino Mega 2560. Input Voltage: 5V via Micro-USB connector, or 6V to 9V DC (recommended) via Vin & GND pins.
