It contains everything needed to support the microcontroller simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.

ARDUINO MEGA 2560 R3 SOFTWARE
Arduino can be used to develop stand-alone interactive objects or can be connected to software on your computer (e.g.
Thus, I am looking for a list of parts that someone has used to order an Arduino Mega 2560/Clone that is known to be compatible with JLCPCB's SMT assembly requirements (other than parts such as the usb connector, crystal oscillator, power jack, etc.).Arduino is an open-source physical computing platform based on a simple i/o board and a development environment that implements the Processing/Wiring language.
As I've ruled out every other possibility, the cause must be the hardware. I receive an 'avrdude: stk500v2_ReceiveMessage(): timeout'. The error occurs when trying to upload a sketch. I am able to flash both chips with a USBasp programmer via the ICSP pins at each respective chip and have the board recognized as an Arduino Mega 2560 in the Arduino IDE by both my Mac and my PC. I understand how serial communication is conducted between the ATmega 16U2 and the ATmega 2560 chips. There are parts that are not recognized by JLCPCB's import tool, JLCPCB does not carry the part needed, or the limit of extended parts is exceeded when trying to order an SMT assembly (which I need). I know that the BOM is included with the Eagle files - the issue is that you cannot copy and paste that BOM into JLCPCB (at least not in a clean way that I'm aware of).
I used the official Arduino Mega 2560 R3 eagle files to create the board.
In case you are facing problem while sending data through TX RX of the Arduino from an external Device which has for example a USB port, then a USB to Serial converter is needed in this case, the Arduino Mega has a ATmega16U2 which is a 8bit AVR MCU that has a firmware uploaded to it to play the role of USB to serial converter. Talking about the communication over serial port, if you are establishing this communication from any other external MCU straight to your Arduino MCU then just connect the TX of your Arduino to RX of the external MCU and RX of your Arduino to the TX of the external MCU and it should necessarily have both GND of both parts connected together (common ground) then make sure that you are having the same baud rate of the serial ports set in both MCUs (like 9600 bps). First of all, please change the post topic to "general discussion" in order to get more interaction with your post since this is not 100% JLCPCB related post.Ībout your request, you better search for the Arduino mega schematic instead of searching of the needed parts because you will have the BOM from the appropriate schematic, please check this public project that it shows what are the components that the mega has been built around : ()
