'KROT2-XM' (mole), new project Xmega32

[smity]

Hello. PCB did "TCВ" Forum "radio band." If there is interest, I can ask him (and post here) PCB format PCAD 6.

[WM6]

Why PCAD6 now, smity?

I just downloaded and istalled SprintLayout6 to manage this KROT2 PCB only ..

Isn't PCB you posted in post #19 in LAY format?

[Geo]

For me it's OK the Lay format.

I have some low noise op.amp (AD797,AD844, NE5534, LF357) and i want to replace the MPC601 with one of them. Can anyone tell me if the ics that i own may work here with so low voltage??

[smity]

Need amplifier Rail-to-Rail and low-voltage power supply. Your not fit. Look МСP601, MСP633, AD8091 ...

Thanks, if so then i"ll use MCP601 as the author writes....

In SMD version of PCB it is possible to use LMH6642 too.

But in DIP?????

[Geo]

And the pcb for DIP version....

[WM6]

Very nice work Geo, even with fine lines.

[Geo]

Thanks WM6.
At afternoon i made another one as spare .
But i can't see C23, C24 and zener D4 on both pcbs smd and dip version. Why????
Maybe smity knows....

Regards

C23, C24, are placed near sources of energy consumption, ... A Zener diode is a "foolproof" ... You do not have to put ....

I will write at once, so you do not have a question. Transmitting coil is connected to pin 8 and the ground. Cable to use separate screens! This is very important!

Hi smity, I do not understand this.
Where cable screen neeed to be connected? At which point in schematic?

[smity]

Screens TX and RX in the cable are separate. Connect the screen to the printed circuit board in the receiver.
