Long tracks can pickup noise a lot easier. Make sure your analog and digital grounds are connected only at one point. They might lead to EMI problems. I have made a PCB with Fritzing and I would really appreciate it if you could help me with a “sanity check” of my design and pt3214 selection. I have no prior PCB designing experience and my electronics knowledge is basic. I built PCB using application circuit from datasheet.
I’m experiencing some strange drawing bugs in Fritzing, some of them can be seen in the schematic file and on the IC labeling.
Audio does’nt go throu PT As in the pictures pt22314 have attached, all capacitors should be close to the pins of IC.
I hope the choices I have made does not degrade the audio ;t2314 noticeably and is still “safe” enough. PT audio processor PCB. Since this is a simple design, the board you have designed should work, but I would like to point out things that would save you from having troubles in more complicated designs.
PT audio processor PCB
Does someone have some example of sketch? I finalized the updates and tried to implement as many of the suggestions as possible without total rerouting. Also, make sure that all your digital and analog signal grounds have different paths until they meet the IC.
Write some sketch with some instructions and send to Arduino volume,channel, etc. You definitely don’t want that.

Vias must be apart from component pads. The schematic is not my proudest moment I focused my attention on the PCB Otherwise you will have a digital noise in your analog circuitry, it can even cause parasitic oscillations. Some additional guidelines for a good PCB design: I’m currently implementing several of the changes you propose and will post updated files later.
Also it acts as additional power supply when short pulses of current are needed for the IC. This capacitor is needed to filter out the noise coming from and going back to power supply rail. Thanks for the great feedback VaidasZ!
For every power input pin of the IC especially digital IC’s you must place a p2314 capacitor a capacitor from Vcc,Vdd, Luckily these are only minor problems. Hi, please can you put your code here. Also it will affect the impedance of transmission lines. This is mainly to be able to create an even more compact module but it means that I have left out the input surge protection resistors in the PT example.
Otherwise when soldering in the oven, the solder will be sucked by via. I have also included a few photos of commercial implementations of the PT for reference: I bought a pair of 3w 4ohm USB speakers that I intend to gut and use.
There must be at least some solder mask between them. From GitHub download library PT Please let us know your experiences with these ICs.
Try to keep track widths and corners consistent – this makes the board look better; Avoid 90 degrees corners on the PCB tracks.
Thank you, Best regards.

Keep signal tracks as short as possible. I have opted for resistors and ceramic capacitors and a couple of ceramic capacitors. I put PT on it with others elements. PT datasheet MS datasheet A couple of screen captures from the datasheet: I bought a Pt chip, I have build the board but I can’t write the sketch. This might lead to arcing in high voltage circuits, increase EMI radiation in high pt234 and power circuits.
Some homemade uses of the PT For this reason I would suggest placing components in different way.

Most of the audio paths are short, exept for the two audio channels that needs to cross the IC due to the IC’s pinout.
Please share PT example arduino code. From electrical point of view: This might lead to noisy analog signal and even parasitic oscillations.
