Hi Sir,
I am Planning to design the Arduino Mega + Arduino Ethernet Shield 2 board circuit with the Single board for my customized application. For this what are all the cares to be taken in the Circuit while designing in the Single board. Kindly let us know. I had seen the Concept of Ethernet Data transfer from Development Kit to PC and Vice versa. Kindly help on this.
And also kindly share the latest circuitry of arduinomega 2560 and Arduino Ethernet Shield 2 board (With Wiznet Controller W5500). It will be useful to me for designing the circuit.
I have attached the Circuit available in the Document. kindly let us know this is the Final Circuit to interface Arduino Mega with Arduino Ethernet shield 2 board.?
unless you are planning to make tens to hundreds of the boards it is probably simpler and cheaper to purchase industral quality Mega and ethernet boards, e.g. a wed search for arduino mega industralised will give you plenty of links
have you implemented a prototype system to test that the combination of Mega+ethernet board meets the requirements specification?
I had tested the Arduino Mega Development + Arduino Ethernet shield 2 Development Board Interface. Full Software code is not yet done. Parallely i have to work for My own hardware in Single PCB.
make sure you fully test the prototype in the application environment - even then it will probably take two or three itterations to get a fully working PCB
are there other components required? e.g. relays, sensors, WiFi, Bluetooth, ?
EDIT: also if you are implementing this for an end-user expect them to change the specification on you
1.Planning to connect 8 Nos of Separate Unit ATmega328 Controller to the Mega 2560 seperate unit through Serial Port(RS-485 Driver). The Same Mega will be interfaced to the Ethernet Port to connect to PC to read the data from the Mega. Whenever the Atmega328 Controller will send the Data to the Mega 2560 through Serial Port and Mega will send the Data to the PC. This have to be done with Every 1 sec interval Continuously.
2. External Interrupt (2 Nos) to be used in Both ATmega328 and Mega 2560
3. 1 12C port in the Atmega328 should interface with two Digital potentiometer(i2C) and two DAC(12C)
4. Two ADC port to be used in the ATMega328 controller.
5. 8 Nos ATmeg328 (Seperate unit)--> Serial Port ---> Mega 2560 --> Ethernet Port ---> PC
This have to be done for my application.
6. Data have to be continuously(Every 1 sec interval) read from PC to ATmega328 Via Mega 2560.
7. Data have to be written from PC to ATmega328 via Mega 2560.
These are my Main requirements for my application. Is it can be achieved using this Design. Will there be anything to be tested? Kindly let us know.
Need Help
I'v all documentation to build Arduino Ethernet Shield 2, but there are some components designator issues :
For designator R22 and R23, the value mentioned is 10k, while the description mentioned is 100R 0805, what is correct value of R22 and R23?
For designator C17, C37, C38, C44 (22Uf 25V capacitor with package SMC_B), what is exact part number
For the four connectors with the bit numbers JANALOG, JLOW, POWER, and JHIGH, the BOM shows that they are installed in a press-fit manner. Can the holes be enlarged to 1.0mm and replaced with ordinary soldered connectors?
I checked with Zoom Lens, The two resistor which you have marked is showing as 68x. i think it is 68k. What is the Value which is showing in your board?
yes, the schematic says 10K, but Bill of Material that I generate from Eagle mention different value. 10 K and 100R 0805 footprint. otherwise your board shows 68X. which value should I follow?
I am also in the Process of designing the customized PCB with this arduino Ethernet shield 2 board Circuit. Expert team in the Forum have to be answer for this.
