hello guys, and I finally 'got the kit to build, but' I have not found any pattern inside. you have some scheme recently so I can check?

To your scheme

Hi Aleks85, could you please share the SprintLayout PCB in .lay format?

[Aleks85]

No problem

Thank you very much Aleks85

Thank you so much, Aleks85, for sharing with us all!
Have you built the IDX Pro using this PCB?
If so, what details should I keep in mind to successfully build it?

[Aleks85]

Yes, I built a Whites on this board. I used an AD548 input op amp, which is the best alternative to the LF441, and I used an LF444 instead of the LF347 – everything worked perfectly. It's hard to find high-quality ICs in my region, which is very important. It's also important to set the exact frequency – 6.59 kHz and 4.6 kHz. This metal detector is single-tone, so it's a good idea to use a VDI adapter on the PIC microcontroller, but the device works perfectly without it too. The main thing is to use high-quality electronic components, and everything will work perfectly.

Thank you so much Aleks85 for the details!
