Polish Pi

[ZOUjiarui]

I locked up the Google docs link and so far no one has sent a message to get my Google docs. This ancient and cheap pi is really a good learning machine.

I copied the drawings of 6103 from the PCB layout I found through Alibaba's Xianyu software, and I damaged their commercial interests.

The same avt5196, the Indonesians modified it better, I saw two models.
One adds ground balance.
The other one not only has ground balance, but also has the function of discharging iron, and it also has the sound of treasure hunting.

I forgot. I don't know if it's useful, but the only useful information is this picture.

This circuit is the simplest and most powerful, and it is the commercial pi in China.

do you have the pcb layout file?

[ZOUjiarui]

I didn't. I had a little PCB that was added to the original polones. There were a lot of videos, and they deleted it.

Hi Zoujiarui,

can you upload a circuit diagram for the PCB you posted in post #259 as well?

thanks.

thanks.

I don't have the circuit diagram of this PCB, this diagram is the only information.

This is the circuit diagram. You need to add a capacitor of 10uf .pin 1-8 lm386.

because the Polish PI changes its oxylator or pulse rate over time, having to keep adjusting it all the time. It could be the quality of the parts or some assembly error
