Arduino Mega2560 R3 pinouts photo

I have the (reference to company selling counterfeit product removed by moderator) board too I found it's best to print the schematic to see which pins and ports that where extened to the stackable connector. Im using 6 external interrrupts on mine

Do i see it right, that there are 15 PWM outputs (2-13 + 44 45 46)? several sites of the shop do say, that there are just 14. The 15 would be important for my project.

Nantonos, Nice Work on this!

May I use this on the http://ArduinoInfo.Info WIKI? I'd link back to your original as well.

Thanks!

A table of pins 1-100 on the Atmega2560 with the corresponding Arduino Mega pin number mappings would be ideal.

Hi there,

I noticed that the pdf drawing on the Arduino Product web page shows 2 crystals 16Mcs, however there's only one on the board??
Furthermore, the downloadable eagle files do not open in my Eagle: Invalid data error

I am experiencing communication probs, possibly coming from one clock source for the 2560 & 16U2, derived from 1 crystal, only.

Could you please clarify?

Thank's

Hi there,

Just out of curiosity does an Ethernet shield connect the same way and is just as efficient on the mega? Or must I get a new style of shield. One other question would be does the mega have a sufficient amount of memory more than the Uno for SRAM that it would make a difference for a solid grouping of text for multiple strings in a program?

Thanks for posting this. That is a great reference to keep on hand.

This is a site which gives you pin-out of the various Arduino boards.

The "tripple x" in the site address does not mean it is a porn site except to show you the nakedness of the pins.
Hope it was of help.

thank you

Hi,

I am wondering which pin is for DAC.

Thanks

I2C DAC? SPI DAC? Parallel interface DAC?
Atmega2560 itself does not have a DAC.

Hi,

Could you tell me how to convert PWM to Analog if it is possible?

Thanks

Run it thru an RC lowpass filter.
Here's PWM, from 0-25-50-75-100-125-150-175-200-225-250 with 10K resistor and 4.7uF cap.
Or may 4.7K resistor and 10uF cap, I forget which.

You may want different values depending on what frequency response you want to achieve.

Thanks a lot.

Nantonos: just add table with your image :wink:

An other table :

Please find the attached file for the schematic of ArduinoMEGA which shows some mismatch with the pictorial digarm of ArduinoMEGA of #1.
