What is the best PCB?

[zebedeu]

Hi, my name is Caio
I am Brazilian and I was searching for a long time how to build a module.
I found the MegaDrum the best! But I am still with some doubts:

1 -) What is the difference between the versions of the layout Synthex? I have found only the PCB v2.5
2 -) What is the difference between the project and Synthex version of Dmitri?
3 -) Is there any version of Dmitri in which the two plates are in a single PCB?

sorry for my bad english

Regards,

Caio

It is right on the first page of this subforum: MegaDrum 56 inputs latest schematic and PCB

Thank you Dmitri,

I am in doubt which of the two schemes I ride the 2.5v or the one you sent me.
which do you recommend?
CI which should I buy from you?
you have to send me all the ICs of the project?

[dmitri]

I don't sell PCB's, individual ICs or any other parts.

I do not understand ... I do not have to buy the Atmega with you?
or I can buy here and I even make programming?

[dmitri]

If you are soldering and building MegaDrum yourself I can send you only Atmega644 with the protected bootloader. I don't send any other ICs, PCBs, , resistors, capacitors, wires or any other parts.

I understand!
what procedure to acquire the Atmega644?
is there any way to test the project, while the IC is not enough?

Either start a new Atmega bulk order or PM me.

is there any way to test the project, while the IC is not enough?

I didn't understand the question.

It is possible to test the MegaDrum before receiving the CI that I will buy with you?
while the Atmega644 with the protected bootloader comes to Brazil??

If you're not sure about your PCB making and soldering skills you can, and probably should, test it with a multimeter for shorts, breaks, bad soldering end etc.
